//! # Camera Calibration and 3D Reconstruction
//!
//! The functions in this section use a so-called pinhole camera model. The view of a scene
//! is obtained by projecting a scene's 3D point  into the image plane using a perspective
//! transformation which forms the corresponding pixel . Both  and  are
//! represented in homogeneous coordinates, i.e. as 3D and 2D homogeneous vector respectively. You will
//! find a brief introduction to projective geometry, homogeneous vectors and homogeneous
//! transformations at the end of this section's introduction. For more succinct notation, we often drop
//! the 'homogeneous' and say vector instead of homogeneous vector.
//!
//! The distortion-free projective transformation given by a pinhole camera model is shown below.
//!
//! 
//!
//! where  is a 3D point expressed with respect to the world coordinate system,
//!  is a 2D pixel in the image plane,  is the camera intrinsic matrix,
//!  and  are the rotation and translation that describe the change of coordinates from
//! world to camera coordinate systems (or camera frame) and  is the projective transformation's
//! arbitrary scaling and not part of the camera model.
//!
//! The camera intrinsic matrix  (notation used as in [Zhang2000](https://docs.opencv.org/4.10.0/d0/de3/citelist.html#CITEREF_Zhang2000) and also generally notated
//! as ) projects 3D points given in the camera coordinate system to 2D pixel coordinates, i.e.
//!
//! 
//!
//! The camera intrinsic matrix  is composed of the focal lengths  and , which are
//! expressed in pixel units, and the principal point , that is usually close to the
//! image center:
//!
//! 
//!
//! and thus
//!
//! 
//!
//! The matrix of intrinsic parameters does not depend on the scene viewed. So, once estimated, it can
//! be re-used as long as the focal length is fixed (in case of a zoom lens). Thus, if an image from the
//! camera is scaled by a factor, all of these parameters need to be scaled (multiplied/divided,
//! respectively) by the same factor.
//!
//! The joint rotation-translation matrix  is the matrix product of a projective
//! transformation and a homogeneous transformation. The 3-by-4 projective transformation maps 3D points
//! represented in camera coordinates to 2D points in the image plane and represented in normalized
//! camera coordinates  and :
//!
//! 
//!
//! The homogeneous transformation is encoded by the extrinsic parameters  and  and
//! represents the change of basis from world coordinate system  to the camera coordinate sytem
//! . Thus, given the representation of the point  in world coordinates, , we
//! obtain 's representation in the camera coordinate system, , by
//!
//! 
//!
//! This homogeneous transformation is composed out of , a 3-by-3 rotation matrix, and , a
//! 3-by-1 translation vector:
//!
//! 
//!
//! and therefore
//!
//! 
//!
//! Combining the projective transformation and the homogeneous transformation, we obtain the projective
//! transformation that maps 3D points in world coordinates into 2D points in the image plane and in
//! normalized camera coordinates:
//!
//! 
//!
//! with  and . Putting the equations for instrincs and extrinsics together, we can write out
//!  as
//!
//! 
//!
//! If , the transformation above is equivalent to the following,
//!
//! 
//!
//! with
//!
//! 
//!
//! The following figure illustrates the pinhole camera model.
//!
//! 
//!
//! Real lenses usually have some distortion, mostly radial distortion, and slight tangential distortion.
//! So, the above model is extended as:
//!
//! 
//!
//! where
//!
//! 
//!
//! with
//!
//! 
//!
//! and
//!
//! 
//!
//! if .
//!
//! The distortion parameters are the radial coefficients , , , , , and 
//! , and  are the tangential distortion coefficients, and , , , and ,
//! are the thin prism distortion coefficients. Higher-order coefficients are not considered in OpenCV.
//!
//! The next figures show two common types of radial distortion: barrel distortion
//! ( monotonically decreasing)
//! and pincushion distortion ( monotonically increasing).
//! Radial distortion is always monotonic for real lenses,
//! and if the estimator produces a non-monotonic result,
//! this should be considered a calibration failure.
//! More generally, radial distortion must be monotonic and the distortion function must be bijective.
//! A failed estimation result may look deceptively good near the image center
//! but will work poorly in e.g. AR/SFM applications.
//! The optimization method used in OpenCV camera calibration does not include these constraints as
//! the framework does not support the required integer programming and polynomial inequalities.
//! See [issue #15992](https://github.com/opencv/opencv/issues/15992) for additional information.
//!
//! 
//! 
//!
//! In some cases, the image sensor may be tilted in order to focus an oblique plane in front of the
//! camera (Scheimpflug principle). This can be useful for particle image velocimetry (PIV) or
//! triangulation with a laser fan. The tilt causes a perspective distortion of  and
//! . This distortion can be modeled in the following way, see e.g. [Louhichi07](https://docs.opencv.org/4.10.0/d0/de3/citelist.html#CITEREF_Louhichi07).
//!
//! 
//!
//! where
//!
//! 
//!
//! and the matrix  is defined by two rotations with angular parameter
//!  and , respectively,
//!
//! 
//!
//! In the functions below the coefficients are passed or returned as
//!
//! 
//!
//! vector. That is, if the vector contains four elements, it means that  . The distortion
//! coefficients do not depend on the scene viewed. Thus, they also belong to the intrinsic camera
//! parameters. And they remain the same regardless of the captured image resolution. If, for example, a
//! camera has been calibrated on images of 320 x 240 resolution, absolutely the same distortion
//! coefficients can be used for 640 x 480 images from the same camera while , ,
//! , and  need to be scaled appropriately.
//!
//! The functions below use the above model to do the following:
//!
//! * Project 3D points to the image plane given intrinsic and extrinsic parameters.
//! * Compute extrinsic parameters given intrinsic parameters, a few 3D points, and their
//! projections.
//! * Estimate intrinsic and extrinsic camera parameters from several views of a known calibration
//! pattern (every view is described by several 3D-2D point correspondences).
//! * Estimate the relative position and orientation of the stereo camera "heads" and compute the
//! *rectification* transformation that makes the camera optical axes parallel.
//!
//! Homogeneous Coordinates
//! Homogeneous Coordinates are a system of coordinates that are used in projective geometry. Their use
//! allows to represent points at infinity by finite coordinates and simplifies formulas when compared
//! to the cartesian counterparts, e.g. they have the advantage that affine transformations can be
//! expressed as linear homogeneous transformation.
//!
//! One obtains the homogeneous vector  by appending a 1 along an n-dimensional cartesian
//! vector  e.g. for a 3D cartesian vector the mapping  is:
//!
//! 
//!
//! For the inverse mapping , one divides all elements of the homogeneous vector
//! by its last element, e.g. for a 3D homogeneous vector one gets its 2D cartesian counterpart by:
//!
//! 
//!
//! if .
//!
//! Due to this mapping, all multiples , for , of a homogeneous point represent
//! the same point . An intuitive understanding of this property is that under a projective
//! transformation, all multiples of  are mapped to the same point. This is the physical
//! observation one does for pinhole cameras, as all points along a ray through the camera's pinhole are
//! projected to the same image point, e.g. all points along the red ray in the image of the pinhole
//! camera model above would be mapped to the same image coordinate. This property is also the source
//! for the scale ambiguity s in the equation of the pinhole camera model.
//!
//! As mentioned, by using homogeneous coordinates we can express any change of basis parameterized by
//!  and  as a linear transformation, e.g. for the change of basis from coordinate system
//! 0 to coordinate system 1 becomes:
//!
//! 
//!
//!
//! Note:
//! * Many functions in this module take a camera intrinsic matrix as an input parameter. Although all
//! functions assume the same structure of this parameter, they may name it differently. The
//! parameter's description, however, will be clear in that a camera intrinsic matrix with the structure
//! shown above is required.

/// camera parameters. Both the object-releasing method and standard method are supported by this
/// function. Use the parameter **iFixedPoint** for method selection. In the internal implementation,
/// [calibrate_camera] is a wrapper for this function.
///
/// ## Parameters
/// * objectPoints: Vector of vectors of calibration pattern points in the calibration pattern
/// coordinate space. See [calibrate_camera] for details. If the method of releasing object to be used,
/// the identical calibration board must be used in each view and it must be fully visible, and all
/// objectPoints[i] must be the same and all points should be roughly close to a plane. **The calibration
/// target has to be rigid, or at least static if the camera (rather than the calibration target) is
/// shifted for grabbing images.**
/// * imagePoints: Vector of vectors of the projections of calibration pattern points. See
/// [calibrate_camera] for details.
/// * imageSize: Size of the image used only to initialize the intrinsic camera matrix.
/// * iFixedPoint: The index of the 3D object point in objectPoints[0] to be fixed. It also acts as
/// a switch for calibration method selection. If object-releasing method to be used, pass in the
/// parameter in the range of [1, objectPoints[0].size()-2], otherwise a value out of this range will
/// make standard calibration method selected. Usually the top-right corner point of the calibration
/// board grid is recommended to be fixed when object-releasing method being utilized. According to
/// \cite strobl2011iccv, two other points are also fixed. In this implementation, objectPoints[0].front
/// and objectPoints[0].back.z are used. With object-releasing method, accurate rvecs, tvecs and
/// newObjPoints are only possible if coordinates of these three fixed points are accurate enough.
/// * cameraMatrix: Output 3x3 floating-point camera matrix. See [calibrate_camera] for details.
/// * distCoeffs: Output vector of distortion coefficients. See [calibrate_camera] for details.
/// * rvecs: Output vector of rotation vectors estimated for each pattern view. See [calibrate_camera]
/// for details.
/// * tvecs: Output vector of translation vectors estimated for each pattern view.
/// * newObjPoints: The updated output vector of calibration pattern points. The coordinates might
/// be scaled based on three fixed points. The returned coordinates are accurate only if the above
/// mentioned three fixed points are accurate. If not needed, noArray() can be passed in. This parameter
/// is ignored with standard calibration method.
/// * stdDeviationsIntrinsics: Output vector of standard deviations estimated for intrinsic parameters.
/// See [calibrate_camera] for details.
/// * stdDeviationsExtrinsics: Output vector of standard deviations estimated for extrinsic parameters.
/// See [calibrate_camera] for details.
/// * stdDeviationsObjPoints: Output vector of standard deviations estimated for refined coordinates
/// of calibration pattern points. It has the same size and order as objectPoints[0] vector. This
/// parameter is ignored with standard calibration method.
/// * perViewErrors: Output vector of the RMS re-projection error estimated for each pattern view.
/// * flags: Different flags that may be zero or a combination of some predefined values. See
/// [calibrate_camera] for details. If the method of releasing object is used, the calibration time may
/// be much longer. CALIB_USE_QR or CALIB_USE_LU could be used for faster calibration with potentially
/// less precise and less stable in some rare cases.
/// * criteria: Termination criteria for the iterative optimization algorithm.
///
/// ## Returns
/// the overall RMS re-projection error.
///
/// The function estimates the intrinsic camera parameters and extrinsic parameters for each of the
/// views.

/// Finds the camera intrinsic and extrinsic parameters from several views of a calibration

///
/// ## Parameters
/// * objectPoints: In the new interface it is a vector of vectors of calibration pattern points in
/// the calibration pattern coordinate space (e.g. std::vector>). The outer
/// vector contains as many elements as the number of pattern views. If the same calibration pattern
/// is shown in each view and it is fully visible, all the vectors will be the same. Although, it is
/// possible to use partially occluded patterns or even different patterns in different views. Then,
/// the vectors will be different. Although the points are 3D, they all lie in the calibration pattern's
/// XY coordinate plane (thus 0 in the Z-coordinate), if the used calibration pattern is a planar rig.
/// In the old interface all the vectors of object points from different views are concatenated
/// together.
/// * imagePoints: In the new interface it is a vector of vectors of the projections of calibration
/// pattern points (e.g. std::vector>). imagePoints.size() and
/// objectPoints.size(), and imagePoints[i].size() and objectPoints[i].size() for each i, must be equal,
/// respectively. In the old interface all the vectors of object points from different views are
/// concatenated together.
/// * imageSize: Size of the image used only to initialize the camera intrinsic matrix.
/// * cameraMatrix: Input/output 3x3 floating-point camera intrinsic matrix
///  . If [CALIB_USE_INTRINSIC_GUESS]
/// and/or [CALIB_FIX_ASPECT_RATIO], [CALIB_FIX_PRINCIPAL_POINT] or [CALIB_FIX_FOCAL_LENGTH]
/// are specified, some or all of fx, fy, cx, cy must be initialized before calling the function.
/// * distCoeffs: Input/output vector of distortion coefficients
/// .
/// * rvecs: Output vector of rotation vectors ([Rodrigues] ) estimated for each pattern view
/// (e.g. std::vector>). That is, each i-th rotation vector together with the corresponding
/// i-th translation vector (see the next output parameter description) brings the calibration pattern
/// from the object coordinate space (in which object points are specified) to the camera coordinate
/// space. In more technical terms, the tuple of the i-th rotation and translation vector performs
/// a change of basis from object coordinate space to camera coordinate space. Due to its duality, this
/// tuple is equivalent to the position of the calibration pattern with respect to the camera coordinate
/// space.
/// * tvecs: Output vector of translation vectors estimated for each pattern view, see parameter
/// describtion above.
/// * stdDeviationsIntrinsics: Output vector of standard deviations estimated for intrinsic
/// parameters. Order of deviations values:
///  If one of parameters is not estimated, it's deviation is equals to zero.
/// * stdDeviationsExtrinsics: Output vector of standard deviations estimated for extrinsic
/// parameters. Order of deviations values:  where M is
/// the number of pattern views.  are concatenated 1x3 vectors.
/// * perViewErrors: Output vector of the RMS re-projection error estimated for each pattern view.
/// * flags: Different flags that may be zero or a combination of the following values:
/// * [CALIB_USE_INTRINSIC_GUESS] cameraMatrix contains valid initial values of
/// fx, fy, cx, cy that are optimized further. Otherwise, (cx, cy) is initially set to the image
/// center ( imageSize is used), and focal distances are computed in a least-squares fashion.
/// Note, that if intrinsic parameters are known, there is no need to use this function just to
/// estimate extrinsic parameters. Use [solvePnP] instead.
/// * [CALIB_FIX_PRINCIPAL_POINT] The principal point is not changed during the global
/// optimization. It stays at the center or at a different location specified when
/// [CALIB_USE_INTRINSIC_GUESS] is set too.
/// * [CALIB_FIX_ASPECT_RATIO] The functions consider only fy as a free parameter. The
/// ratio fx/fy stays the same as in the input cameraMatrix . When
/// [CALIB_USE_INTRINSIC_GUESS] is not set, the actual input values of fx and fy are
/// ignored, only their ratio is computed and used further.
/// * [CALIB_ZERO_TANGENT_DIST] Tangential distortion coefficients  are set
/// to zeros and stay zero.
/// * [CALIB_FIX_FOCAL_LENGTH] The focal length is not changed during the global optimization if
/// [CALIB_USE_INTRINSIC_GUESS] is set.
/// * [CALIB_FIX_K1],..., [CALIB_FIX_K6] The corresponding radial distortion
/// coefficient is not changed during the optimization. If [CALIB_USE_INTRINSIC_GUESS] is
/// set, the coefficient from the supplied distCoeffs matrix is used. Otherwise, it is set to 0.
/// * [CALIB_RATIONAL_MODEL] Coefficients k4, k5, and k6 are enabled. To provide the
/// backward compatibility, this extra flag should be explicitly specified to make the
/// calibration function use the rational model and return 8 coefficients or more.
/// * [CALIB_THIN_PRISM_MODEL] Coefficients s1, s2, s3 and s4 are enabled. To provide the
/// backward compatibility, this extra flag should be explicitly specified to make the
/// calibration function use the thin prism model and return 12 coefficients or more.
/// * [CALIB_FIX_S1_S2_S3_S4] The thin prism distortion coefficients are not changed during
/// the optimization. If [CALIB_USE_INTRINSIC_GUESS] is set, the coefficient from the
/// supplied distCoeffs matrix is used. Otherwise, it is set to 0.
/// * [CALIB_TILTED_MODEL] Coefficients tauX and tauY are enabled. To provide the
/// backward compatibility, this extra flag should be explicitly specified to make the
/// calibration function use the tilted sensor model and return 14 coefficients.
/// * [CALIB_FIX_TAUX_TAUY] The coefficients of the tilted sensor model are not changed during
/// the optimization. If [CALIB_USE_INTRINSIC_GUESS] is set, the coefficient from the
/// supplied distCoeffs matrix is used. Otherwise, it is set to 0.
/// * criteria: Termination criteria for the iterative optimization algorithm.
///
/// ## Returns
/// the overall RMS re-projection error.
///
/// The function estimates the intrinsic camera parameters and extrinsic parameters for each of the
/// views. The algorithm is based on [Zhang2000](https://docs.opencv.org/4.10.0/d0/de3/citelist.html#CITEREF_Zhang2000) and [BouguetMCT](https://docs.opencv.org/4.10.0/d0/de3/citelist.html#CITEREF_BouguetMCT) . The coordinates of 3D object
/// points and their corresponding 2D projections in each view must be specified. That may be achieved
/// by using an object with known geometry and easily detectable feature points. Such an object is
/// called a calibration rig or calibration pattern, and OpenCV has built-in support for a chessboard as
/// a calibration rig (see [findChessboardCorners]). Currently, initialization of intrinsic
/// parameters (when [CALIB_USE_INTRINSIC_GUESS] is not set) is only implemented for planar calibration
/// patterns (where Z-coordinates of the object points must be all zeros). 3D calibration rigs can also
/// be used as long as initial cameraMatrix is provided.
///
/// The algorithm performs the following steps:
///
/// * Compute the initial intrinsic parameters (the option only available for planar calibration
/// patterns) or read them from the input parameters. The distortion coefficients are all set to
/// zeros initially unless some of CALIB_FIX_K? are specified.
///
/// * Estimate the initial camera pose as if the intrinsic parameters have been already known. This is
/// done using [solvePnP] .
///
/// * Run the global Levenberg-Marquardt optimization algorithm to minimize the reprojection error,
/// that is, the total sum of squared distances between the observed feature points imagePoints and
/// the projected (using the current estimates for camera parameters and the poses) object points
/// objectPoints. See [projectPoints] for details.
///
///
/// Note:
/// If you use a non-square (i.e. non-N-by-N) grid and [findChessboardCorners] for calibration,
/// and [calibrateCamera] returns bad values (zero distortion coefficients,  and
///  very far from the image center, and/or large differences between  and
///  (ratios of 10:1 or more)), then you are probably using patternSize=cvSize(rows,cols)
/// instead of using patternSize=cvSize(cols,rows) in [findChessboardCorners].
///

/// The function may throw exceptions, if unsupported combination of parameters is provided or
/// the system is underconstrained.

/// Finds the camera intrinsic and extrinsic parameters from several views of a calibration
/// pattern.
///
/// ## Parameters
/// * objectPoints: In the new interface it is a vector of vectors of calibration pattern points in
/// the calibration pattern coordinate space (e.g. std::vector>). The outer
/// vector contains as many elements as the number of pattern views. If the same calibration pattern
/// is shown in each view and it is fully visible, all the vectors will be the same. Although, it is
/// possible to use partially occluded patterns or even different patterns in different views. Then,
/// the vectors will be different. Although the points are 3D, they all lie in the calibration pattern's
/// XY coordinate plane (thus 0 in the Z-coordinate), if the used calibration pattern is a planar rig.
/// In the old interface all the vectors of object points from different views are concatenated
/// together.
/// * imagePoints: In the new interface it is a vector of vectors of the projections of calibration
/// pattern points (e.g. std::vector>). imagePoints.size() and
/// objectPoints.size(), and imagePoints[i].size() and objectPoints[i].size() for each i, must be equal,
/// respectively. In the old interface all the vectors of object points from different views are
/// concatenated together.
/// * imageSize: Size of the image used only to initialize the camera intrinsic matrix.
/// * cameraMatrix: Input/output 3x3 floating-point camera intrinsic matrix
///  . If [CALIB_USE_INTRINSIC_GUESS]
/// and/or [CALIB_FIX_ASPECT_RATIO], [CALIB_FIX_PRINCIPAL_POINT] or [CALIB_FIX_FOCAL_LENGTH]
/// are specified, some or all of fx, fy, cx, cy must be initialized before calling the function.
/// * distCoeffs: Input/output vector of distortion coefficients
/// .
/// * rvecs: Output vector of rotation vectors ([Rodrigues] ) estimated for each pattern view
/// (e.g. std::vector>). That is, each i-th rotation vector together with the corresponding
/// i-th translation vector (see the next output parameter description) brings the calibration pattern
/// from the object coordinate space (in which object points are specified) to the camera coordinate
/// space. In more technical terms, the tuple of the i-th rotation and translation vector performs
/// a change of basis from object coordinate space to camera coordinate space. Due to its duality, this
/// tuple is equivalent to the position of the calibration pattern with respect to the camera coordinate
/// space.
/// * tvecs: Output vector of translation vectors estimated for each pattern view, see parameter
/// describtion above.
/// * stdDeviationsIntrinsics: Output vector of standard deviations estimated for intrinsic
/// parameters. Order of deviations values:
///  If one of parameters is not estimated, it's deviation is equals to zero.
/// * stdDeviationsExtrinsics: Output vector of standard deviations estimated for extrinsic
/// parameters. Order of deviations values:  where M is
/// the number of pattern views.  are concatenated 1x3 vectors.
/// * perViewErrors: Output vector of the RMS re-projection error estimated for each pattern view.
/// * flags: Different flags that may be zero or a combination of the following values:
/// * [CALIB_USE_INTRINSIC_GUESS] cameraMatrix contains valid initial values of
/// fx, fy, cx, cy that are optimized further. Otherwise, (cx, cy) is initially set to the image
/// center ( imageSize is used), and focal distances are computed in a least-squares fashion.
/// Note, that if intrinsic parameters are known, there is no need to use this function just to
/// estimate extrinsic parameters. Use [solvePnP] instead.
/// * [CALIB_FIX_PRINCIPAL_POINT] The principal point is not changed during the global
/// optimization. It stays at the center or at a different location specified when
/// [CALIB_USE_INTRINSIC_GUESS] is set too.
/// * [CALIB_FIX_ASPECT_RATIO] The functions consider only fy as a free parameter. The
/// ratio fx/fy stays the same as in the input cameraMatrix . When
/// [CALIB_USE_INTRINSIC_GUESS] is not set, the actual input values of fx and fy are
/// ignored, only their ratio is computed and used further.
/// * [CALIB_ZERO_TANGENT_DIST] Tangential distortion coefficients  are set
/// to zeros and stay zero.
/// * [CALIB_FIX_FOCAL_LENGTH] The focal length is not changed during the global optimization if
/// [CALIB_USE_INTRINSIC_GUESS] is set.
/// * [CALIB_FIX_K1],..., [CALIB_FIX_K6] The corresponding radial distortion
/// coefficient is not changed during the optimization. If [CALIB_USE_INTRINSIC_GUESS] is
/// set, the coefficient from the supplied distCoeffs matrix is used. Otherwise, it is set to 0.
/// * [CALIB_RATIONAL_MODEL] Coefficients k4, k5, and k6 are enabled. To provide the
/// backward compatibility, this extra flag should be explicitly specified to make the
/// calibration function use the rational model and return 8 coefficients or more.
/// * [CALIB_THIN_PRISM_MODEL] Coefficients s1, s2, s3 and s4 are enabled. To provide the
/// backward compatibility, this extra flag should be explicitly specified to make the
/// calibration function use the thin prism model and return 12 coefficients or more.
/// * [CALIB_FIX_S1_S2_S3_S4] The thin prism distortion coefficients are not changed during
/// the optimization. If [CALIB_USE_INTRINSIC_GUESS] is set, the coefficient from the
/// supplied distCoeffs matrix is used. Otherwise, it is set to 0.
/// * [CALIB_TILTED_MODEL] Coefficients tauX and tauY are enabled. To provide the
/// backward compatibility, this extra flag should be explicitly specified to make the
/// calibration function use the tilted sensor model and return 14 coefficients.
/// * [CALIB_FIX_TAUX_TAUY] The coefficients of the tilted sensor model are not changed during
/// the optimization. If [CALIB_USE_INTRINSIC_GUESS] is set, the coefficient from the
/// supplied distCoeffs matrix is used. Otherwise, it is set to 0.
/// * criteria: Termination criteria for the iterative optimization algorithm.

/// The function performs the Robot-World/Hand-Eye calibration using various methods. One approach consists in estimating the

/// - M. Shah, Solving the robot-world/hand-eye calibration problem using the kronecker product \cite Shah2013SolvingTR

/// - A. Li, L. Wang, and D. Wu, Simultaneous robot-world and hand-eye calibration using dual-quaternions and kronecker product \cite Li2010SimultaneousRA
///
/// The following picture describes the Robot-World/Hand-Eye calibration problem where the transformations between a robot and a world frame
/// and between a robot gripper ("hand") and a camera ("eye") mounted at the robot end-effector have to be estimated.
///
/// 
///
/// The calibration procedure is the following:
/// - a static calibration pattern is used to estimate the transformation between the target frame
/// and the camera frame
/// - the robot gripper is moved in order to acquire several poses
/// - for each pose, the homogeneous transformation between the gripper frame and the robot base frame is recorded using for
/// instance the robot kinematics
/// 
/// - for each pose, the homogeneous transformation between the calibration target frame (the world frame) and the camera frame is recorded using
/// for instance a pose estimation method (PnP) from 2D-3D point correspondences
/// 
///
/// The Robot-World/Hand-Eye calibration procedure returns the following homogeneous transformations

/// * [CALIB_CB_FILTER_QUADS] Use additional criteria (like contour area, perimeter,
/// square-like shape) to filter out false quads extracted at the contour retrieval stage.
/// * [CALIB_CB_FAST_CHECK] Run a fast check on the image that looks for chessboard corners,

/// degenerate condition when no chessboard is observed.
/// * [CALIB_CB_PLAIN] All other flags are ignored. The input image is taken as is.
/// No image processing is done to improve to find the checkerboard. This has the effect of speeding up the
/// execution of the function but could lead to not recognizing the checkerboard if the image
/// is not previously binarized in the appropriate manner.

/// are found and they are placed in a certain order (row by row, left to right in every row).
/// Otherwise, if the function fails to find all the corners or reorder them, it returns 0. For example,
/// a regular chessboard has 8 x 8 squares and 7 x 7 internal corners, that is, points where the black
/// squares touch each other. The detected coordinates are approximate, and to determine their positions
/// more accurately, the function calls #cornerSubPix. You also may use the function [corner_sub_pix] with
/// different parameters if returned coordinates are not accurate enough.

/// * patternSize: Number of inner corners per a chessboard row and column
/// ( patternSize = cv::Size(points_per_row,points_per_colum) = cv::Size(columns,rows) ).
/// * corners: Output array of detected corners.
/// * flags: Various operation flags that can be zero or a combination of the following values:
/// * [CALIB_CB_ADAPTIVE_THRESH] Use adaptive thresholding to convert the image to black
/// and white, rather than a fixed threshold level (computed from the average image brightness).
/// * [CALIB_CB_NORMALIZE_IMAGE] Normalize the image gamma with [equalize_hist] before
/// applying fixed or adaptive thresholding.
/// * [CALIB_CB_FILTER_QUADS] Use additional criteria (like contour area, perimeter,
/// square-like shape) to filter out false quads extracted at the contour retrieval stage.
/// * [CALIB_CB_FAST_CHECK] Run a fast check on the image that looks for chessboard corners,
/// and shortcut the call if none is found. This can drastically speed up the call in the
/// degenerate condition when no chessboard is observed.
/// * [CALIB_CB_PLAIN] All other flags are ignored. The input image is taken as is.
/// No image processing is done to improve to find the checkerboard. This has the effect of speeding up the
/// execution of the function but could lead to not recognizing the checkerboard if the image
/// is not previously binarized in the appropriate manner.
///
/// The function attempts to determine whether the input image is a view of the chessboard pattern and
/// locate the internal chessboard corners. The function returns a non-zero value if all of the corners
/// are found and they are placed in a certain order (row by row, left to right in every row).
/// Otherwise, if the function fails to find all the corners or reorder them, it returns 0. For example,
/// a regular chessboard has 8 x 8 squares and 7 x 7 internal corners, that is, points where the black
/// squares touch each other. The detected coordinates are approximate, and to determine their positions
/// more accurately, the function calls #cornerSubPix. You also may use the function [corner_sub_pix] with
/// different parameters if returned coordinates are not accurate enough.

/// inliers that pass the check.
///
/// ## Parameters
/// * points1: Array of N 2D points from the first image. The point coordinates should be
/// floating-point (single or double precision).
/// * points2: Array of the second image points of the same size and format as points1 .
/// * cameraMatrix1: Input/output camera matrix for the first camera, the same as in
/// [calibrateCamera]. Furthermore, for the stereo case, additional flags may be used, see below.
/// * distCoeffs1: Input/output vector of distortion coefficients, the same as in
/// [calibrateCamera].
/// * cameraMatrix2: Input/output camera matrix for the first camera, the same as in
/// [calibrateCamera]. Furthermore, for the stereo case, additional flags may be used, see below.
/// * distCoeffs2: Input/output vector of distortion coefficients, the same as in
/// [calibrateCamera].
/// * E: The output essential matrix.
/// * R: Output rotation matrix. Together with the translation vector, this matrix makes up a tuple
/// that performs a change of basis from the first camera's coordinate system to the second camera's
/// coordinate system. Note that, in general, t can not be used for this tuple, see the parameter
/// described below.
/// * t: Output translation vector. This vector is obtained by [decomposeEssentialMat] and
/// therefore is only known up to scale, i.e. t is the direction of the translation vector and has unit
/// length.
/// * method: Method for computing an essential matrix.
/// * [RANSAC] for the RANSAC algorithm.
/// * [LMEDS] for the LMedS algorithm.
/// * prob: Parameter used for the RANSAC or LMedS methods only. It specifies a desirable level of
/// confidence (probability) that the estimated matrix is correct.
/// * threshold: Parameter used for RANSAC. It is the maximum distance from a point to an epipolar
/// line in pixels, beyond which the point is considered an outlier and is not used for computing the
/// final fundamental matrix. It can be set to something like 1-3, depending on the accuracy of the
/// point localization, image resolution, and the image noise.
/// * mask: Input/output mask for inliers in points1 and points2. If it is not empty, then it marks
/// inliers in points1 and points2 for then given essential matrix E. Only these inliers will be used to
/// recover pose. In the output mask only inliers which pass the cheirality check.
///
/// This function decomposes an essential matrix using [decomposeEssentialMat] and then verifies
/// possible pose hypotheses by doing cheirality check. The cheirality check means that the
/// triangulated 3D points should have positive depth. Some details can be found in [Nister03](https://docs.opencv.org/4.10.0/d0/de3/citelist.html#CITEREF_Nister03).
///
/// This function can be used to process the output E and mask from [findEssentialMat]. In this

/// * E: The input essential matrix.
/// * points1: Array of N 2D points from the first image. The point coordinates should be
/// floating-point (single or double precision).
/// * points2: Array of the second image points of the same size and format as points1 .
/// * cameraMatrix: Camera intrinsic matrix  .
/// Note that this function assumes that points1 and points2 are feature points from cameras with the
/// same camera intrinsic matrix.
/// * R: Output rotation matrix. Together with the translation vector, this matrix makes up a tuple
/// that performs a change of basis from the first camera's coordinate system to the second camera's
/// coordinate system. Note that, in general, t can not be used for this tuple, see the parameter
/// described below.
/// * t: Output translation vector. This vector is obtained by [decomposeEssentialMat] and
/// therefore is only known up to scale, i.e. t is the direction of the translation vector and has unit
/// length.
/// * mask: Input/output mask for inliers in points1 and points2. If it is not empty, then it marks
/// inliers in points1 and points2 for the given essential matrix E. Only these inliers will be used to
/// recover pose. In the output mask only inliers which pass the chirality check.
///
/// This function decomposes an essential matrix using [decomposeEssentialMat] and then verifies

/// ```C++
/// // Example. Estimation of fundamental matrix using the RANSAC algorithm
/// int point_count = 100;
/// vector points1(point_count);
/// vector points2(point_count);
///
/// // initialize the points here ...

///
/// ## Overloaded parameters
///
/// * E: The input essential matrix.

/// * t: Output translation vector. This vector is obtained by [decomposeEssentialMat] and

/// length.
/// * focal: Focal length of the camera. Note that this function assumes that points1 and points2
/// are feature points from cameras with same focal length and principal point.
/// * pp: principal point of the camera.
/// * mask: Input/output mask for inliers in points1 and points2. If it is not empty, then it marks
/// inliers in points1 and points2 for the given essential matrix E. Only these inliers will be used to

///
/// Note:
/// * An example of how to use solvePnP for planar augmented reality can be found at

/// to its calling of [undistort_points] (around line 75 of modules/calib3d/src/solvepnp.cpp version 2.4.9)
/// which requires 2-channel information.
/// - Thus, given some data D = np.array(...) where D.shape = (N,M), in order to use a subset of
/// it as, e.g., imagePoints, one must effectively copy it into a new array: imagePoints =
/// np.ascontiguousarray(D[:,:2]).reshape((N,1,2))
/// * The methods [SOLVEPNP_DLS] and [SOLVEPNP_UPNP] cannot be used as the current implementations are
/// unstable and sometimes give completely wrong results. If you pass one of these two

/// * The minimum number of points is 4 in the general case. In the case of [SOLVEPNP_P3P] and [SOLVEPNP_AP3P]
/// methods, it is required to use exactly 4 points (the first 3 points are used to estimate all the solutions
/// of the P3P problem, the last one is used to retain the best solution that minimizes the reprojection error).
/// * With [SOLVEPNP_ITERATIVE] method and `useExtrinsicGuess=true`, the minimum number of points is 3 (3 points

/// More information is described in [calib3d_solvePnP]
///
///
/// Note:
/// * An example of how to use solvePnP for planar augmented reality can be found at
/// opencv_source_code/samples/python/plane_ar.py
/// * If you are using Python:
/// - Numpy array slices won't work as input because solvePnP requires contiguous
/// arrays (enforced by the assertion using cv::Mat::checkVector() around line 55 of
/// modules/calib3d/src/solvepnp.cpp version 2.4.9)
/// - The P3P algorithm requires image points to be in an array of shape (N,1,2) due
/// to its calling of [undistort_points] (around line 75 of modules/calib3d/src/solvepnp.cpp version 2.4.9)
/// which requires 2-channel information.
/// - Thus, given some data D = np.array(...) where D.shape = (N,M), in order to use a subset of
/// it as, e.g., imagePoints, one must effectively copy it into a new array: imagePoints =
/// np.ascontiguousarray(D[:,:2]).reshape((N,1,2))
/// * The methods [SOLVEPNP_DLS] and [SOLVEPNP_UPNP] cannot be used as the current implementations are
/// unstable and sometimes give completely wrong results. If you pass one of these two
/// flags, [SOLVEPNP_EPNP] method will be used instead.
/// * The minimum number of points is 4 in the general case. In the case of [SOLVEPNP_P3P] and [SOLVEPNP_AP3P]
/// methods, it is required to use exactly 4 points (the first 3 points are used to estimate all the solutions
/// of the P3P problem, the last one is used to retain the best solution that minimizes the reprojection error).
/// * With [SOLVEPNP_ITERATIVE] method and `useExtrinsicGuess=true`, the minimum number of points is 3 (3 points
/// are sufficient to compute a pose but there are up to 4 solutions). The initial solution should be close to the
/// global solution to converge.
/// * With [SOLVEPNP_IPPE] input points must be >= 4 and object points must be coplanar.
/// * With [SOLVEPNP_IPPE_SQUARE] this is a special case suitable for marker pose estimation.
/// Number of input points must be 4. Object points must be defined in the following order:
/// - point 0: [-squareLength / 2, squareLength / 2, 0]
/// - point 1: [ squareLength / 2, squareLength / 2, 0]

/// Calibrates a stereo camera set up. This function finds the intrinsic parameters

///
/// ## Parameters
/// * objectPoints: Vector of vectors of the calibration pattern points. The same structure as
/// in [calibrateCamera]. For each pattern view, both cameras need to see the same object
/// points. Therefore, objectPoints.size(), imagePoints1.size(), and imagePoints2.size() need to be
/// equal as well as objectPoints[i].size(), imagePoints1[i].size(), and imagePoints2[i].size() need to
/// be equal for each i.
/// * imagePoints1: Vector of vectors of the projections of the calibration pattern points,
/// observed by the first camera. The same structure as in [calibrateCamera].
/// * imagePoints2: Vector of vectors of the projections of the calibration pattern points,
/// observed by the second camera. The same structure as in [calibrateCamera].
/// * cameraMatrix1: Input/output camera intrinsic matrix for the first camera, the same as in
/// [calibrateCamera]. Furthermore, for the stereo case, additional flags may be used, see below.
/// * distCoeffs1: Input/output vector of distortion coefficients, the same as in
/// [calibrateCamera].
/// * cameraMatrix2: Input/output second camera intrinsic matrix for the second camera. See description for
/// cameraMatrix1.
/// * distCoeffs2: Input/output lens distortion coefficients for the second camera. See
/// description for distCoeffs1.
/// * imageSize: Size of the image used only to initialize the camera intrinsic matrices.
/// * R: Output rotation matrix. Together with the translation vector T, this matrix brings
/// points given in the first camera's coordinate system to points in the second camera's
/// coordinate system. In more technical terms, the tuple of R and T performs a change of basis
/// from the first camera's coordinate system to the second camera's coordinate system. Due to its
/// duality, this tuple is equivalent to the position of the first camera with respect to the
/// second camera coordinate system.
/// * T: Output translation vector, see description above.
/// * E: Output essential matrix.
/// * F: Output fundamental matrix.
/// * rvecs: Output vector of rotation vectors ( [Rodrigues] ) estimated for each pattern view in the
/// coordinate system of the first camera of the stereo pair (e.g. std::vector). More in detail, each
/// i-th rotation vector together with the corresponding i-th translation vector (see the next output parameter
/// description) brings the calibration pattern from the object coordinate space (in which object points are
/// specified) to the camera coordinate space of the first camera of the stereo pair. In more technical terms,
/// the tuple of the i-th rotation and translation vector performs a change of basis from object coordinate space
/// to camera coordinate space of the first camera of the stereo pair.
/// * tvecs: Output vector of translation vectors estimated for each pattern view, see parameter description
/// of previous output parameter ( rvecs ).
/// * perViewErrors: Output vector of the RMS re-projection error estimated for each pattern view.
/// * flags: Different flags that may be zero or a combination of the following values:
/// * [CALIB_FIX_INTRINSIC] Fix cameraMatrix? and distCoeffs? so that only R, T, E, and F
/// matrices are estimated.
/// * [CALIB_USE_INTRINSIC_GUESS] Optimize some or all of the intrinsic parameters
/// according to the specified flags. Initial values are provided by the user.
/// * [CALIB_USE_EXTRINSIC_GUESS] R and T contain valid initial values that are optimized further.
/// Otherwise R and T are initialized to the median value of the pattern views (each dimension separately).
/// * [CALIB_FIX_PRINCIPAL_POINT] Fix the principal points during the optimization.
/// * [CALIB_FIX_FOCAL_LENGTH] Fix  and  .
/// * [CALIB_FIX_ASPECT_RATIO] Optimize  . Fix the ratio 
/// .
/// * [CALIB_SAME_FOCAL_LENGTH] Enforce  and  .
/// * [CALIB_ZERO_TANGENT_DIST] Set tangential distortion coefficients for each camera to
/// zeros and fix there.
/// * [CALIB_FIX_K1],..., [CALIB_FIX_K6] Do not change the corresponding radial
/// distortion coefficient during the optimization. If [CALIB_USE_INTRINSIC_GUESS] is set,
/// the coefficient from the supplied distCoeffs matrix is used. Otherwise, it is set to 0.
/// * [CALIB_RATIONAL_MODEL] Enable coefficients k4, k5, and k6. To provide the backward
/// compatibility, this extra flag should be explicitly specified to make the calibration
/// function use the rational model and return 8 coefficients. If the flag is not set, the
/// function computes and returns only 5 distortion coefficients.
/// * [CALIB_THIN_PRISM_MODEL] Coefficients s1, s2, s3 and s4 are enabled. To provide the
/// backward compatibility, this extra flag should be explicitly specified to make the
/// calibration function use the thin prism model and return 12 coefficients. If the flag is not
/// set, the function computes and returns only 5 distortion coefficients.
/// * [CALIB_FIX_S1_S2_S3_S4] The thin prism distortion coefficients are not changed during
/// the optimization. If [CALIB_USE_INTRINSIC_GUESS] is set, the coefficient from the
/// supplied distCoeffs matrix is used. Otherwise, it is set to 0.
/// * [CALIB_TILTED_MODEL] Coefficients tauX and tauY are enabled. To provide the
/// backward compatibility, this extra flag should be explicitly specified to make the
/// calibration function use the tilted sensor model and return 14 coefficients. If the flag is not
/// set, the function computes and returns only 5 distortion coefficients.
/// * [CALIB_FIX_TAUX_TAUY] The coefficients of the tilted sensor model are not changed during
/// the optimization. If [CALIB_USE_INTRINSIC_GUESS] is set, the coefficient from the
/// supplied distCoeffs matrix is used. Otherwise, it is set to 0.
/// * criteria: Termination criteria for the iterative optimization algorithm.
///
/// The function estimates the transformation between two cameras making a stereo pair. If one computes
/// the poses of an object relative to the first camera and to the second camera,
/// ( , ) and (,), respectively, for a stereo camera where the
/// relative position and orientation between the two cameras are fixed, then those poses definitely
/// relate to each other. This means, if the relative position and orientation (,) of the
/// two cameras is known, it is possible to compute (,) when (,) is
/// given. This is what the described function does. It computes (,) such that:
///
/// 
/// 
///
/// Therefore, one can compute the coordinate representation of a 3D point for the second camera's
/// coordinate system when given the point's coordinate representation in the first camera's coordinate
/// system:
///
/// 
///
///
/// Optionally, it computes the essential matrix E:
///
/// 
///
/// where  are components of the translation vector  :  .
/// And the function can also compute the fundamental matrix F:
///
/// 
///
/// Besides the stereo-related information, the function can also perform a full calibration of each of
/// the two cameras. However, due to the high dimensionality of the parameter space and noise in the
/// input data, the function can diverge from the correct solution. If the intrinsic parameters can be
/// estimated with high accuracy for each of the cameras individually (for example, using
/// [calibrate_camera] ), you are recommended to do so and then pass [CALIB_FIX_INTRINSIC] flag to the
/// function along with the computed intrinsic parameters. Otherwise, if all the parameters are
/// estimated at once, it makes sense to restrict some parameters, for example, pass
/// [CALIB_SAME_FOCAL_LENGTH] and [CALIB_ZERO_TANGENT_DIST] flags, which is usually a
/// reasonable assumption.
///
/// Similarly to #calibrateCamera, the function minimizes the total re-projection error for all the
/// points in all the available views from both cameras. The function returns the final value of the
/// re-projection error.
///
/// ## Note
/// This alternative version of [stereo_calibrate_extended] function uses the following default values for its arguments:

/// * T: Translation vector from the coordinate system of the first camera to the second camera,
/// see [stereoCalibrate].
/// * R1: Output 3x3 rectification transform (rotation matrix) for the first camera. This matrix

/// * Q: Output  disparity-to-depth mapping matrix (see [reprojectImageTo3D]).
/// * flags: Operation flags that may be zero or [CALIB_ZERO_DISPARITY] . If the flag is set,

/// * alpha: Free scaling parameter. If it is -1 or absent, the function performs the default
/// scaling. Otherwise, the parameter should be between 0 and 1. alpha=0 means that the rectified

/// * newImageSize: New image resolution after rectification. The same size should be passed to
/// [init_undistort_rectify_map] (see the stereo_calib.cpp sample in OpenCV samples directory). When (0,0)
/// is passed (default), it is set to the original imageSize . Setting it to a larger value can help you

///
/// 
///
/// 
///
///
