         * is minimized. If the parameter method is set to the default value 0, the function uses all the point
         * pairs to compute an initial homography estimate with a simple least-squares scheme.
         *
         * However, if not all of the point pairs ( \(srcPoints_i\), \(dstPoints_i\) ) fit the rigid perspective
         * transformation (that is, there are some outliers), this initial estimate will be poor. In this case,
         * you can use one of the three robust methods. The methods RANSAC, LMeDS and RHO try many different
         * random subsets of the corresponding point pairs (of four pairs each, collinear pairs are discarded), estimate the homography matrix
         * using this subset and a simple least-squares algorithm, and then compute the quality/goodness of the
         * computed homography (which is the number of inliers for RANSAC or the least median re-projection error for
         * LMeDS). The best subset is then used to produce the initial estimate of the homography matrix and
         * the mask of inliers/outliers.
         *
         * Regardless of the method, robust or not, the computed homography matrix is refined further (using
         * inliers only in case of a robust method) with the Levenberg-Marquardt method to reduce the
         * re-projection error even more.
         *
         * The methods RANSAC and RHO can handle practically any ratio of outliers but need a threshold to
         * distinguish inliers from outliers. The method LMeDS does not need any threshold but it works
         * correctly only when there are more than 50% of inliers. Finally, if there are no outliers and the
         * noise is rather small, use the default method (method=0).
         *
         * The function is used to find initial intrinsic and extrinsic matrices. Homography matrix is
         * determined up to a scale. Thus, it is normalized so that \(h_{33}=1\). Note that whenever an \(H\) matrix

         *
         * is minimized. If the parameter method is set to the default value 0, the function uses all the point
         * pairs to compute an initial homography estimate with a simple least-squares scheme.
         *
         * However, if not all of the point pairs ( \(srcPoints_i\), \(dstPoints_i\) ) fit the rigid perspective
         * transformation (that is, there are some outliers), this initial estimate will be poor. In this case,
         * you can use one of the three robust methods. The methods RANSAC, LMeDS and RHO try many different
         * random subsets of the corresponding point pairs (of four pairs each, collinear pairs are discarded), estimate the homography matrix
         * using this subset and a simple least-squares algorithm, and then compute the quality/goodness of the
         * computed homography (which is the number of inliers for RANSAC or the least median re-projection error for
         * LMeDS). The best subset is then used to produce the initial estimate of the homography matrix and
         * the mask of inliers/outliers.
         *
         * Regardless of the method, robust or not, the computed homography matrix is refined further (using
         * inliers only in case of a robust method) with the Levenberg-Marquardt method to reduce the
         * re-projection error even more.
         *
         * The methods RANSAC and RHO can handle practically any ratio of outliers but need a threshold to
         * distinguish inliers from outliers. The method LMeDS does not need any threshold but it works
         * correctly only when there are more than 50% of inliers. Finally, if there are no outliers and the
         * noise is rather small, use the default method (method=0).
         *
         * The function is used to find initial intrinsic and extrinsic matrices. Homography matrix is
         * determined up to a scale. Thus, it is normalized so that \(h_{33}=1\). Note that whenever an \(H\) matrix
         * cannot be estimated, an empty one will be returned.

         *       If you are using Python:
         *   <ul>
         *     <li>
         *          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)
         *     </li>
         *     <li>
         *          The P3P algorithm requires image points to be in an array of shape (N,1,2) due
         *         to its calling of #undistortPoints (around line 75 of modules/calib3d/src/solvepnp.cpp version 2.4.9)
         *         which requires 2-channel information.
         *     </li>
         *     <li>
         *          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 REF: SOLVEPNP_DLS and REF: 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, REF: SOLVEPNP_EPNP method will be used instead.
         *   </li>
         *   <li>
         *       The minimum number of points is 4 in the general case. In the case of REF: SOLVEPNP_P3P and REF: 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).
         *   </li>
         *   <li>
         *       With REF: SOLVEPNP_ITERATIVE method and {code 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.
         *   </li>
         *   <li>
         *       With REF: SOLVEPNP_IPPE input points must be &gt;= 4 and object points must be coplanar.
         *   </li>
         *   <li>
         *       With REF: SOLVEPNP_IPPE_SQUARE this is a special case suitable for marker pose estimation.

         * transformation approximated by box filters being more robust to all sort of
         * noise, faster on larger images and is able to directly return the sub-pixel
         * position of the internal chessboard corners. The Method is based on the paper
         * CITE: duda2018 "Accurate Detection and Localization of Checkerboard Corners for
         * Calibration" demonstrating that the returned sub-pixel positions are more
         * accurate than the one returned by cornerSubPix allowing a precise camera
         * calibration for demanding applications.
         *
         * In the case, the flags REF: CALIB_CB_LARGER or REF: CALIB_CB_MARKER are given,
         * the result can be recovered from the optional meta array. Both flags are
         * helpful to use calibration patterns exceeding the field of view of the camera.
         * These oversized patterns allow more accurate calibrations as corners can be
         * utilized, which are as close as possible to the image borders.  For a
         * consistent coordinate system across all images, the optional marker (see image
         * below) can be used to move the origin of the board to the location where the
         * black circle is located.
         *
         * <b>Note:</b> The function requires a white boarder with roughly the same width as one
         * of the checkerboard fields around the whole board to improve the detection in
         * various environments. In addition, because of the localized radon
         * transformation it is beneficial to use round corners for the field corners
         * which are located on the outside of the board. The following figure illustrates
         * a sample checkerboard optimized for the detection. However, any other checkerboard
         * can be used as well.
         *
         * Use gen_pattern.py (REF: tutorial_camera_calibration_pattern) to create checkerboard.

         * The function estimates the transformation between two cameras making a stereo pair. If one computes

         * ( \(R_1\),\(T_1\) ) and (\(R_2\),\(T_2\)), 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 (\(R\),\(T\)) of the
         * two cameras is known, it is possible to compute (\(R_2\),\(T_2\)) when (\(R_1\),\(T_1\)) is
         * given. This is what the described function does. It computes (\(R\),\(T\)) such that:
         *
         * \(R_2=R R_1\)
         * \(T_2=R T_1 + T.\)
         *
         * Therefore, one can compute the coordinate representation of a 3D point for the second camera's

         *
         *
         * Optionally, it computes the essential matrix E:
         *
         * \(E= \vecthreethree{0}{-T_2}{T_1}{T_2}{0}{-T_0}{-T_1}{T_0}{0} R\)
         *
         * where \(T_i\) are components of the translation vector \(T\) : \(T=[T_0, T_1, T_2]^T\) .
         * And the function can also compute the fundamental matrix F:
         *
         * \(F = cameraMatrix2^{-T}\cdot E \cdot cameraMatrix1^{-1}\)
         *
         * 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
         * #calibrateCamera ), you are recommended to do so and then pass REF: CALIB_FIX_INTRINSIC flag to the

         *
         * Similarly to #calibrateCamera, the function minimizes the total re-projection error for all the

         * Calibrates a stereo camera set up. This function finds the intrinsic parameters
         * for each of the two cameras and the extrinsic parameters between the two cameras.
         *
         * param objectPoints Vector of vectors of the calibration pattern points. The same structure as
         * in REF: 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.
         * param imagePoints1 Vector of vectors of the projections of the calibration pattern points,
         * observed by the first camera. The same structure as in REF: calibrateCamera.
         * param imagePoints2 Vector of vectors of the projections of the calibration pattern points,
         * observed by the second camera. The same structure as in REF: calibrateCamera.
         * param cameraMatrix1 Input/output camera intrinsic matrix for the first camera, the same as in
         * REF: calibrateCamera. Furthermore, for the stereo case, additional flags may be used, see below.
         * param distCoeffs1 Input/output vector of distortion coefficients, the same as in
         * REF: calibrateCamera.
         * param cameraMatrix2 Input/output second camera intrinsic matrix for the second camera. See description for
         * cameraMatrix1.
         * param distCoeffs2 Input/output lens distortion coefficients for the second camera. See
         * description for distCoeffs1.
         * param imageSize Size of the image used only to initialize the camera intrinsic matrices.
         * param 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.
         * param T Output translation vector, see description above.
         * param E Output essential matrix.
         * param F Output fundamental matrix.
         * param rvecs Output vector of rotation vectors ( REF: Rodrigues ) estimated for each pattern view in the
         * coordinate system of the first camera of the stereo pair (e.g. std::vector&lt;cv::Mat&gt;). 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.
         * param tvecs Output vector of translation vectors estimated for each pattern view, see parameter description
         * of previous output parameter ( rvecs ).

         * 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,
         * ( \(R_1\),\(T_1\) ) and (\(R_2\),\(T_2\)), 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 (\(R\),\(T\)) of the
         * two cameras is known, it is possible to compute (\(R_2\),\(T_2\)) when (\(R_1\),\(T_1\)) is
         * given. This is what the described function does. It computes (\(R\),\(T\)) such that:
         *
         * \(R_2=R R_1\)
         * \(T_2=R T_1 + T.\)
         *
         * 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:
         *
         * \(\begin{bmatrix}
         * X_2 \\
         * Y_2 \\
         * Z_2 \\
         * 1
         * \end{bmatrix} = \begin{bmatrix}
         * R &amp; T \\
         * 0 &amp; 1
         * \end{bmatrix} \begin{bmatrix}
         * X_1 \\
         * Y_1 \\
         * Z_1 \\
         * 1
         * \end{bmatrix}.\)
         *
         *
         * Optionally, it computes the essential matrix E:
         *
         * \(E= \vecthreethree{0}{-T_2}{T_1}{T_2}{0}{-T_0}{-T_1}{T_0}{0} R\)
         *
         * where \(T_i\) are components of the translation vector \(T\) : \(T=[T_0, T_1, T_2]^T\) .
         * And the function can also compute the fundamental matrix F:
         *
         * \(F = cameraMatrix2^{-T}\cdot E \cdot cameraMatrix1^{-1}\)
         *
         * 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
         * #calibrateCamera ), you are recommended to do so and then pass REF: 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
         *  REF: CALIB_SAME_FOCAL_LENGTH and REF: 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.
         * return automatically generated
