+@param K2 Second camera intrinsic matrix.
+@param D2 Second camera distortion parameters.
+@param imageSize Size of the image used for stereo calibration.
+@param R Rotation matrix between the coordinate systems of the first and the second
+cameras.
+@param tvec Translation vector between coordinate systems of the cameras.
+@param R1 Output 3x3 rectification transform (rotation matrix) for the first camera.
+@param R2 Output 3x3 rectification transform (rotation matrix) for the second camera.
+@param P1 Output 3x4 projection matrix in the new (rectified) coordinate systems for the first
+camera.
+@param P2 Output 3x4 projection matrix in the new (rectified) coordinate systems for the second
+camera.
+@param Q Output \f$4 \times 4\f$ disparity-to-depth mapping matrix (see reprojectImageTo3D ).
+@param flags Operation flags that may be zero or @ref CALIB_ZERO_DISPARITY . If the flag is set,
+the function makes the principal points of each camera have the same pixel coordinates in the
+rectified views. And if the flag is not set, the function may still shift the images in the
+horizontal or vertical direction (depending on the orientation of epipolar lines) to maximize the
+useful image area.
+@param newImageSize New image resolution after rectification. The same size should be passed to
+#initUndistortRectifyMap (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 larger value can help you
+preserve details in the original image, especially when there is a big radial distortion.
+@param balance Sets the new focal length in range between the min focal length and the max focal
+length. Balance is in range of [0, 1].
+@param fov_scale Divisor for new focal length.
