Jointly refines both cameras' intrinsics and distortion, the board poses and the right camera's relative pose (R, T) by LM (table).
> The detailed description below is the original text — the summary and the headings are translated.
Joint stereo calibration: both cameras' intrinsics and distortion, the board poses in the left camera and the right camera's pose relative to the left (X_right = R·X_left + T) are refined together by Levenberg-Marquardt on the reprojection error in both images. Each camera starts from camera_calibration_lm (or calib_left / calib_right if given) and (R, T) from the per-view relative poses (rotation by the chordal mean, translation by the mean). fix_intrinsics keeps both cameras' intrinsics and distortion fixed (OpenCV's CALIB_FIX_INTRINSIC).
