Hi, I want to use the function stereoRectify to get the Q matrix, but I don't know all the input parameters. How can I calculate the R and T parameters?

This is my calibration data:

Right camera:
camera_matrix: [634.909677387927, 0, 297.560249240374, 0, 634.865463121865, 158.8371760664, 0, 0, 1]

The R & T matrices are the rotation and translation between the two cameras. You can obtain them using StereoCalibrate. It's a similar procedure to the chessboard calibration used for a single camera, except you need to pass it images of the same scene taken by different cameras.
