I get stereo rectify error after stereo camera calibration, the stereo rectified image looks like up-side down and left-side right.

Does anyone know this issue? Please help to solve, Thanks a lot.

most likely your calibratiion was bad. try again with better images, don't use a square chessboard

you might have to repeat it, until the rms error from calibrateCamera gets smaller than 0.5.
