How to get all reprojection errors from stereoCalibrate

edit

I need to get reprojection error for all images separately, not just the overall error from stereoCalibrate method. I was able to get these errors for single camera calibration by using projectPoints method and tvecs and rvecs returned by calibrateCamera method. Problem is that stereoCalibrate does not return mentioned rotation and translation vectors.

So is there a way how to obtain those errors? Or I have to write it by myself from scratch?
