| 2018-07-31 16:45:35 -0600 | marked best answer | Should one undistort each set of calibration images with camera calibration intrinsics before stereo calibration of a pair of cameras? Question is mostly stated in the title. I have pairs of calibration images, one from each camera. I run camera calibration on the detected chessboard corners in these images, once for the left camera and once for the right camera. Before stereocalibration, should I now undistort these images and remap the chessboard coordinates using the intrinsics learned from camera calibration? Would this improve the stereo calibration? |
