this document of function cv::fisheye::initundistortrectifymap
i don't know r is. can help? thanks.
as stated in documentation!
r optional rectification transformation in object space (3x3 matrix). r1 or r2 , computed stereorectify can passed here. if matrix empty, identity transformation assumed. in cvinitundistortmap r assumed identity matrix.
it used in stereo camera calibration! if not using can pass empty matrix.
