I have the intrinsic parameters of fish-eye camera with fisheye model in opencv310 and I want to calculate the rotation vector and translation vector for arbitrary image using pose-from-N-points. As far as I know, the Python function, FindExtrinsicCameraParams2, could work, but it would require distortion coefficients p1 and p2 which are not returned from fish-eye calibration. What can I use for fish-eye p1 and p2 and what do they model?
