Now I have got the inner parameters of fish-eye camera with fisheye model in opencv310 and want to calculate the rotation vector and translation vector for any image. As far as I know, the function, FindExtrinsicCameraParams2, may be competent for this work but there is a main issue that the distortion coefficients used in this function is [k1 k2 p1 p2], which is from Zhang's calibration method. This mean this function is not suitable fish-eye model in opencv310.

So is there any function similar with FindExtrinsicCameraParams2 to solve this problem?

Thank you very much!

Thank you very much!calibration. What can I use for fish-eye p1 and p2 and what do they model?
