Hi,

I was following a page to use solvepnp with a fisheye model. However, the answer suggests using the same camera matrix for the last input of undistortPoints function. This last input corresponds to the camera matrix in the new or rectified frame. How can we consider this matrix to be the same as the original camera matrix?

Thanks!

Also, how can we use the rvec and tvec would correspond to undistorted corner points. Will this be the same as the rvec and tvec for the originally distorted image?

Thanks!
