Fisheye --> Undistorted --> Fisheye

asked 2020-10-06 08:53:59 -0500

Hi all, this is my first question on this forum!

I calculated the intrinsic and extrinsic parameters for my fisheye camera by the calibration script found here by which I undistort my fisheye image. However, I cannot find any information on how to transform my undistorted image back to fisheye. No such operation is available under the geometric image transformations. Any ideas on how this can be done?

can you explain, what you need it for ?

I want to transform it to rectilinear so that I can generate a grid describing distances in it by straight lines. I then want to back transform it back so that I can apply the grid to my fisheye image.
