How to convert a fish_eye image to a flat rectangular image?

Question

I am trying to reverse the fisheye lens effect, which means converting the fisheye image to a rectangular / square image using matlab for several weeks, but still without a good solution.

Basically, this is just an inversion. How can I realize the effect of a fisheye lens (barrel transformation) in MATLAB?

Can someone tell me how to do this?

You should look at the Jean-Yves Bouguet Camera Calibration Tool . If you have a camera, you can follow its steps to calibrate the camera yourself. Otherwise, you will need to learn something about the geometry of the lens.
