Barrel distortion correction algorithm to correct FishEye lens - failing to implement with Java

Question

I have a large bulk of photographs taken with a fisheye lens. As I want to do some image-processing (e.g. edge detection) on the photos I want to remove the barrel distortio

Answer 1

I think your circles are caused by this line:

double srcYd = centerY + (diffX * factor);

which I'm guessing should be:

double srcYd = centerY + (diffY * factor);
