Hmmm... To be honest, I am not sure. If this project of yours is written in Managed C++, then I suggest that you try posting about your problem in the Managed C++ forum and see if someone looking there might be able to help you. Best wishes. John 3:16: "For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life."

If it's a true fisheye with 180 degree FOV, conversion to rectilinear would result in an infinite image. If you want to convert a segment cropped from the fisheye image, first you need to know the projection used by the lens. Equisolid angle and equidistant projections are the most common. You can get the projection equations from http://www.root.or.jp/fit/pages/gyogan_eng.htm[^] or http://www.lce.hut.fi/~jkannala/Kannala_Brandt_ICPR2004.pdf[^]. Then reverse the fisheye projection and apply the normal perspective projection instead.
