The CatPack toolbox is a Matlab software package for the calibration of Central Catadioptric Cameras using line images. It is particullarly useful for Parabolic sensors. The toolbox includes a GUI for selecting the line images, routines for calibration, and some functions for rectification of omnidirectional images and robust estimation of the conics corresponding to paracatadioptric projections of lines. 

 

The complete set of functions is available as a compressed file: CatPack for Matlab 7 and CatPack for Matlab 6.5
