Omnidirectional Camera Calibration Toolbox
This is a calibration toolbox for omnidirectional cameras which can be used with MATLAB. The most common omnidirectional camera models can be used for calibration and the toolbox has good corner extraction capabilities even for quite distorted omnidirectional images.
The toolbox is based on LIBOMNICAL.
This toolbox fixes some bugs, adds some additional features and was mainly used and tested with the Mei model. Therefore the other model implementations need probably some bug fixes too and everybody is welcome to contribute!
The idea is to have a general omnidirectional camera calibration toolbox for all the common models and a platform for future model implementations.
