Cali Cam is being actively developed and has not yet reached a mature state. As such, distribution will be handled through svn. The source can be downloaded by issuing the following command:

svn co https://calicam.svn.sourceforge.net/svnroot/calicam calicam

More information can be found at the Sourceforge Site.

In addition to the source, Cali Cam requires OpenCV and the C++ Min Pack. Example calibration photos can be found at the MatLab Calibration Toolbox.
