Cali Cam is a stand alone camera calibration utility for linux. It aims to autonomously detect calibration points from multiple images and then recover the distortion coefficients, the intrinsic camera matrix, and for each calibration target the rotation and translation vectors. The calibration target is a checkerboard; the calibration points are the internal corners of the checkers. Calibration is performed according to the technique described by Zhengyou Zhang of Microsoft.
