An accurate stereo vision system using cross-shaped target self-calibration method based on photogrammetry

This paper presents an accurate stereo vision system for industrial inspection, which uses a self-calibration method based on photogrammetry. A cross-shaped calibration pattern which is portable and easy to be manufactured is designed. The cross target can be used to calibrate stereo vision systems...
