Abstract

Stereo vision system based on the principle of triangulation has been built for shape inspection of technical object. It consists of two CCD-cameras, a He-Ne laser, a special electronic circuit and a personal computer. Here, we propose a method of non-coplane of every three calibration points and the optical center of camera to calibrate the system. By making some measures, we can improve the measurement accuracy greatly.
