On the basis of photogrammetry, a stereo vision system has been built for 3D profile measurement. It consists of two CCD cameras, a frame grabber and a personal computer. It will be extensively used in industrial inspection and robot vision, etc. In this paper the calibration of system, the measurement procedure of a 3D object, experimental results and the factors to affect the accuracy are discussed in detail. The stereo vision system needn't precise alignment of optical system and precise measurement of system's parameters in advance. It is suitable especially for the noncontact measurement of large scale objects with complex surface.
