Calibration of a video rasterstereographic system

Rasterstereography requires special methods of calibration in order to make use of the well-known photogrammetric procedures. The basic methods have already been published in previous papers. In the particular case of video rasterstereography, it is possible to collect the calibration data from a sequence of several video frames, provided that pixel-synchronous image digitization is used. By this technique, automatic image processing is considerably facilitated. In the present paper the procedures for recording and analyzing of the calibration images (using a control point system with changeable control planes) are described. Some results for a prototype system are presented
