Paper Abstract

This paper deals with the investigation of 3D-shape measurement techniques with respect to the calibration of the optical setup. It is shown that the accuracy of the measuring results depends on a high degree from the used geometric model and the calibration procedure. Rough approximations as generally used in practice will result in non neglectable systematic distortions of the measured 3D-coordinates. The relevance and practical ability of these theoretical investigations for optical shape measurement are demonstrated on an example of the fringe projection technique. The derived method can be used for other optical 3D- techniques too.
