Abstract

A new method for fringe projection based 3D stereo scanners is introduced which realizes point correspondence finding and subsequent unwrapping of phase images without binary codes. The novelty of the method is the combination of geometric constraints between the three optical sensor components together with the estimated measurement accuracy of the system in order to achieve unique point correspondences. Considerable fringe code reduction obtained by use of geometric constraints and Gray code omission leads to a speed-up of the image sequence acquisition time. This opens the possibility to design moving sensors and to measure moving objects.
