Abstract

In moire methods and other full field measurement techniques suitable for robot vision it is often of key importance to be able to distinguish rigid body transformations from local deformations or defects. This is especially the case when using a computer generated surface as the reference(master). One solution is to maneuver the test object in space until the rigid body displacements are eliminated. This is however a very time consuming process. In this paper an algorithm is presented for automatic transformation in space ( 6 degrees of freedom ) of the computer generated surface. The aim is to position the master object in space such that maximum overlap between the master and the test object is achieved. Basically this system consists of an illumination unit a CCD camera a digital image processor and computer-generated master objects.
