Paper Abstract

Moire topography has been used as a noncontact method for grasping the 3D shapes of objects, but it is not easy to judge whether the surface is convex or concave from one moire picture. It is difficult for automatic measurement. In this paper, a new computer-based technique for automatic 3D shape measurement, tracking of carrier coded fringe pattern is proposed. It can accomplish fully automatic distinction between a depression and an elevation of the object shape. Therefore, it can accomplish automatic measurement. Validity of this proposal is experimentally verified.
