Paper Abstract

The principle of projection structure light for 3D vision of small objects is described in this paper. Three vision systems, projection fringe, projection speckle and a special ring light illumination system, are introduced as the application of the principle. The ring light illumination system is specially designed for the 3D vision of small objects with specular surface like BGA balls. The testing result listed in the paper reveal that these methods can satisfy the requirements of 3D vision of small objects.
