Paper Abstract

A new technique is presented in this paper for gaging curvatures of industrial parts such as the panels of automobile bodies. This non-contact technique utilizes the projection of a grating upon the surface to be gaged. Implementation of the proposed technique is carried out with a digital image processor. Experimental results of applying the technique are presented.
