Paper Abstract

This paper presents a new photogrammetric approach to automatically reconstruct and measure the imprecision or deformations of metallic parts composed of curved edges and circular holes. This approach uses images provided by a CCD camera moving around the part. The main purpose of the approach is to reconstruct circular holes and curved edges automatically and accurately. For that, the solution uses data from the computer aided design model (CAD) and information extracted from the images. Experimental results on several parts present the precision and robustness of the process. They show that the proposed approach has a promising potential in automatic 3D control of industrial parts.
