This paper presents a new photogrammetric approach to automatically reconstruct and measure the imprecision or
deformations of metallic parts composed of curved edges. This approach uses images provided by a CCD camera
moving around the part. The main purpose of the approach is to reconstruct 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.
