The paper discusses thin part inspection using three-dimensional (3D) non rigid registration. The main objective is to match measurement point data to its nominal representation, so as to identify form defects. Since form defects have the same size order as the thickness of the part, establishing such matching is a challenging task. The originality of the method developed in this paper is using a deformable iterative closet point algorithm (ICP), and integrating modal approach to express form defects. The method described improves the matching through iteration of the ICP and establishes a definition of the error. The results of the application show that the present method is efficient.
