Abstract
A general scheme to validate the shape of a deformable part consists in performing a non-rigid alignment between measurements on the part’s surface with its CAD model. In many algorithms, this process requires the acquisition of a complete model of the inspected part, including regions near its fixation points. This paper proposes a system to perform inspection without the need to digitize the entire part’s surface or regions near fixation points. This algorithm uses instead of standard fixation points, surface feature points to compute the non-rigid transformation. Various tests on real parts show that a reduction of up to 58% of the RMS deviation in less than 3 iterations can be obtained using a single view of the part’s surface.
