Application and study of 3D alignment technology for the inspection of automobile punching parts

As for quality problems of automobile punching parts, an inspection method based on Geomagic reversing engineering software is established; basic principle thereof is scanning an automobile punching part by means of a photographic 3D scanner so as to acquire point cloud data and comparing processed point cloud data with standard digitalized samples by means of 3D alignment technology so as to acquire a processing error of the punching part.
