Hong Yuan Zhang, Lei Bi, Hao Zhang · Applied Mechanics and Materials · 2011
For the automobile stamping parts quality inspection problem, this paper discusses the advantages and disadvantages of the contact measurement method and non-contact measurement method. It adopts non-contact photography-type scanner to obtain stamping parts point cloud, and compares and analyzes the automobile stamping parts point cloud and digital model based on ‘Geomagic-qualify’ software. In order to obtain accurate comparison result, it adopts alignment methods like benchmark feature surface, best fit, and RPS, etc. and finds out that RPS alignment method can obtain the values that are mostly approximate to the practically measured values.
