摘 要：
In this paper, absolute arm measuring machine, and Reverse Polyworks software and 3D design software CATIA for automotive sheet metal parts are mixed for reverse design. Firstly, reverse engineering, scanning equipment and related software are briefly introduced. Secondly, the theory of surface reconstruction is briefly described, followed by a detailed description of the digital scanning of sheet metal parts, point cloud acquisition, point cloud processing, surface design and digital modeling. Finally,zebra analysis is used on the surface to evaluate the quality of the reconstructed surface.
