A comparison on the CAD modeling system in typical reverse engineering

Point cloud processing,picking-up of features,reverse evaluation of curved-surface quality and influence analysis on followed-up engineering are several key links in the reverse reconstruction of CAD model.Currently the typical commercial reverse CAD modeling system can be divided as two kinds of the special purposed reverse software and the positive software that provides modules for reverse processing;these two soft-wares have their own features in the reconstruction of models.Taking the typical representatives Image-ware and Pro/Scan-tools of these two kinds of software as the target and aiming at the key links of reverse reconstruction of CAD model,this paper carried out rather detailed comparison and commentary on the features of these two soft-wares and carried out summary on these bases.
