摘　　要：汽车零部件和车身钣金件逆向设计中,为了减少三维模型与点云的误差、保证模型满足功能需求、提高设计模型的质量,提出了校正基准、点云分块、正逆向结合、阵列特征统一参数、以加工精度要求划分设计工作重心等方法,可降低建模工作的复杂度,减轻设计工作量,改进逆向设计模型的质量。In the reverse design of the automotive parts and BIW sheet metal parts, in order to reduce thedeviation between the 3D model and the cloud point and ensure the model to meet the functional require-ments, to improve the quality of the reverse design model, some methods were put forward, for adjustingreference, blocking cloud point, combining reverse engineering with forward engineering, normalizing theparameters of arrayed characters, distinguishing key points by machining accuracy. The methods can de-crease the complexity of the modelling, and reduce the design workload, and improve the quality of the re-verse design model.
