摘　　要：使用工业3D扫描仪,对某物体进行扫描,获得点云网格面后,导入CATIA逆向设计模块进行逆向设计,是一种常见的设计方法。在获得点云的过程中,由于工作环境、仪器、扫描对象等原因,获得的点云往往有缺陷,这就需要就有缺陷的点云部分进行修补,多截面法是一种常见的修补方法,实践证明,使用多截面法时连接曲线的张度设置是否合理,会严重影响逆向成果质量。It is a common design method to scan an object with industrial 3 D scanner,obtain point cloud mesh,and then import CATIA reverse design module for reverse design.In the process of obtaining point clouds,because of working environment,instruments,scanning objects and other reasons,the obtained point clouds are often defective,which requires the repair of defective point clouds.Multisection method is a common repair method.Practice has proved that the tension setting of connecting curves is reasonable when using multi-section method.It seriously affects the quality of reverse results.
