摘要
反向工程研究中,根据三维测量数据进行曲面重构是其关键技术之一。介绍了曲面曲率的基本理论,根据曲率精简点云的方法及曲率估算的方法,并结合实际对根据曲率精简测量点云数据的方法进行了改进,着重研究了邻域搜索、曲率估算、曲率精简原则等,在保证测量精度的前提下,在提高曲面重构的计算效率、减少存储空间等方面取得了较好的效果。
The Surface Reconstruction(SR) from 3D measured points cloud is one of the most important technologies in Reverse Engineering(RE). Based on curvature theory and curvature estimation, it introduces the method to reduce points cloud. This thinning method emphasizes on the algorithms for neighborhood searching, curvature estimate and thinning points cloud. The algorithms improve the caculation process, cut down the storage memory in SR.
