| 摘 要： | 根据扫描曲面的定义，本文提出了一种基于点云切片数据的扫描曲面特征的提取方法。首先，由平行且过扫描面特征的切片点云数据获取扫描轨迹曲线；接着，由垂直于扫描轨迹线的切片点云数据获得截面轮廓线；最后，由扫描轨迹曲线和截面轮廓线即可确定扫描面特征。本文算法已在UG／OPEN上实现，并用实例证明了该方法的正确性和可行性

| Abstract: | A method for extracting scanned surface features based on parallel cross section point cloud is presented,based on the definition of scanned surface.Firstly,the track curve of the scanned surface is extracted from the parallel section point cloud which is parallel to and includes the track curve.Secondly,the section curve is also extracted from the parallel section point cloud which is vertical with the track curve.Then a scanned surface is uniquely defined by the scanned track curve and the section curve.Experimental results illustrate the feasibility of the method. |
