摘要
在建立OCS模型的基础上 ,利用二次NURBS曲面拟合法求解数据点的局部曲率 ,进而根据平均曲率半径的阀值识别各类边点 ,由边点连接形成封闭的边环 。
A sub\|surfaces segmentation method is presented, based on OCS model, using quadric NURBS surface fitting method to calculate local curvature, and then gain various edge points based on the threshold of even curvature. Edge\|neighborhood chain\|coding algorithm is used for forming boundary curves; finally gain a wire\|frame model of combined surface.
