摘要
首先利用主曲率对网格进行粗分解,然后利用Gauss Ball+方法对每片子区域进行二次曲面的类型检测、细分解和重聚合,最后对细分的子网格区域中的二次曲面进行参数识别.实验结果表明,利用该方法可以自动、快速、准确地分解出零件中存在的二次曲面,可以很好地应用于逆向工程中二次曲面参数反求.
The mesh was first decomposed into multiple rough segments using principal curvature. Then based on Gauss Ball^＋ method, the algorithm detected the type of quadratic surface in each rough segment and sub-decomposed and re-clustered them. Finally it recognized each sub-decomposed meshes into quadratic surfaces. Results show that this method can quickly and automatically decompose quadratic surfaces from part, and can be well embedded into reverse engineering to recognize the parameters of quadratic surface.
