【摘要】 为了实现基于切片数据的多孔复杂模型的三维实体重建,提出将基于轮廓线的局部优化方法与移动立方体(Marc-hing Cubes,MC)算法相结合,通过采用辅助轮廓法精确提取等值线,制定模型复杂程度的分类原则,合理选择配置方法,克服了多分支轮廓拓扑重构的困难,重建出由三角面片组成的三维形体表面模型。利用ANSYS参数化设计语言(AP-DL)在ANSYS中实现面模型向实体模型的转化,使重建后的模型不仅三维显示,还可直接用于有限元分析,使提出的三维重建方法具有更好的实用性。更多还原

【Abstract】 In order to reconstruct complex three-dimensional solid model with holes based on slice date,a new method is proposed,which integrates a local optimization approach based on contours and marching cubes.Through using the auxiliary contours method to enhance the accuracy of contours,constituting the classification principle by the complexity of the model,choosing and configuring methods reasonably,the difficulty of multi-branch contours topological reconstruction is overcomed.And a three-dimensional surface model formed by triangular patches is created.Furthermore,a solid model is constructed from the surface model by ANSYS Parameter Design Language(APDL)in the ANSYS software,which not only can be used for three-dimensional display,but also finite element analysis.Besides,it makes the three-dimensional reconstruction method more practical.更多还原
