利用IGES的人工骨三维结构生成过程中的数据转换

Estimation of normal and curvature based on point cloud data

为了解决人工骨三维结构生成过程中编程生成数据与CAD/CAM系统之间的数据转换问题,设计了基于初始化图形交换规范(IGES)的文件格式数据转换模块,实现了将程序所生成人工骨三维结构数据转换为标准数据格式的IGES文件,该文件可以被CAD/CAM系统正确读取。经过测试,几何数据转换完整,结果可靠。

In order to solve the problem of data transformation between the generated data in programming and CAD/CAM system during the spanning process of three dimensional artificial-bone structure,the data-transform module based on IGES file format is designed.Besides,the IGES file,the standard data format of which is the three dimensional artificial-bone structure data transform generated in programming,is realized,which can be correctly read off by the CAD/CAM system.The tests proves that the geometry data transform is intact with a valid result.
