In order to build a three-dimensional ( 3D) face contour precisely, a3D model method of in-verse identification is presented based on laser scanning and CAD/ CAM technology. 首先采用激光扫描系统对人脸进行扫描,然后利用采集的点云数据,通过计算机辅助设计与制造(CAD/CAM)中的反求工程方法,建立面部三维曲面模型。
At the same time, the transformation from the solid model to the face model is explored. Thus, the integration of CAD/ CAE/ CAM is realized. 同时对从体模型向面模型的转换进行了探索,从而实现了CAD/CAE/CAM一体化集成。
