摘　　要：文章提出了一种三维雕刻曲面建模方法,按照相邻扫描层点数据的位置关系,将点云数据进行三角网格划分,并用单位法矢量方向的判别方法。从而生成CAD软件可接受的STL格式三维雕刻曲面模型,为CAM数控加工或者快速成型提供标准接口的源头CAD数据。The paper presents a method ot surlace mooelmg oI a three umte.~tu.aL ~UUtl.,~u＊ accordance with the relationship between the location of adjacent scanning layer of point data, point cloud data triangular mesh ,and discrimination method of the unit normal vector are used. Generated three dimensional carving surface model STL format acceptable to the CAD software. It is provide a standard interface for CAM and rapid prototyping.
