摘　　要：分析了现代测量技术中点云测量数据获取的局限性问题,运用UG软件的曲线曲面造型、分析、计算、查询等功能,通过UG软件的开发工具,直接调用UG软件内部函数,编写了"曲面点云仿真"、"曲线点云仿真"、"点云属性提取"等程序,仿真各种类型点云测量数据。经实践证明,所开发的仿真程序具有灵活、有效等特性,为测量精度分析、反求建模等相关技术研究提供一种新的思路和方法。The existing limited problems of point cloud data in modern measurement technology were analyzed, three programs ot ＂measurement simulation of surface point cloud＂, ＂measurement simulation of curve point cloud＂ and ＂extraction of point cloud attrib- ute＂ were written by directly calling internal functions of UG software, using the secondary development tools and some functions, such as modeling of curves and surfaces, analysis, calculation, inquiring and etc. The all kinds of measuring point cloud data were simula- ted. It is proven by experiments that the developed simulation program is flexible and effective, and a new thought and method for relat- ed techniques in measurement accuracy analysis and modeling in reverse engineering is offered.
