摘　　要：由Tritop和Atos软件得到汽车车门点云数据,利用CATIA软件的数字编辑器和自由造型单元,对车门点云进行分网和曲面拟合处理,得到了车门曲面造型的结果.在处理过程中,运用了编辑点云、划界、过滤、分网、分区拟合和链接等一系列方法,得出了一些应用CATIA软件的经验和技巧.Utilizing the unit of Digitized Shape Editor and Freestyle in CATIA,Curved net map of feature lines and curved surface are created from the p oint clouds which is obtained with CCD Camera. Some methods are approached in th e process from delimiting boundary till to fitting surface.Some experiences and techniques are discussed through utilizing the methods of Editing, bracketing,fi ltering,dividing net, fitting, matching,etc.
