摘要
根据车身外形曲面测量和拟合的要求，分析了散乱数据曲面拟合的Ｓｈｅｐａｒｄ、三角形剖分、Ｂ－ｓｐｌｉｎｅ最小二乘及Ｔａｙｌｏｒ逼近方法的各自特点，推导了计算模型并建立了软件系统。
Based on the requirements for measuring and fitting autobody surface, this paper analyses a variety of approximating algorithms including Shepard, trianglation, B spline least square method and Taylor. The paper also derives calculating models, in the meanwhile a software system is set up by using it. The samples of autobody surface design by the algorithm are given in the paper.
