| Abstract: | 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. |
