【Abstract】 Based on the requirement of autobody surface measuring and fitting, this paper analyses a variety of approximation algorithms, including Shepard’s, Taylor’s and B-spline least" square method. A computing model is set up and a software package is developed accordingly. The samples of CAGD for autobody using the algorthm are also given in the paper.更多还原
