逆向工程中平面轮廓线数据的B样条曲面拟合

B-spline Surface Fitting for Plane Profile Data in Reverse Engineering

利用统计学的知识，对空间数据点参数值分布情况进行了分析，给出了曲面拟合过程中节点矢量的确定方法。在此基础上给出了平面轮廓线数据的B样条曲面拟合算法以及应用该方法对平面轮廓线扫描数据进行B样条曲面拟合的算例。

This paper analyzes the distribution of spatial points parameters on the basis of statistics theory, and presents the method of knot vector determination in the process of surface fitting. Based on the analysis, the algorithm of B-spline surface fitting for plane profile data is given. Finally, the method mentioned above is applied to surface skinning toward planar contour data points.
