摘要
分析了B样条曲线的光顺拟合方法,针对按截面测量所得数据,将B样条曲线的光顺拟合方法拓展到B样条曲面的光顺拟合,该方法能够适应各截面曲线上数据点数的不同,方法简单、易行.给出了曲面拟合精度分析的数学模型,数值计算表明,该方法效率较高.
The fair fitting method with the least squares of the cubic B-spline curve has been analysed. For the given data points on the different sectional curves, the fair fitting method with the least squares of the bicubic B-spline surface is presented. This method is suitable for dealing with sectional curves with different measure data points, and can be used easily. The fitting precision of the B-spline surface is analysed. Numerical computation indicates that the efficiency of this method is higher.
