摘要
基于盈亏修正的思想,提出迭代C-B-spline曲线的算法,来解决目前计算机辅助设计和逆向工程中急需解决的一个关键问题:无需求解方程组得到拟合(插值)给定点集的曲线。其基本思想是首先按给定的拟合点集作一条初始的C-B-spline曲线,然后用迭代公式逐次调整其控制顶点,得到一族拟合精度不断改善的C-B-spline曲线。
Based on adding and minusing ,this paper presents a fitting algorithm on iterative C-B-spline curves. It can settle key problems on fitting presented control points without solving any system of equations in CAD and reverse-engineering. At first, an original C-B-spline curves can be used to fit presented control points, then we can gain a precision C-B-spline curves by adjusting to presented control points gradually.
