摘　　要：给出了三次参数样条曲线的一种基于离散曲率的自动光顺算法,通过离散曲率判断出曲线需要光顺的点并通过解决一个最优化问题对其进行光顺,本文的算法简单易行,计算量较小。An automatic faring algorithm for cubic parametric spline curves based on discrete curvature is presented. It judges points need to be faired by discrete curvature and faires them by solving optimization. It shows that it is simply facile and need do a smaller calculation.

关 键 词：三次参数样条曲线 光顺 离散曲率
