| 摘 要： | 在分析NURBS曲线公式中基函数递归特征的基础上，提出了一种新的NURBS曲线插补算法。该算法通过前一个参数增量值和前一段插补弦长来确定下一个参数增量值，进而实现对参数的密化。仿真实验结果表明，该算法在改善弦长误差和减小计算量方面优于Taylor展开插补算法。

| Abstract: | Based on the recursive feature analysis of the base function in NURBS formula, a novel interpolation algorithm was put forwards. The method obtained the next parameter increment by a previous parameter increment and a previous chord length, and then the parameter interpolation was achieved.Simulation results show that, the proposed interpolation algorithm has obvious advantages in improving chord length errors and lessening computation load compared with those using Taylor's equation. |
