为了获取自由曲面的精确外观特征，结合圆弧插值原理和质心定理的自组织特性，提出了一种自由曲面采样点的自适应规划策略，并提出了一种适合曲面数字化的求解算法。实验结果表明，自由曲面采样点的自适应规划算法简单。它弥补了基于圆弧插值的样本点分布缺陷，避免了求解复杂非线性方程时巨大的资源消耗。样本点可以根据表面外观特征进行很好的分布，并通过迭代找到所需规划精度下的样本点分布。
To acquire the precise appearance feature of free-form curved surface, an adaptive planning strategy for sample points of free-form curved surface, which combines the principle of circular interpolation and the self-organising characteristics of material centre theorem, is presented, and a solution algorithm suitable for surface digitising is proposed. The experimental results show that the adaptive planning algorithm for sample points of free-form curved surface is simple. It makes up the distribution defects of sample points based on circular interpolation, and avoids the enormous resource consumption in solving the complex non-linear equations. The sample points could distribute well according to the surface appearance characteristics, and the distribution of sample points under the required planning accuracy can be found via iteration.
