An algorithm of feature surface recognition based on quadric surface fitting and geometry property was presented. 摘要提出了基于二次曲面拟合误差分析和几何属性分析的特征曲面识别算法。
The method is suitable for computer programming and its calculation results are accurate.It fully unifies the asphericity calculation for conicoid and high-order aspheric surface. 该方法适于计算机编程，计算结果准确，且可完全统一二次曲面和高次非球面的非球面度计算。
