摘要
通过对多面函数正双曲面模型中的平滑因子进行分析,认为平滑因子的取值有一个最佳区间。取值在最佳区间内时,拟合精度较好;又通过对影响拟合精度的因素进行分析,得出求平滑因子的取值公式。通过实验验证,该公式的取值刚好在最佳区间内,且能取得较好的拟合精度。
Based in the analysis of muhi-quadric function, it is found that the value of the smooth factor should be in a perfect range for obtaining a higher fitting precision. If the value of smooth factor in the range, the fitting precision is good. The factor of the fitting precision is analyzed, then, the formula of the smooth factor is acquired. Through experiment texted, it＇ s proved that the value of the smooth factor just in the range and the fitting precision is perfect.
