We present a method of circular arc fragmented curve-fitting based on least mean-square error rule in this paper.
提出了一种基于最小均方误差准则的圆弧分段曲线拟合方法。
The fitting is verified with the mean square error of the calibrated and computed water(levels) and reasonable fitting is obtained.
用校正水位和计算水位的均方差检验拟合结果，结果表明拟合效果好。
