结合最小二乘法的基本原理,利用其进行道路平面曲线拟合,实例表明,与三次样条函数设计计算结果接近,同样能满足路线设计要求,且简化了计算过程,在平面设计工作中具有很强的实用性。
We analyzed the basic principle of least squares method,and used the method of least squares to fit the highway planar curve.The example shows that the results are close to ones by cubic spline function and meets the requirements of highway curve design.This method simplifies the calculation process,and is practicable in the work of curve design.
