摘要
高程拟合是大地测量中经常遇到的问题,如何提高高程拟合的准确性是一项非常重要的任务。文中主要利用MATLAB作为工具进行校园GPS二次曲面高程拟合,采用最小二乘法拟合与稳健回归分析拟合两种方法,并对拟合结果进行精度评定和对比,验证了将稳健回归分析引入高程拟合是可以实现的。
Height fitting is a common problem in geodetic surveying.How to improve the accuracy of height fitting is a very important task.In this paper,MATLAB is mainly used as a tool for campus GPS quadric surface height fitting,and two methods of least square fitting and robust regression analysis fitting are adopted.Moreover,the accuracy evaluation and comparison of fitting results are carried out,verifying that it is feasible to introduce robust regression analysis into height fitting.
