摘要
本文结合实际的桥梁工程采用6种模型进行高程异常拟合,并进行结果分析比较,结果显示:本例中多面函数拟合和移动曲面拟合表现出一定的优势,当拟合片区地势较平坦时,GPS高程拟合精度可以达到四等精度。
In this paper,combined with the actual bridge engineering by using 6kinds of model fitting height anomaly,analysis and comparison is made.Results showed that moving curved surface fitting and the polyhedral function fitting got better precision in the case.When the terrain is relatively flat,GPS elevation fitting precision can achieve four accuracy.
