多项式拟合GPS水准高程软件设计与实现

Design and realization of GPS leveling height software with the polynomial fitting model

文中主要阐述了多项式高程拟合模型中的二次多项式拟合和三次多项式拟合。通过对这两种常用多项式拟合模型原理分析、算法过程的推导,精度评定方法的研究,基于Microsoft Visual C++6.0语言平台,进行多项式拟合模型程序开发。

This paper explains both quadratic and cubic polynomial fitting of polynomial fitting models. Besides, based on the analysis, the derivation of algorithm process and the research of accuracy assessment approaches of these two common polynomial fitting models, the paper mainly focuses on the development of the polynomial fitting model pro- grams based on Microsoft Visual C ＋＋ 6.0 platform.
