坐标转换抗差模型分析与应用

Robust model analysis and application of Coordinate transformation

中文摘要英文摘要

本文采用莫洛金斯基模型进行空间坐标转换,对实例使用抗差最小二乘估计(以下简称抗差估计)和最小二乘估计(LS)分别进行估计,得出抗差估计值在精度和可靠性上较最小二乘估计值均有明显的优越性。最后,本文强调坐标转换方法仍需大量的研究,满足大范围高精度坐标转换的格网法需要得到重视和推广。

In this paper,the application of Morrow Kinski model in space coordinate conversion is introduced. It adopts robust least squares estimation and the least-squares estimation for practical instance respectively. It find that the value obtained with the robust estimation accuracy and reliability have obvious advantages than the least squares estimates. Finally, the paper emphasizes the coordinate transformation method still needs a lot of research. The grid method of fulfilling coordinate conversion with wide range and high-precision requires attention and promotion.
