平面坐标转换模型的应用分析

Application Analysis of Plane Coordinate Transformation Model

文章针对当前较常用的几种平面坐标转换模型进行分析,结合具体算例,讨论了相似变换模型、二次曲面模型及内插模型等的转换精度。结果表明,当合理选择转换点时,二次曲面模型及内插模型能够获得相对较高精度的转换坐标。

This article analyzes several kinds of currently used plane coordinate transformation models.In addition,combined with concrete examples,it studies the conversion precision of similarity transformation models,quadric surface models and interpolation models.The results indicate that if a conversion point is reasonably chosen,quadric surface models and interpolation models can obtain the conversion coordinate with relatively high precision.
