| 摘 要： | 三维或二维坐标转换常采用相似变换，然而相似变换只能解决不同坐标系统之间定义上的差异，坐标系统局部形变系统性误差往往未能反应到转换模型中，因此本文试图从多种变换方法展开讨论，提出了采用相似变换与正形变换的理论解决坐标系统局部形变系统性误差，同时对选择模型参数提出了统计假设检验方法。最后得出一些有益的结论。

| Abstract: | Similar transformation is often used in three or two dimensional coordinate, but only it deal with coordinates definition difference between different coordinates systems, and systematic biases of local deformation is not reflected in coordinates transformation, so some transform methods are debated and local deformation biases are dealt with theories of Similar transform and conformal transformation. At same time, a statistical method is put forward to check model parameters. Finally a discussion of the experimental results and analysis are presented. Finally some concluding remarks are given. |
