摘　　要：探讨了考虑公共点误差的坐标系转换方法,分析了转换结果在新坐标系下的精度变化,通过具体实例说明了该方法可行,从而为高精度测量的坐标系转换提供了理论依据。This paper probes into transformation between two different coordinate systems considering the common points error, analyses variation of precision for transformation, and proves the method is practical through a vivid example. Therefore, it provides theoretical argument for coordinate systems transformation in precise surveying.
