摘　　要：讨论了多已知点情况下,两个坐标系之间的坐标转换问题。首先着眼于两个已知点的情况下,怎么去推导4个坐标转换参数及其中误差的计算公式,进一步给出多已知点情况下坐标转换参数平差值的计算公式。并介绍了使用c#语言编写坐标转换程序的编程思路和算例操作说明。The issue of coordinate conversion between two reference frames is discussed in the paper on con- dition that the coordinates of many points are known. First, the formulas on 4 piece of conversion parame- ters and their errors will have been deduced, if the coordinates of two points are known. Finally the formu- las about many known points will be shown. In the paper, the idea will be introduced that how to complete a program with c ~ language, and in the paper the author will show you how to use the program to solve a actual problem.
