多已知点情况下坐标系之间的坐标转换

摘要

The issue of coordinate conversion between two reference frames is discussed in the paper on con-dition that the coordinates of many points are know n . 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 .%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。
