摘要
为了实现在水利工程中不同坐标系坐标的自由转换,基于布尔沙模型的三维空间直角坐标转换的基本原理,分析通过改变某些精度较低的公共点坐标权值,采用间接平差法达到了高精度坐标转换,并以实例进行验证,结果表明:其成果可用于水利工程中不同参考椭球面的坐标转换。
According to the basic principle of three-dimensional space rectangular coordinate conversion based on the Bursa-Wolf model, the author analyzed the method for conversion between different coordinate systems of hy- draulic engineering. Coordinate conversion of high accuracy is feasible by modifying the weights of some public points＇ coordinate with low accuracy and adopting indirect adjustment method. Practice example was also presented to prove this method can be appliod in coordinate conversion between different reference ellipsoid of hydraulic engineering.
