摘要
选取Bursa-Wolf模型作为转换模型,采用QR矩阵求解模型转换参数,实现了坐标系转换算法;研发了北京54坐标数据向西安80坐标系统的转换工具。经检验,其转换误差相对精确、数值计算稳定性好。
Taking the Bursa-Wolf model as the translation model, this paper attempted to use QR matrix decomposition method for i guring out the model transformation parameters and compiles the algorithm of coordinate system conversion based on the method of object oriented programming. This paper analyzed the difference and relationship between Beijing geodetic coordinate system 1954 and Xian geodetic coordinate system 1980 in detail, and then discussed the necessity and feasibility of data conversion between the two geodetic coordinate systems.
