摘要
以实际工程为例,简要介绍了平面四参数法、布尔莎七参数法的优缺点及适用范围,并对这两种坐标转换方法的误差进行了分析,指出在平面坐标x,y上,采用布尔莎七参数法的精度相对较高。
Taking actual project as an example,this paper briefly introduced the advantages and disadvantages and applicable of plane four parameters methods,Boolean Sally seven parameters method,and analyzed the error of two kinds of coordinate conversion methods,pointed out that in plane coordinates x,y,the precision using Boolean Sally seven parameter method relatively high.
