摘要
提出一种改进的布尔沙转换模型——坐标系原点重心化的七参数模型,利用清华校园实测数据计算及模拟数据的对比分析,表明该方法明显优于普通的布尔沙坐标转换方法。
Considering the graph error and surveying error of common points centralized in a small region in solving unknown transformation parameters of Bursa model,an improved transformation model by moving the origin point of the coordinate system to the barycentre of the common points is introduced.The new method has been proved to be better than the traditional Bursa model by using real data and simulated results.
