| 摘 要： | 针对坐标转换的问题提出一种基于最小二乘配置的改进方法,此方法与一般方法的最大区别是公共点坐标的误差,把转换参数作为非随机参数进行处理,并通过实验验证其可行性。实验结果表明此方法具有可行性,与一般方法相比,精度得到一定提高。

| Abstract: | Based on the least squares collocation,this paper put forward a method of plane coordinate transformation,which takes into the common point errors as random parameters,and transformation parameters as nonrandom parameters.Through the experimention,the result shows that this method was feasible and the precision can be improved. |
