摘　　要：坐标系统转换的传统方法没有顾及控制点在原坐标系统中的观测误差。为了克服这一不利因素,顾及观测误差对坐标系统转换的影响,本文提出应用总体最小二乘算法实现平面坐标系统转换。用实测数据验证总体最小二乘算法实现平面坐标系统转换的可行性,并与传统的最小二乘模型进行比较,证明了方法的有效性。Traditional coordinate system transformation methods do not consider the observation error of control points in the original coordinate system. To consider the observation error which has an affect on the coordinate system transformation, the paper applied Total Least Squares（TLS）to achieve plane coordinate system conversion. Measured data were applied to test the feasibility of the meth- od in plane coordinate system conversion, and comparison with traditional Least Squares （IS） was carried out finally. The result veri- fied the effectiveness of the proposed method.
