摘　　要：在测量中,平面控制点的精度的评定具有重要的意义。文中以某一平面控制网点为例,求出了各待定点的误差椭圆参数,然后依据误差椭圆与误差曲线之间的几何关系,绘制了各待定点的误差曲线。实践证明,该方法容易实现,可操作性较强。In the measurement, the evaluation of the accuracy of plane control points had the great significance. In this paper, taking a certain plane control dot as an example, the error elliptical parameters of each fixed point were obtained. Then, according to the geometric relationship between the error ellipse and the error curve, the error curves of each fixed point were drawn. The practice showed that this method was easy to realize and the maneuverability was strong.

关 键 词：误差椭圆 误差曲线 平面控制点 坐标精度
