由于测量存在观测误差,故根据测得的矩形地物特征点坐标数据,绘制的地物图形都不能严格是矩形,即地物直角条件不能严格成立。虽然目前的数字测图软件（如南方CASS 7.0）已提供了直角纠正功能,但它是一种简单机械的直角化方法,而不是进行平差纠正。为此,研究了一种以实际测量的地物特征点坐标为观测值进行地物直角平差纠正的算法,并以C#语言实现了该系统。实验证明,该系统能够更方便、更合理地实现对地物的直角纠正处理。

Due to the existing measuring observation error and thus the feature point coordinate of rectangular features, graphics arc not strictly the rectangular, which is that the fight conditions cannot be established. Although the current digital mapping software (such as the south CASS 7.0) has provided the fight angle correcting function, it is a kind of simple method and adjustment is not correct. Therefore a practical measurement of the feature point coordinates for ground observations is studied to correct the ground fea- ture fight angle adjustment, which is realized through the system C #. Experiments show that the system can achieve the right angle correction more easily and reasonably.
