摘　　要：针对因数字化误差或策略误差造成地物角点不是直角而需进行修正的问题,提出了一种基于AutoCAD的,既能保证地物角点正确直角化,又能保证纠正后顶点偏离原始顶点的坐标值尽可能小的高效算法。实践表明,该算法能够高效完成地物直角化的工作,简单易行,可满足实际生产需要。In order to solve the problem that the corner points of the features were not at right angles due to the digital error or the strategy error, we proposed an efficient method based on Auto CAD. This algorithm can ensure that the corner points of the features are correct and the coordinates of the corrected vertexes deviation the original vertex are as small as possible. The practice shows that the algorithm can realize the right angle of features efficiently, and meet the actual production needs.
