| 摘 要： | 基于最小二乘法的平面相似变换对粗差的反映不灵敏、稳健性差.在平面相似变换的模型建立前,必须进行粗差探测,剔除存在粗差或等级较低的公共点.本文介绍了粗差的探测方法及应用实例.

| Abstract: | The plane similitude conversion,based on the least square method,is not sensitive to gross error and has worse stabilization.Before building the model of plane similitude conversion,we must detect the gross error to eliminate the public points with gross error or lower rank.This paper introduces the methods of gross error detection and its application. |
