| 摘 要： | 经典最小二乘平差假定观测数据中不含有粗差,但随着现代测绘技术发展,数据采集的自动化程度越来越高,对数据采集过程进行人工干预较难实现,观测结果包含粗差在所难免。本文探讨利用拟准检定法进行粗差探测的原理、特点及优势,并通过模拟算例,验证了拟准检定法处理粗差的有效性。

| Abstract: | When the gross error is contained in the observed values,the least square estimation is not reliable.It is necessary to find some ways to deal with the gross errors.In this paper,the method of Quasi-accurate detection (QUAD) has been introduced to gross error processing.The results of the simulation example shows that QUAD is effective and feasible for gross error processing. |

| Keywords: | gross errors true errors quasi-accurate observations quasi-accurate detection |
