由于受到自然界、仪器、人为等一些因素的影响,观测数据中不但存在偶然误差而且还存在着由这些因素引起的粗差。因此,对观测数据进行认真检测,定位并修正粗差观测,以提高参数估计的准确度和精度,一直是测绘工程领域的热点问题。本文对粗差探测进行了简要概述,同时详细地介绍了三种粗差探测方法。

There are not only accidental errors,but also many gross errors in the observational data because of nature,instrument and human error.So it has become a hot issue in the field of surveying major to detect and corrct the obveration data seriously in order to improve the accuracy rating and precision of parameter.This paper introduces the gross errors and there methods to deal with the gross errors.
