摘要
作为误差来源的粗差,一般可以通过人为因素减少甚至消除。但随着采集数据的方法和处理数据的自动化,粗差有时不可避免,而粗差又不能在平差中消除,这将使平差精度降低甚至出现错误,所以粗差探测在数据处理中越来越重要。文中对粗差探测的方法作了应用研究比较,探讨了探测方法的适用范围。
As the source of the error, the gross error could be decreasing or exterminated by man-made factors. With the automation of the acquisition and dealing data, sometimes the gross error is inevitable and couldn＇t exterminated in error compensation, it would increase the error compensation accuracy, even error,so it is important to study the gross error detection in dealing data. This paper studys and compares different method of the gross error detection, and discusses the application area of the detection method.
