全站仪坐标测量精度检定分析

摘要

随着高精度仪器的不断发展，如激光跟踪仪、激光扫描仪的发展，仪器厂家给出的仪器参数指标也开始发生变化，由此导致当前我们亟需一个统一的参数类型。就测量精度而言，给出仪器坐标测量精度是一个趋势。普通全站仪给出的是测角精度、测距精度，坐标测量精度却无法给定。据此，提出了通过基准距离测量比对、外符合精度评定、内符合精度评定的方法去评定全站仪坐标测量精度的方式。%With the development of surveying and mapping industry and the appearance of high precision instruments,such as the laser tracker,laser scanner,the instrument parameter index given by the instrument manufacturers are starting to change. Parameters index of various instruments are not the same,which urge us to unify all the parameter types.In terms of measurement precision,giving the coordinate measuring accuracy is a trend.But angle measuring accuracy and range accuracy are given by ordinary total station.So how to evaluate the coordinate measuring accuracy of them? It presents some methods of comparing the reference distance,assessing external accord accuracy,assessing internal accord accuracy,as a result achieve the goal of evaluate the coordinate measuring accuracy of total station.
