顾及测站点变形的数据处理方法

Data Processing Methods with Deformation of Stations

在基于测量机器人的多测站自动变形监测系统中,针对设在变形体上的测站点自身变形问题,提出了坐标转换技术的改正思想,探讨了几种基于坐标转换的变形监测数据处理方法。这些方法能够有效地消除或削弱测站点变形、气象条件等误差对监测结果的影响。最后通过模拟算例验证了三种数据处理方法的有效性,分析了它们的优缺点和适用条件。

In multi station automatic deformation monitoring system based on surveying robot, the self deformation of stations set on deformable body must be considered. According to such a problem, the coordinate conversion technology is proposed. And based on coordinate conversion, several data processing methods of deformation monitoring are discussed. Such methods can effectively eliminate or weaken the influences of station deformation and meteorological conditions to the monitoring results. At last, efficiency of three data processing methods is certificated by means of a simulation example. Their advantages and disadvantages and applicable conditions are also analyzed.
