摘要
变形体的变形监测一直是测绘领域重点关注的项目,监测网中基准点的稳定是保证监测结果准确性的基础,针对变形监测中传统的基准点稳定性检测方式不准确的问题,对平均间隙法(Hannover-法)进行了深入分析与实验。通过matlab分别对2期监测数据进行整体检验和局部检验,判断出监测网中的不稳定点。结果显示,平均间隙法能通过整体检验判断整网中是否存在不稳定点,再通过分块间隙法具体判断出不稳定点位置,证明其在监测网基准点稳定性检验方面拥有良好的效果。
Deformation monitoring of deformation body has always been a key concern in the field of surveying and mapping. The stability of datum points in the monitoring network is the basis to ensure the accuracy of monitoring results. In view of the inaccuracy of traditional datum point stability detection methods in deformation monitoring, an in-depth analysis and experiment were carried out on theaverage clearance inspection method. Through MATLAB, the two periods of monitoring data were tested as a whole and locally, and the unstable points in the monitoring network were determined. The results show that the average gap method can judge whether there are unstable points in the whole network through the overall test, and then the position of the unstable points can also be judged through the block gap method, which proves that it has a good effect in the stability test of monitoring network benchmark.
