Study of Automatic Monitoring Method of Similar Material Simulation Experiment Based on Close-range Photogrammetry

为了准确获取相似材料模型的变形数据,便捷地绘制良好的变形曲线,编写了一套相似材料模拟实验变形监测数据处理软件。主要功能包括监测点的自动识别与匹配、监测点坐标的获取与消除影像几何畸变平差、变形指标的计算与表达。使用该软件对中国辽宁南票矿区大窑沟煤矿某采煤工作面开采条件下煤层上覆岩层及地表变形与破坏相似材料模拟实验的变形数据进行获取与处理,根据监测数据分析了采空区影响下地表变形与破坏规律,取得了良好的应用效果。

In order to obtain deformation data precision of similar material model,favourable deformation curve could be plotted convenient and fast,so deformation monitoring data processing software of similar material simulation experiment was developed. It＇s function included monitoring point automatic identification and matched,monitoring point coordinate obtaining and eliminate image geometric distortion adjustment,deformation index count and express. Deformation data of similar material simulation experiment was obtained and disposed by the software,which is about overlying strata and surface deformation of coal seam under one coal mine working face mining of Dayaogou coal mine in Nanpiao coal mine area of Liaoning province of China,surface deformation and broken principle under goaf influence was analyzed by monitoring data,and obtained good application results.
