近景摄影测量在矿山尾矿库干滩监测中的应用

Application of Close-range Photogrammetry in Dry Beach of Tailings Pond Monitoring

近景摄影测量法应用于矿山尾矿库干滩监测,通过布设若干像控点和2台网络摄像机,并提供可靠的通讯、供电、显示设备,组成干滩在线监测系统。借助软件对立体影像进行线、面特征的提取与识别,对立体影像进行自动匹配。根据特征提取和影像匹配结果,在立体影像上进行目标点自动量测和定位,获得干滩参数量测结果。结合实例进行数据处理和精度对比分析,结果表明,该方法在干滩自动化监测中具有较好的应用前景。

Close-range photogrammetry method is applied to monitor the dry beach of mine tailing pond. The dry beach online monitoring system includes some control points, two network cameras ann oevices of communication, power supply and display. The stereo images are matched by extracting and identifying the line and surface-based features of stereo images by means of software. According to the features extracting and images matching results, the targets of stereo images are measured and positioned automatically to obtain the the parameters of dry beach. Combined with practical application, the measurement data are processed and measurement accuracy are analyzed. The research results show that, close-range photogrammetry method has a good prospect in monitoring dry beach of tailings.
