摘要
近景摄影测量可以快速、自动地获取监测对象的点云数据,具有自动化程度高、劳动强度小等特点。本文在阐述Lensphoto多基线数字近景摄影测量系统的原理和监测流程基础上,采用该系统对矿区开采沉陷区进行变形监测,获取了沉陷区不同阶段的地表移动变形值。监测结果表明:近景摄影测量方法应用在矿区开采沉陷监测中是可行的,相对于全站仪测量,具有获取沉降数据丰富、生产效率高等特点。
Close-range photogrammetry can rapidly and automatically obtain the point cloud data of the monitoring object,with a high degree of automation,the intensity of labor force,etc.Firstly,the principle and the monitoring process of the multiple baseline digital close range photogrammetric system(Lensphoto)were introduced,then this system was applied to monitor the deformation of mining subsidence area.Finally,surface movement and deformation of subsidence area at different stages were obtained.The monitoring results show that close-range photogrammetry method applied to monitor the mining subsidence is feasible.
