无人机倾斜摄影测量技术在矿山测绘中的应用

The application of UAV tilt photogrammetry technology in mine surveying and mapping

无人机倾斜摄影测量技术具有精度高、成本低、成图快的优势,逐渐在现代化矿山测绘中的应用越来越广泛。本文实践结果表明:使用无人机倾斜摄影测量获得地形图与传统的全站仪测量结果相比较,二者所获地形图平面误差为5.2cm,高程注记点的误差为4.8cm,均满足相应比例尺精度基本要求,说明使用无人机倾斜摄影测量获得的大比例尺地形图精度可靠,并且减少了外业测绘工足量,提高了测绘效率,在现代化矿山测绘中应大力推广使用。

The uavor photogrammetry technology has the advantages of high precision,low cost and fast graph,and is gradually used more and more widely in modern mine surveying and mapping.The results of this paper show that the topographic map obtained by using the UAV tilt photogramage to obtain the topographic map and the traditional station measurement results,the topographic map plane error is 5.2cm,the elevation note point error is 4.8cm,both meet the basic requirements of the corresponding scale accuracy,It is shown that the accuracy of large-scale topographic maps obtained by using the UAV tilt photogrammetry is reliable,and the amount of field surveying and mapping is reduced,the efficiency of surveying and mapping is improved,and the use should be vigorously promoted in modern mine mapping.
