摘要
随着无人机航空摄影测量技术的快速发展,采用无人机技术的矿山测量已逐渐成为获取矿山地形数据的主要测量手段。针对小型消费级无人机具有机动灵活、操作简便、成本低、效率高的特点,该文介绍了大疆Phantom-4无人机在矿山地质环境恢复治理工程中的应用,并对其精度进行分析,主要研究不同像控点布设密度及像控点间距对测量精度的影响,以及利用数字正射影像图和三维点云数据对渣堆、危岩体等地貌进行了解译判读。通过与实测数据对比,结果表明,当像控点间距达到252m时就可以达到较高的检查点精度及渣堆、危岩体识别精度。
With the rapid development of UAV aerial photogrammetry technology,the mine survey by UAV technology has gradually become the main measurement means to obtain the mine terrain data.According to the advantages of small consumer UAV such as flexibility,simple operation,low cost and high efficiency,in this paper,the application of Dajiang Phantom-4 UAV in mine geological environment restoration and treatment project is introduced,and the accuracy is analysed.The influence on measurement accuracy by different image control point layout density and image control point spacing are mainly studied,and the landforms such as slag pile and dangerous rock is interpreted by using the digital orthophoto map and three-dimensional point cloud data.By comparing with the measured data,the results show that when the distance of image control points reaches 252 m,the higher inspection point accuracy and the slag pile and dangerous rock identification accuracy can be achieved.
