    Application of image-free control UAV technology in mining topography survey

    • 摘要: 传统的无人机测量技术用于矿山测量须进行必要控制点的测设,也使无人机测设在复杂地形、难以进入等地区存在一定的应用瓶颈。免像控航测技术可以不提前布设控制点,成为矿山地貌形态调查的一种重要趋势。以昆明市某露天采矿区为研究区,利用DJI PHANTOM 4 RTK无人机进行航摄,分析免像控航测技术的关键技术和作业流程,完成了DOM(数字正摄模型)、DEM(数字高程模型)、DSM(数字栅格地图)和DLG(数字线划地图)制作、三维模型构建及模型内、外精度分析,对研究区地貌形态分布情况与特征参数进行分析统计。实验结果论证了免像控航测技术在矿山地貌景观调查中的可行性,为合理化开发矿产资源、最大化恢复生态环境提供技术支撑。

       

      Abstract: The traditional unmanned aerial vehicle survey technology used in mine survey must carry out the necessary control points measurement, which also makes the unmanned aerial vehicle survey in complex terrain, difficult to access and other areas has a certain application bottleneck.The image-free aerial survey technology is an important trend of mine landform survey, which needs not layout the control points in advance.Taking an open-pit mining area in Kunming City as the research area, this paper carries out aerial photography with DJI phantom 4 RTK UAV, analyzes the key technology and operation process of image free aerial survey technology, and then DOM, DEM, DSM and DLG production, three-dimensional model construction and model internal and external precision analysis are completed.The distribution of geomorphic form and characteristic parameters in the study area are analyzed and counted.The experimental results demonstrate the feasibility of image-free aerial survey technology in the investigation of mine landscape, and provide technical support for the rational development of mineral resources and the maximum restoration of ecological environment.
