摘要
为了能够准确高效地提高露天矿山环境综合治理勘查设计效率,解决常规勘查设计中高陡掌子面、渣堆、采坑等测量误差大的问题,提出了一种基于无人机遥感3D建模技术的勘查设计新方法。通过地面像控点结合无人机低空航拍矿山全貌,获取带GPS数据的全貌照片。在三维影像建模软件中生成基于三维点云模型的DOM、DEM等一系列成果后,将其导入到GIS和三维建模软件中。运用GIS的分析功能生成地形图、地形剖面图、坡度图、坡向图、挖填方、视域图等一系列成果,并将其应用到勘查设计中,可以大幅提高勘查设计精度和工作效率,丰富勘查设计成果。实现露天矿山综合治理的精细化设计,用工程可视化方法实现了工程设计由二维向三维的转变。通过A露天矿山的实际应用详细地介绍了该方法和主要技术成果,验证了其可靠性,但受无人机相机和飞行姿态等问题影响,该方法有待进一步研究。
In order to improve the efficiency of open air mine environmental comprehensive exploration,to solve the conventional exploration design constraints high steep,slag heap,mining measurement,this paper proposes a 3D modeling based on UAV remote sensing technology,a new method of exploration and design.The ground image control point is combined with low altitude aerial photos of the mine to obtain the full picture with GPS data.A series of achievements such as DOM and DEM based on 3D point cloud model,were achieved in 3D image modeling software.The achievements were imported into GIS and 3D modeling software.The analysis function of GIS is used to generate a series of results,such as topographic map,topographic profile,slope map,slope map,cut and fill,and visual field map.This exploration design can greatly improve the accuracy and efficiency of exploration design and exploration design.The refined design of the open air mine comprehensive treatment is realized,and the transformation of engineering design from 2D to 3D is realized by the method of engineering visualization.A practical application of open air mine was introduced in the method and the main technological achievements.But influenced by UAV camera and flight attitude,this method needs further study.
