无人机倾斜摄影技术在某露天矿山三维建模中的应用

Application of UAV Tilt Photography Technology in 3D Modeling of an Open-pit Mine

无人机倾斜摄影技术是一种前沿的矿山测量技术,目前处于快速发展阶段。通过对无人机倾斜摄影技术的发展背景、系统构成、技术原理和技术特点展开分析和研究,认为无人机倾斜摄影技术相比于传统的全站仪测绘技术具有真实、高效、灵活、应急性强等优点。海螺水泥某露天矿山采用无人机倾斜摄影技术,不仅实现三维模型的建立和满足矿山常规的测绘技术需求,还将航拍模型融合到矿山三维可视化管控平台当中,建成矿山智能决策支持系统,实现真实化的生产作业场景,对于推动露天矿山数字化建设具有重要意义。

The unmanned aerial vehicle(UAV)tilt photography technology is a cutting-edge mine surveying technology,which is currently in a rapid development stage.Through the analysis and research on the development background,system composition,technical principle and technical characteristics of UAV tilt photography technology,it is considered that compared with the traditional total station surveying and mapping technology,UAV tilt photography technology has the advantages of authenticity,high efficien⁃cy,flexibility and emergency response.An open-pit mine of Conch Cement adopts UAV tilt photography technology,which not only realizes the establishment of 3D model and meets the requirements of conven⁃tional surveying and mapping technology of the mine,but also integrates the aerial photography model into the 3D visual management and control platform of the mine,builds the intelligent decision support system of the mine,and realizes the realistic production and operation scene,which is of great significance for pro⁃moting the digital construction of open-pit mines.
