废弃矿山生态环境修复中无人机倾斜摄影技术应用研究

Research on Application of UAV Tilt Photography Technology in Remediation of Ecological Environment in Abandoned Mines

为探索废弃矿山生态环境修复中无人机倾斜摄影技术应用的可行性和可靠性,以门头沟区某废弃矿山为例,利用无人机倾斜摄影技术,对研究区进行航空摄影测量,获得研究区三维实景模型、正射影像和地形图等目标成果,并通过实地测量等方式完成了对目标成果的质量检查验证。验证了无人机倾斜摄影技术在废弃矿山生态环境修复区域进行大比例尺测绘地形图方面的可行性与可靠性,同时结合三维实景模型实现替代野外踏勘、地形地物数据采集、土石方量计算等功能,社会效益和经济效益显著。研究成果可为废弃矿山生态环境修复治理提供技术支撑和方案参考。

In order to probe the feasibility and reliability of UAV tilt photography technology in remediation ecological environment of abandoned mines,we take an abandoned mine in the Mentougou district as an example,aerial photogrammetry is carried out in the study area by UAV tilt photography technology,and get a real-time 3D model,orthophoto,topographic map and other target results,and the quality inspection and verification of the target results are completed by means of field measurement.The feasibility and reliability of UAV tilt photography technology for large-scale topographic mapping in the ecological environment remediation area of abandoned mines are verified.At the same time,combined with the real-time 3D model,it can replace the functions of field survey,terrain and surface features data collection,earthwork volume calculation,and has significant social benefits and economic benefits.The research results can provide technical support and scheme reference for remediation of ecological environment of abandoned mines.
