融合机载LiDAR与摄影测量技术在矿山迹地修复中的应用研究

Application and Research of the Fusion of Airborne LiDAR and Photogrammetry Technology in Mined-land Restoration

随着矿产资源的大力开发利用,出现一系列资源枯竭、环境污染、生态破坏的问题,使得矿山生态环境快速、有效的修复治理成为我国生态文明建设中重点关注的问题。然而,传统作业方法在环境恶劣的山区地形测绘中存在作业盲区多、难度大、成本高且安全隐患大等问题。因此,本文融合机载激光雷达和摄影测量技术从空中获取到矿山迹地完整、高精度的三维激光点云数据与高分辨率影像数据。再经过数据融合与后处理生成高精细数字高程模型以及各类专题图成果,在矿山迹地修复规划中林木资源调查、填挖方量计算、地形地貌变化分析及安全风险评估等各项工作中提供有力的技术与数据支持。

With the vigorous development and utilization of mineral resources,there are a series of problems such as resource depletion,environmental pollution and ecological destruction,which made the rapid and effective restoration and treatment of mine ecological environment become the focus of attention in the construction of ecological civilization in China.However,the traditional operation method has many problems,such as many blind areas,great difficulty,high cost and great potential safety hazard in the surveying and mapping of mountainous terrain in harsh environment.Therefore,this paper combined airborne lidar and photogrammetry technology to obtain complete and high-precision 3D laser point cloud data and high-resolution image data from the air to the mined-land.Then,through data fusion and post-processing,high-precision digital elevation model and various thematic map results are generated,which provide strong technical and data support for forest resource investigation,filling and excavation volume calculation,topography change analysis and safety risk assessment in mined-land restoration planning.
