【摘要】：长期的不合理开发与利用使得我国矿区环境问题尤为突出,对矿区进行动态监测可以有效减少矿业活动所带来的负面影响。传统的矿区环境监测多采用实地考察、逐级报告的工作方式,不但需要大量的人力、物力和时间,而且在发现问题时难以作出及时的反应,因此需要寻找一种能够满足当前矿区监测工作要求的方法。本文利用无人机获取矿区高空间分辨率影像来进行矿区开采的动态监测;获取的影像通过Agisoft Photo Scan Pro软件的SFM三维重建技术进行处理,实现了影像的快速拼接,以及高质量的数字高程模型(DEM)与数字正射影像图(DOM)的快速生成;最后利用Arc GIS软件的GIS方法得到不同时期的DEM高程变化情况及填挖方量,实现了矿区开采的动态监测。本次研究成果客观,可为矿区相关部门管理与规划矿区的开采现状提供有效的资料依据。
[Abstract]:The long-term unreasonable development and utilization make the environmental problems of mining areas in China particularly prominent. Dynamic monitoring of mining areas can effectively reduce the negative impact of mining activities. The traditional methods of monitoring the environment of mining areas are mostly field visits and report step by step. They not only require a great deal of manpower, material resources and time, but also are difficult to respond in a timely manner when problems are discovered. Therefore, it is necessary to find a method that can meet the requirements of current mine monitoring work. This paper uses UAV to obtain high spatial resolution image of mining area to carry on the dynamic monitoring of mining area, the acquired image is processed by Agisoft Photo scan Pro software SFM3D reconstruction technology, and the image can be spliced quickly. High quality digital elevation model (Dem) and digital orthophoto image (Dom) are generated quickly. Finally, the variation of Dem height and the amount of filling and digging in different periods are obtained by using Arc GIS software, which realizes the dynamic monitoring of mining in mining area. The research results are objective and can provide effective data basis for mining management and planning of mining area.
