基于无人机低空遥感技术的矿山地形图测绘研究

Research on mine topographic map mapping based on UAV low altitude remote sensing technology

开采矿山是国家经济与科技实现高速发展的重要手段,而在开采矿山前要做的是对矿山的地形图进行测绘,是保证开采效率与开采的安全性、保护工作人员的人身安全以及施工设备的财产安全的重要手段,有利于开采工作的可持续进行。为了确保能够在矿山开采工作进行前对其地形有足够的了解,当前通常都选择使用无人机在矿山上空进行俯瞰的方式得到矿山地形图,其中低空遥感技术是近些年被开发出的实用技术,通过低空飞行的无人机近距离捕捉图像,得到相对具体的矿山地形图,有时还会在无人机上装载倾斜摄影系统,利用多个摄像机获得不同角度的画面,经过加工处理后可以得到立体感更强的地形图,对接下来的开采工作有更大帮助。

Mining is an important means to realize the high-speed development of national economy and science and technology.Before mining,it is necessary to map the topographic map of the mine,which is an important means to ensure the mining efficiency and safety,protect the personal safety of workers and the property safety of construction equipment,and is conducive to the sustainable development of mining.In order to ensure that the terrain of the mine can be fully understood before the mining work,the UAV is usually used to obtain the mine topographic map by overlooking the mine.Among them,the low altitude remote sensing technology is a practical technology developed in recent years.The relatively specific mine topographic map can be obtained by capturing images at a close distance by the UAV flying at a low altitude.Sometimes,the UAV is equipped with a tilt photography system,Multiple cameras are used to obtain images from different angles.After processing,a more three-dimensional topographic map can be obtained,which is more helpful to the next mining work.
