无人机航空摄影测量技术在矿区地形测量中的应用研究

无人机摄影测量是中小面积地形测绘的重要手段,具有低成本、高效率、高精度、信息量大、产品可以重复使用的优点,弥补了传统方法的不足。本文简要介绍了无人机航空摄影测量技术,从工程实例中,进一步论述了利用无人机,搭载非量测型相机,在地形复杂的高山矿区进行地形测量的过程和方法,评估了点位精度误差,希望能为相关领域研究人员提供借鉴。

Application Research of UAV Aerial Photogrammetry Technology in Topographic Survey of Mining Area

Unmanned aerial vehicle photogrammetry is an important means of small and medium area topographic mapping.It has the advantages of low cost,high efficiency,high precision,large amount of information,product reusability,and makes up for the shortcomings of traditional methods.This paper briefly intraduct the aerial photogrammetry technology of UAV.From the engineering example,the process and method of topographic surveying with UAV and non-metric camera in the complex topographic Alpine mining area are further discussed,and the point accuracy error is evaluated,hoping to provide reference for researchers in related fields.
