信息遥感技术倾斜摄影测量技术矿山测量中的应用

Application of information remote sensing technology in oblique photogrammetry in mining surveying

近年来,无人机倾斜摄影测量技术由于其高效率、高精度和低成本的优势,在矿山测量领域得到了广泛应用。这项技术基于无人机搭载的多视角相机设备,通过拍摄一定重叠度的图片,再运用光学原理与三维重建算法,生成矿区的精确地形与地貌模型。在测量过程中,数据采集的精度标准至关要,它直接影响最终结果的可靠性。无人机测量应用于矿区地形重建、开采区体积计算、斜坡稳定性分析、环境影响评估及后勘查阶段检测等多个方面。然而,要提升测量效率与应对复杂环境依旧是当前的主要研究方向。

In recent years,unmanned aerial vehicle(UAV)oblique photogrammetry technology has been widely used in the field of mining surveying due to its advantages of high efficiency,high accuracy,and low cost.This technology is based on a multi view camera device carried by drones,which captures images with a certain degree of overlap,and then uses optical principles and 3D reconstruction algorithms to generate accurate terrain and landform models of the mining area.The accuracy standard of data collection is crucial in the measurement process,as it directly affects the reliability of the final result.Drone measurement is applied in various aspects such as terrain reconstruction in mining areas,volume calculation of mining areas,slope stability analysis,environmental impact assessment,and post exploration stage detection.However,improving measurement efficiency and dealing with complex environments are still the main research directions at present.
