无人机倾斜摄影技术在矿山地质勘查中的应用

Application of UAV oblique photography technology in mine geological exploration

为准确捕捉矿山地质与环境情况,提出无人机倾斜摄影技术在矿山地质勘查中的应用。以河南省某石灰岩矿山区域作为研究对象,通过搭载四镜头倾斜相机的多旋翼无人机,采集研究区域的矿山地质数据。运用Photoscan软件处理矿山地质图像数据,生成密集点云以及研究区域地物剖面线。将剖面线导入3D Mine软件中,构建研究区域的三维模型,反映矿山地质情况与问题,实现矿山地质勘查。实验结果表明,该方法能够准确捕捉矿山地质与环境情况,且所勘查结果与实际环境结果吻合,勘查准确性较高。

In order to accurately capture the mine geological and environmental conditions,the application of UAV oblique photography technology in mine geological exploration was proposed.Taking a limestone mine area in Henan Province as the research object,a multi-rotor drone equipped with a four-lens tilt camera was used to collect the mine geological data in the research area.Use Photoscan software to process mine geological image data to generate dense point clouds and feature profile lines in the study area.Import the section line into the 3D Mine software to construct a 3D model of the study area,reflect the mine geological conditions and problems,and realize the mine geological exploration.The experimental results showed that the method can accurately capture the mine geological and environmental conditions,and the survey results were consistent with the actual environmental results,and the survey accuracy is high.
