Three-dimensional Real Scene Data Acquisition and Modeling of Surface and Underground Geographic Environment in High Altitude Mining Area

本文介绍了地表和井下三维实景建模的技术手段和方法,针对高海拔矿区地表和井下三维实景信息采集与建模方法和流程进行了研究,详细论述了地表和井下实景三维数据采集预处理流程,采用无人机倾斜摄影技术对矿山地表环境进行航空摄影,完成航摄区域三维模型构建。使用国际先进的SLAM移动三维测量技术,对复杂的矿山地下空间快速地进行三维空间移动扫描,并得到基于点云的真三维空间数据。通过控制测量手段将地表和井下三维数据进行融合,得到矿区整体三维实景模型。

This article introduces the technical means and methods of surface and underground Three-dimensional real scene modeling,researches on the methods and processes of surface and underground Three-dimensional real scene information acquisition and modeling in high-altitude mining areas,and discusses in detail the preprocessing process of surface and underground real scene Three-dimensional data acquisition,Using drone tilt photography technology to carry out aerial photography of the mine surface environment,and complete the construction of a three-dimensional model of the aerial photography area.Using the international advanced simultaneous localization and mapping mobile Three-dimensional measurement technology,the complex underground space of the mine is quickly scanned in Three-dimensional space,and the true Three-dimensional space data based on the point cloud is obtained.The three-dimensional data of the surface and underground are merged by controlling the measurement method to obtain the overall three-dimensional real scene model of the mining area.
