无人机在露天矿山监测中的应用

在露天矿山开采过程中，对矿山进行实时动态监测很有必要，它不仅能够实时掌握开采进度和开采方案实施的准确性，还有利于数字矿山建设。本文以河北省保定市涞源县某露天矿区为例，利用Pix4Dmapper软件对无人机航拍影像进行数据采集与处理，获取矿区的三维点云数据、数字正射影像和数字地表模型，并利用ArcGIS和Global Mapper软件对生产成果进行矿山开发占地分析，实现露天矿山三维可视化。本文为准确掌握矿山环境治理执行情况，把握矿山开发整体情况给予了有力的参考和借鉴作用。

Application of UAV in open-pit mine monitoring

In the process of open-pit mining, it is necessary to carry out real-time dynamic monitoring of the mine. It can not only grasp the real-time mining progress and the accuracy of mining scheme implementation, but also has a very important reference value for guiding the construction of digital mine. In this paper, taking an open-pit mining area in Laiyuan county, Baoding city, Hebei province as an example, Pix4Dmapper software is used to process the image taken by UAV, and obtain the orthophoto image, 3D point cloud and digital surface model of the mining area. At the same time, ArcGIS and Global Mapper software are used to analyze the production results of mine development and land occupation, so as to realize three-dimensional visualization of open-pit mine. It provides a powerful reference for grasping the implementation of mine environmental management and the overall situation of mine development.
