备注

由于矿业开发强度高和规模大,以及在开矿过程里不注意维护好矿区的生态,目前矿区的生态维护承受着十分庞大的压力。为更好地对矿区进行生态修复,首先,本研究介绍矿区修复的基本内容及其效益,通过无人机像和三维激光扫描仪技术获取的航拍影像图和激光点云数据,阐述航拍影像与点云数据的获取流程和处理方式,将矿区生态修复采集的数据从二维拓展到三维;以矿区待修复区的测量分析和已修复区林地细化调查为案例,在 ArcGIS、南方 CASS、FAROscene和 GEOmagic等软件支持下,得矿区各类专题图和建立三维场景模型,为矿区生态修复提供技术和成果支撑。应用结果表明,航拍影像与点云数据在矿区生态修复中的应用,成效明显。

Due to the high mining development strength and scale, and in the process of mining don’t pay attention to the ecological safeguard mining area, the mining area ecological maintenance under enormous pressure.To better for the mining area ecological restoration, first of all, this paper introduces the basic content of mining area repair and benefit, by the unmanned aerial vehicle (UAV) and 3D laser scanner technology for aerial image and laser point cloud data, aerial images and the point cloud data acquisition process and approach, the data from the mining area ecological restoration from 2D to 3D;In the mining area to repair the measuring analysis and has been fixed area forest land detailed investigation for the case, such as ArcGIS, southern CASS, FAROscene and GEOmagic software support, mining area of thematic map and 3D scene model is set up, support for the mining area ecological restoration technology and achievements.Application results show that aerial images and point cloud data to the application of ecological restoration in mining area, effect obviously.
