论文摘要
采矿中的自动化需要现场的准确地图。由于开放地雷上的道路本质上是动态的，并且不断变化，因此手动更新路线图繁琐且容易出错。本文研究了使用现场运行的Haul Truck可用的GPS数据自动得出道路网络的准确表示的可能性。我们介绍了文献中提出的方法的概述，并测试了从现场运营的卡车收集的GPS数据的公开方法的性能。根据在所有测试算法中看到的缺点，开发了后处理步骤，该步骤几何分析了矿场上典型的自由驱动区域的文物的创建路线图，并显着提高了最终路线网络图的质量。
Automation in mining requires accurate maps of road networks on site. Because roads on open-cut mines are dynamic in nature and continuously changing, manually updating road maps is tedious and error-prone. This paper investigates the possibility of automatically deriving an accurate representation of the road network using GPS data available from haul trucks operating on site. We present an overview of approaches proposed in literature and test the performance of publicly available methods on GPS data collected from trucks operating on site. Based on shortcomings seen in all tested algorithms, a post-processing step is developed which geometrically analyses the created road map for artefacts typical of free-drive areas on mine sites and significantly improves the quality of the final road network graph.
