摘要: 以先后发生过两次大规模滑坡的中煤平朔公司东露天矿边坡为研究背景,利用三维激光扫描技术测绘速度快、测量精度高、数据量大的特点,对该露天矿边坡进行三维激光扫描,尤其是对发生过滑坡的两个重点区域进行精细扫描。基于综合改进ICP算法,将扫描得到的多站点云数据进行拼接处理,完成了长约2 km的露天矿边坡三维模型重建。研究结果表明,三维激光扫描结果符合工程实际特征,是一种快速建立矿山边坡数字模型的有效手段。

Abstract: With the background of an open-pit mine slope where two massive landslides happened, the open-pit mine slope was scanned with 3D laser scanner characterized by high mapping speed, high precision and large amount of data. The key areas were scanned especially where two landslides had happened. Based on the comprehensive improved ICP algorithm, the multi-station scanned cloud data were spliced to complete the 3d model reconstruction of the open-pit mine slope with the length of approximately 2 kilometers. The results of the study show that the 3D laser scanning result is consistent with the characteristics of actual engineering, is a fast and effective way of constructing digital model of open mine slope.
