基于点云和实景三维的矿坑岩壁表面测量

正在施工的矿坑除存在占地面积大、地形复杂多变等特点外,施测难度也十分巨大、存在安全隐患。本文利用无人机航空摄影和三维激光扫描相结合的技术手段,基于点云和实景三维模型对冰雪世界非拱角区矿坑覆绿岩壁现状进行表面测量,此法较传统方式更安全、更高效,测量成果精度更加可靠,为矿坑表面积及其他体征指标的测绘提供了一种有效的途径。

Surface Area Measurement of Mine Wall Based on Point Cloud and Real Scene 3D Model

In addition to the characteristics of large area and complex and changeable topography,the mine under construction is also very difficult to survey and has potential safety hazards.In this paper,using UAV aerial photography and three-dimensional laser scanning technology,based on point cloud and scene three-dimensional model,the surface area of the greenstone wall in the non-arch corner of the ice and snow world was measured.Compared with the traditional method,this method is safer,more efficient,and more reliable.It provides an effective way for surveying and mapping the surface area and other physical indicators of the mine.
