露采矿山三维可视化分析应用

Method of 3D visualization analysis on opencast mining

针对三维激光扫描技术在数字矿山中应用不足的现状,文章以实现露采矿山的三维可视化及空间分析为目标,研究了矿山点云TIN模型的建立方法及基于离散平均曲率的边折叠简化算法,得到了能快速流畅浏览且保留较多特征的矿山模型,最后给出了模型的基础空间分析功能的实现方法,并通过实验验证了算法的可行性。

Aiming at the current status of the less application of 3D laser scanning technique in the Digital Mining, the paper studied the building method of the mine point cloud TIN model and the simplifying algorithm of the edge collapse based on discrete：curvature, and got the mining model which could be browsed fast and smoothly with retaining more characteristics. Finally it gave the realization method of basic spatial analysis for the mine model. Experimental result proved the feasibility of the method.
