巷道自动成图及三维建模

Automatic mapping and 3D modeling on the roadway

针对矿山计算机自动绘制巷道工程图存在工作繁重、精度不高的现象,本文建立了基于矿山测量数据的巷道生成算法,实现了巷道的自动绘制与标注.在此基础上,采用分而治之算法及巷道轮廓线作为约束线段的方式建立了巷道Delaunay三角网,并生成了巷道表面模型.通过巷道顶、底板表面模型的剖分连接实现了矿山巷道三维立体建模.对比目前采用较多的巷道中心线加载巷道断面的三维建模方式,本文所提供的方法避免了巷道中心线不易提取、巷道断面变形、巷道转弯处难以平滑及复杂的巷道节点拓扑运算等问题,具有自动化程度高、容易实现等特点.
