基于点云数据的三维巷道快速建模研究

3D rapid modeling for tunnel based on point cloud data

基于三维激光扫描技术,进行精细巷道数据模型构建和精细巷道三维场景建立,研究由基本元素构建三维巷道空间模型的数据库组合法则,实现基本元素对象、巷道实体对象的动态快速构建。以某钼矿巷道建模实例验证了三维激光扫描技术用于巷道快速建模的可行性和技术优势。

Based on the 3D laser scanning technology,this paper constructs the data model of the fine tunnel,and further establishes the 3D scene.What is more,it researches the combination rule of the basic elements to construct the 3D tunnel space model database,and realizes the dynamic construction of 3D tunnel.Taken a molybdenum mine tunnel modeling as example,this paper verifies the advantages that the 3D laser scanning technology used into rapid modeling of tunnel.
