实测导线数据的巷道系统三维自动建模方法

An automatic 3D entity modeling method for laneway system based on measured wire data

针对现有巷道建模方法中存在的岔道口处模型不平滑或不连通,以及模型难以达到工程验收标准的问题,提出一种基于实测数据的巷道系统三维自动建模方法。根据实测导线中的定位数据特点,采用红黑树存储定位数据,实现巷道系统关联数据的分层快速搜索;由测点数据生成中心线,保证巷道模型能够有效反映工程的实际情况;对交岔口处模型进行布尔运算,实现巷道间的平滑连通。采用VS2008和HOOPS可视化工具包实现该方法,实验结果表明该方法能够快速重构出地下巷道三维模型,为矿山巷道工程验收等提供准确的数据来源。

In order to solve the problem that cross sections were not smooth or not connection,and the problem of laneway model couldn＇t satisfy the requirement of laneway engineering acceptance,this paper proposed an automatic 3D modeling method for laneway system based on measured data.According to the characteristics of the location data in measured wire,adopted the red-black tree to store the location data,and realized the hierarchical search algorithm for laneway related data;centerline data generated by the measuring point,this ensured laneway model could effectively reflect the actual situation of the project;made boolean operations for the cross section,realized the smooth connection with each other between laneway.The paper created the mine laneway modeling by using VS2008 and HOOPS Visualization Toolkit to realize the method.The results witness that this method can quickly reconstruct the 3D model of underground laneway,provide accurate data source for the mine laneway project inspection.
