基于Multipath的煤矿巷道三维模型构建方法

3D Modeling Method of Mine Laneway Based on Multipath

针对现有煤矿巷道三维模型存在灵活性和可移植性差、数据更新维护困难等问题,提出了一种基于Multipath的煤矿巷道三维模型构建方法。该方法通过定义点弧拓扑数据模型,将煤矿CAD格式数据转换为Geodatabase中的要素类,利用开发的ArcGIS Engine程序、通过插入节点坐标生成巷道三维模型,实现了煤矿巷道自动建模,有效减少了巷道三维建模的工作量。

To solve problems of poor flexibility and portability and difficult update and maintenance of data in existing mine faneway 3D models, a 3D modeling method of mine laneway based on multipath was proposed. By defining point-polyline topological data model, the method can convert CAD format mine data to Geodatabase feature class, and uses developed ArcGIS Engine program and inserts node coordinate to create 3D mine laneway model, so as to realize automatic modeling of mine laneway, which effectively reduces working capacity of 3D laneway modeling.
