【摘要】 提出了具有可行性的巷道模型实现方法,将巷道模型抽象为顶盘面、底盘面和侧面3部分。在获取巷道顶盘(或底盘)边界测量数据的条件下,提出了采用约束三角剖分的方法生成巷道模型的上下底盘面,利用两段成面法生成巷道模型的侧面,最后将这些面组合成巷道模型。该方法可以一次性地生成某一开采层面的全部巷道模型,并已成功地运用到以GeoView为平台的"数字紫金"项目中,取得了良好的效果。更多还原

【Abstract】 A feasible method of generating roadway model is put forward,in which roadway is abstracted into three parts: top plate surface,bottom plate surface and side surface,accessing the border measurement data of roadway’s top(or bottom) plate,the top(or bottom) plate surface can be generated using restriction triangulation,the side surface can be generated by the method of two segments forming surface,and finally roadway model can be generated by combination of these surfaces.All the mine roadways on a mining level can be generated at the same time by use of this method.And it has been successfully applied to the "Digital Zijin" project based on Geoview and good results were achieved.更多还原
