在数字矿山系统中,为使错综复杂的地下巷道重建效果能达到矿山的验收标准,根据实测巷道交岔口轮廓线,采用分区(分块)建模思想,提出一种基于实测轮廓线的岔道口三维实体建模方法。将实测的岔道口轮廓数据按其特点分为顶底板和侧面轮廓线点集,采用凸包算法构造顶底板的简单多边形,并对其进行三角化。根据顶底板多边形顶点的先后顺序关系,建立侧面轮廓线的相邻关系,并采用连线框算法对相邻轮廓线进行三角化。实验结果表明,该方法简单有效,可解决任意断面形状、多个岔道口的建模问题,并且已经应用于DIMINE软件的测量插件中,效果良好。
在數字礦山繫統中,為使錯綜複雜的地下巷道重建效果能達到礦山的驗收標準,根據實測巷道交岔口輪廓線,採用分區(分塊)建模思想,提齣一種基于實測輪廓線的岔道口三維實體建模方法。將實測的岔道口輪廓數據按其特點分為頂底闆和側麵輪廓線點集,採用凸包算法構造頂底闆的簡單多邊形,併對其進行三角化。根據頂底闆多邊形頂點的先後順序關繫,建立側麵輪廓線的相鄰關繫,併採用連線框算法對相鄰輪廓線進行三角化。實驗結果錶明,該方法簡單有效,可解決任意斷麵形狀、多箇岔道口的建模問題,併且已經應用于DIMINE軟件的測量插件中,效果良好。

In the digital mine system,in order to make intricate underground roadway reconstruction effect reach the acceptance criteria of the mine,a 3D modeling method for fork entity based on measured contour using a partition or block modeling idea is proposed,which is is based on the measured contour of the roadway cross fork. The measured contour data of fork is classified by features into top,bottom and side contour point set. The convex hull algorithm is used to construct the roof and floor of a simple polygon, and triangulation. Based on the order of the top ( bottom ) plate polygon vertices,the adjacent relationship of the lateral broadside contours is established,and connection box algorithm is used to triangulate for adjacent contours. Experimental results show that,the algorithm is simple and effective and can solve any cross-sectional shape and any multiple fork modeling problems. The algorithm has been applied to the measurement plug-in contained in DIMINE software,and has good results.
