摘　　要：井下巷道的三维建模是实现数字化采矿非常重要的一个环节,论文利用数字图像处理技术根据摄像机拍摄的巷道断面照片对井下巷道进行三维重建。提出一种基于中心线-断面属性的局部建模方法。这种方法不考虑中心线之间的拓扑关系,对单一巷道和交岔点分别建模。该方法能实现平巷、斜坡道、竖井等地下工厂的三维实体建模,相比于现有的一些重建方法这种方法计算量小,能快速实现三维重建。The three-dimensional modeling of the underground tunnel digitize mining is a very important aspect. If this paper, using dig- ital image processing technology, based on roadway section photo camera, three-dimensional of the underground tunnel is reconstruced. Pro- posed a local modeling method based onthe eenterline-sectional properties. This method not consider the topological relationships between the centerline, modeling of a single roadway and crossing points, respectively. The way to achieve a three-dimensional solid modeling of the drift, ramps, shaft and underground factories, compared to the exisiting reconstruction methods, this method has a small amount of calcula- tion, and quickly realized three-dimensional reconstruction.
