摘要: 针对井下巷道三维可视真实化的需求,根据井下巷道三维重构的拓扑结构,以及巷道中线和断面的基础数据,提出了基于离散点的不规则巷道断面三维快速重构算法,采用最短对角线和相邻轮廓线同步前进的协同策略,能够有效地逼近真实的巷道实体。仿真测试表明:该算法性能稳定,能够有效实现不规则断面的井下巷道的三维快速重构。

Abstract: In view of the request of 3D visualization on tunnel in underground,according to the topology structure of tunnels and the raw data of tunnels,a 3D reconstruction algorithm on irregular cross section tunnel based on discrete points was proposed.In this algorithm,a collaboration strategy of the shortest diagonal line and adjacent contour is adopted,which can effectively approach to the real tunnel entities.The simulation detection shows that this algorithm is stable in performance,and can effectively realize the 3D fast reconstruction of irregular cross section of underground tunnel.
