Pipeline Network Patrol System Based on Mixed Reality

针对传统管网巡检系统中存在的管网数据时效性不足、管网间空间位置关系不直观、连贯性差等问题,本文采用混合现实、空间定位和三维建模等技术,针对管网巡检需要,动态构建管网并与实际地物进行融合,直观展现管网间的空间位置关系和管网的实时运行状态,设计并实现了基于混合现实的管网系统.针对管网模型定位问题,本文设计出了一种空间坐标转换方法来完成虚拟管网与真实管网的空间映射.针对管网模型的构建与优化问题,本文提出一种管网动态构建和优化方法实现管网动态加载和局部连接处的平滑处理.实验结果表明:通过文中提出的方法可以将虚拟模型与真实管网进行准确的空间融合,能够对虚拟管道衔接处进行平滑处理,清晰直观展现管道的空间关联关系.

For traditional pipeline inspection systems that exist non-sufficient timeliness in the network data,spatial location relationship between networks is not intuitive and with poor continuity problems,this study uses the mixed reality,3 D modeling,and spatial positioning technology,in accordance with the need of pipeline inspection,dynamically constructs the pipe network and fuses with the actual features,intuitively shows the spatial location relationship between the networks and the real-time running condition of the pipeline network,designs and implements pipe network system based on mixed reality.Aiming at the problem of pipeline network model positioning,this study designs a spatial coordinate transformation method to complete the spatial mapping between virtual pipeline network and real pipeline network.For the construction and optimization of pipeline network model,this study proposes a dynamic construction and optimization method to realize the dynamic loading of pipeline network and the smoothing of local connections.The experimental results show that the proposed method can accurately integrate the virtual model with the real pipeline network,smooth the connection of the virtual pipe,and clearly and intuitively show the spatial relation of the pipeline.
