基于三维实景的轨交应急联动可视化技术研究

摘要

随着城市的快速发展，轨道交通逐步成为应急联动管理工作的重点和难点。轨道交通的主体大部分位于地下，人流密集、空间狭窄，二维地图测绘难度大，三维建模技术难以实施应用。三维实景技术具有展示直观、采集数据快捷、建设周期短、成本较低等优势，在轨道交通的应急联动管理的可视化应用方面具有广阔的应用前景。本文以轨道交通为例，研究如何利用三维实景技术在应急联动管理中实现更好的可视化应用。%With the rapid development of city, the coalition emergency response in the subway system is becoming more and more important and complicated. Due to the features of subway system, such as underground, crowded and cramped, it is dififcult to measure 2D maps and deploy the 3D modeling techniques in the subway. The 3D virtual reality(Panorama) technique has the advantages on intuitive display, data collection, short-term construction cycle, and lower cost. Consequently, it can be applied in many visualization applications for the coalition emergency response in subway systems. This paper studies how to leverage the Panorama technique to realize more intuitive emergency response in the subway system.
