研究目的:目前,国内外对隧道监控信息管理系统的研究主要停留在二维视图下对监控数据简单的图表分析。少数系统虽在三维条件下实现了信息的查询,但隧道模型较为粗糙,信息单一。本文应用三维实时交互可视化信息技术研发了隧道监控信息平台,平台隧道模型精细,信息丰富。研究结论:(1)基于R—Trees构建的空间索引,可实现海量数据的高效管理;(2)研发的隧道工程监控三维实时交互可视化信息平台集隧道三维场景的快速构建、交互式漫游、信息查询于一体,场景浏览顺畅,信息丰富完整;(3)应用证明,该平台增强了用户在隧道监控中的可视化、交互性,可显著提高工作效率;(4)该研究成果可推广到铁路、公路、城市轨道交通、水利、矿山等工程建设领域的三维可视管理中。
Research purposes: At present, foreign and domestic study on information management system for tunnel engineering monitoring mainly remains in simple chart analysis of monitoring data under 2D view. A few system achieved information query under 3D condition, but the tunnel model is relatively rough and the information is single. In this paper, the technology of 3D real- time interactive visualization was apply to develop tunnel monitoring information platform where the tunnel model had almost real and rich information. Research conclusions: ( l ) Using R - Trees to create a spatial index can achieve an efficient management of huge amounts of data. (2) The tunnel engineering monitoring 3D real -time interactive visual information platform we studied combines building 3D scene of tunnel quickly, interactive roaming and information query into one. You can browse the scene smoothly, and the information is abundant and complete. (3) The practice proves that using the information platform can improve the visualization and interactivity of the tunnel monitoring for users, which greatly improves the work efficiency. (4)This research result can be applied to 3D visualization management of tunnel, railway, highway, urban rail transit and other engineering fields.
