【摘要】：海底管道是海洋油气开发的重要设施。随着我国海洋油气资源的开发,海底油气管线已成为油气集传输与储运系统的一个重要组成部分。海底管道的大规模铺设,一方面大大加快了各类资源的传输速度,同时也存在很多安全隐患。海底管道所处的海床环境或管线自身因素都有可能引起管线的断裂,而一旦发生管线断裂,不但修复难度大、费用惊人,而且会造成严重的环境污染。因此,有效地监测海底管道运维状况,确保海底管道安全稳定运行具有重要的现实意义与实际意义。在海底管道探测技术发展的基础上,如何借助海底地形数据、地貌数据,浅地层剖面数据,海底管线空间位置数据、多媒体数据等海底管道检测数据,利用适合海底管道探测成果特征显示的三维可视化技术,实现海底管道三维动态信息系统集成,已成为海底管道安全研究的热点和难点。所以,需要构建一套基于地理信息系统(Geographic Information System,GIS)与3D技术的海底管道三维动态可视化信息集成系统,实现主要管线分布区信息集成应用与集成化决策支持管理,提高风险预警能力和应对能力。本文提出了一种基于虚拟现实技术与Web Service的海底管道三维动态可视化信息集成系统研究与设计方法。首先,运用三角网生成算法与插值算法,并结合Unity3D游戏开发引擎与ArcGIS地理信息系统软件,将高程坐标数据转化为三维虚拟地形：然后,通过3ds Max与Photoshop制作三维可视化场景所需模型及其纹理,并利用Unity3D完成海底和海上场景的构建及优化；最后,提出一种基于空间坐标转换算法与Web Service的海底管道数据的可视化方法,实现管道数据的查询、传输、解析与显示。此外,本文选取合适的示范实验区,并对该示范实验区进行三维可视化系统构建,以验证算法的正确性和设计方法可行性。对已构建的系统进行打包、发布,并通过服务器部署与测试主机测试,验证了系统的可靠性以及响应能力。
[Abstract]:Submarine pipeline is an important facility for offshore oil and gas development. With the development of offshore oil and gas resources in China, submarine oil and gas pipelines have become an important part of oil and gas collection, transmission and storage system. The large-scale laying of submarine pipeline, on the one hand, greatly speeds up the transmission speed of all kinds of resources, but also has a lot of hidden safety problems. The seabed environment or the pipeline itself may cause the pipeline to break, but once the pipeline breaks, it will not only be difficult to repair, the cost is staggering, but also will cause serious environmental pollution. Therefore, it is of practical and practical significance to effectively monitor the operation and maintenance of submarine pipelines and ensure the safe and stable operation of submarine pipelines. On the basis of the development of submarine pipeline detection technology, how to use submarine topographic data, geomorphological data, shallow stratum profile data, submarine pipeline spatial location data, multimedia data and other submarine pipeline detection data, etc. It has become a hot and difficult point to realize the integration of 3D dynamic information system of submarine pipeline by using the 3D visualization technology which is suitable for the characteristic display of submarine pipeline exploration results. Therefore, it is necessary to construct a 3D dynamic visualization information integration system of submarine pipeline based on (Geographic Information system GIS and 3D technology, to realize the application of information integration and integrated decision support management of main pipeline distribution area. Improve the ability of early warning and response to risk. This paper presents a research and design method of 3D dynamic visualization information integration system for submarine pipeline based on virtual reality technology and Web Service. First of all, using triangulation generation algorithm and interpolation algorithm, combined with Unity3D game development engine and ArcGIS GIS software, the elevation coordinate data is transformed into 3D virtual terrain: then, Making 3D visual scene model and its texture through 3ds Max and Photoshop, and using Unity3D to complete the construction and optimization of underwater and offshore scene. Finally, This paper presents a visualization method of submarine pipeline data based on spatial coordinate transformation algorithm and Web Service, which realizes the query, transmission, analysis and display of pipeline data. In addition, this paper selects the appropriate demonstration experimental area, and constructs the 3D visualization system to verify the correctness of the algorithm and the feasibility of the design method. The system was packaged and published, and the reliability and response ability of the system was verified by server deployment and test of host.
