【摘要】：海底管道是海洋油氣開(kāi)發(fā)的重要設(shè)施。隨著我國(guó)海洋油氣資源的開(kāi)發(fā),海底油氣管線已成為油氣集傳輸與儲(chǔ)運(yùn)系統(tǒng)的一個(gè)重要組成部分。海底管道的大規(guī)模鋪設(shè),一方面大大加快了各類資源的傳輸速度,同時(shí)也存在很多安全隱患。海底管道所處的海床環(huán)境或管線自身因素都有可能引起管線的斷裂,而一旦發(fā)生管線斷裂,不但修復(fù)難度大、費(fèi)用驚人,而且會(huì)造成嚴(yán)重的環(huán)境污染。因此,有效地監(jiān)測(cè)海底管道運(yùn)維狀況,確保海底管道安全穩(wěn)定運(yùn)行具有重要的現(xiàn)實(shí)意義與實(shí)際意義。在海底管道探測(cè)技術(shù)發(fā)展的基礎(chǔ)上,如何借助海底地形數(shù)據(jù)、地貌數(shù)據(jù),淺地層剖面數(shù)據(jù),海底管線空間位置數(shù)據(jù)、多媒體數(shù)據(jù)等海底管道檢測(cè)數(shù)據(jù),利用適合海底管道探測(cè)成果特征顯示的三維可視化技術(shù),實(shí)現(xiàn)海底管道三維動(dòng)態(tài)信息系統(tǒng)集成,已成為海底管道安全研究的熱點(diǎn)和難點(diǎn)。所以,需要構(gòu)建一套基于地理信息系統(tǒng)(Geographic Information System,GIS)與3D技術(shù)的海底管道三維動(dòng)態(tài)可視化信息集成系統(tǒng),實(shí)現(xiàn)主要管線分布區(qū)信息集成應(yīng)用與集成化決策支持管理,提高風(fēng)險(xiǎn)預(yù)警能力和應(yīng)對(duì)能力。本文提出了一種基于虛擬現(xiàn)實(shí)技術(shù)與Web Service的海底管道三維動(dòng)態(tài)可視化信息集成系統(tǒng)研究與設(shè)計(jì)方法。首先,運(yùn)用三角網(wǎng)生成算法與插值算法,并結(jié)合Unity3D游戲開(kāi)發(fā)引擎與ArcGIS地理信息系統(tǒng)軟件,將高程坐標(biāo)數(shù)據(jù)轉(zhuǎn)化為三維虛擬地形：然后,通過(guò)3ds Max與Photoshop制作三維可視化場(chǎng)景所需模型及其紋理,并利用Unity3D完成海底和海上場(chǎng)景的構(gòu)建及優(yōu)化；最后,提出一種基于空間坐標(biāo)轉(zhuǎn)換算法與Web Service的海底管道數(shù)據(jù)的可視化方法,實(shí)現(xiàn)管道數(shù)據(jù)的查詢、傳輸、解析與顯示。此外,本文選取合適的示范實(shí)驗(yàn)區(qū),并對(duì)該示范實(shí)驗(yàn)區(qū)進(jìn)行三維可視化系統(tǒng)構(gòu)建,以驗(yàn)證算法的正確性和設(shè)計(jì)方法可行性。對(duì)已構(gòu)建的系統(tǒng)進(jìn)行打包、發(fā)布,并通過(guò)服務(wù)器部署與測(cè)試主機(jī)測(cè)試,驗(yàn)證了系統(tǒng)的可靠性以及響應(yīng)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.
