【摘要】：二三維一體的、基于互聯(lián)網(wǎng)的多源歷史空間數(shù)據(jù)展示平臺目前并不完善,如何實現(xiàn)一個能通過Web端瀏覽訪問的、展示多源歷史空間信息的平臺是主要目標(biāo)。論文就其設(shè)計出發(fā),對其中一些關(guān)鍵技術(shù)進(jìn)行了研究,并通過實例進(jìn)行了驗證。通過不同歷史時期影像數(shù)據(jù)的疊加展示城市歷史變遷,并引入三維模型的發(fā)布,直觀逼真地展示歷史建筑詳細(xì)信息,并在此基礎(chǔ)上實現(xiàn)用戶自定義檢索、路徑分析等實用功能,由于數(shù)據(jù)的多源特性,實現(xiàn)起來存在很多困難。展示歷史變遷需要大量的高分辨率影像數(shù)據(jù),對其進(jìn)行瓦片裁剪時級數(shù)要求高,導(dǎo)致裁剪速度慢;多源數(shù)據(jù)包括影像數(shù)據(jù)、矢量數(shù)據(jù)及模型數(shù)據(jù),多種類型數(shù)據(jù)的存儲及調(diào)用也較為復(fù)雜;影像數(shù)據(jù)只具有位置信息,不具備屬性信息,無法與興趣點(Point of interest)產(chǎn)生關(guān)聯(lián),因此無法直接進(jìn)行興趣點的檢索;由外部軟件創(chuàng)建的三維模型不具備空間屬性信息,無法準(zhǔn)確定位發(fā)布。此外,所有的數(shù)據(jù)均通過Web端進(jìn)行訪問,大數(shù)據(jù)的網(wǎng)絡(luò)傳輸會導(dǎo)致平臺運行較慢等問題。本文針對平臺的實際需求,對空間信息的數(shù)據(jù)組織、發(fā)布展示的相關(guān)技術(shù)進(jìn)行了總結(jié),并在此基礎(chǔ)上,對其中幾項關(guān)鍵技術(shù)進(jìn)行了深入研究,提出“多服務(wù)器分布式瓦片裁剪技術(shù)”,將分布式概念引入瓦片裁圖技術(shù)中,實現(xiàn)了影像數(shù)據(jù)裁剪的分布式,提高了裁圖效率;運用多級緩存機制,通過在用戶端開辟緩存文件存儲及服務(wù)器端三維模型隊列的方法,提高了數(shù)據(jù)利用率,盡可能減少了網(wǎng)絡(luò)傳輸?shù)臄?shù)據(jù)量,提高了平臺顯示效率;通過使用JCR內(nèi)容倉庫的JCR-170 API實現(xiàn)了多源數(shù)據(jù)的統(tǒng)一調(diào)用,提高了數(shù)據(jù)檢索及調(diào)用效率;采用創(chuàng)建矢量模型的方式建立了影像數(shù)據(jù)和屬性數(shù)據(jù)的傳遞,達(dá)到基于影像的空間檢索目的,并通過XML記錄三維模型目標(biāo)位置坐標(biāo)信息,實現(xiàn)了三維模型的定位發(fā)布。最后通過Map GIS支持的多源歷史空間數(shù)據(jù)展示平臺的實現(xiàn),以北京市為例,對其部分歷史空間數(shù)據(jù)進(jìn)行了發(fā)布展示,證實了其可行性。
[Abstract]:The multi-source historical spatial data display platform based on Internet is not perfect at present. How to realize a platform that can browse and access through Web terminal and display multi-source historical spatial information is the main goal. In this paper, some key technologies are studied and verified by examples. Through the superposition of the image data of different historical periods to display the historical changes of the city and introduce the release of 3D model, the detailed information of historical buildings can be displayed intuitively and lifelike. On this basis, the practical functions of user-defined retrieval, path analysis and so on are realized. Because of the multi-source characteristic of data, there are many difficulties in implementation. Displaying historical changes requires a large number of high-resolution image data, and the series requirements for tile clipping are very high, which results in slow cutting speed. The multi-source data include image data, vector data and model data, and the multi-source data include image data, vector data and model data. The storage and transfer of many kinds of data is also more complicated, the image data only has the position information, does not have the attribute information, cannot produce the association with the interest point of interest, therefore cannot carry on the interest point retrieval directly; The 3D model created by external software does not have spatial attribute information and can not be accurately located and published. In addition, all the data are accessed through the Web terminal, and the network transmission of big data will cause the platform to run slowly. According to the actual demand of the platform, this paper summarizes the data organization of spatial information and the related technology of publishing and displaying. On this basis, it makes a deep research on several key technologies. This paper puts forward the "multi-server distributed tile clipping technology", which introduces the distributed concept into the tile clipping technology, realizes the distributed image data clipping, improves the efficiency of clipping, and applies the multi-level cache mechanism. By opening cache file storage and server-side 3D model queue in the client side, the data utilization rate is improved, the amount of data transmitted in the network is reduced as much as possible, and the display efficiency of the platform is improved. The unified transfer of multi-source data is realized by using JCR-170 API of JCR content warehouse, and the efficiency of data retrieval and transfer is improved, and the transfer of image data and attribute data is established by creating vector model. The goal of spatial retrieval based on image is achieved, and the location and publication of 3D model is realized by recording the position coordinate information of 3D model by XML. Finally, through the realization of multi-source historical spatial data display platform supported by Map GIS, taking Beijing as an example, some of its historical spatial data are published and displayed, which proves its feasibility.
