【摘要】：隨著旅游成為大眾化的必需品和日益平民化，旅游業(yè)成為了第三產(chǎn)業(yè)一個十分重要的支柱。旅游業(yè)對地區(qū)發(fā)展的帶動性，對城市就業(yè)的拉動能力，對城市文化和名片的宣傳效應(yīng)也日漸凸顯。作為信息密集型行業(yè)，基于虛擬現(xiàn)實技術(shù)的虛擬旅游不僅可以提升整個行業(yè)的信息化程度和行業(yè)的服務(wù)能力及資源的優(yōu)化配置，還可以促進對自然、人文旅游資源的保護。 由于Flash播放器在目前互聯(lián)網(wǎng)用戶中的使用率高達90%以上，因此，一個基于Flash3D的在線虛擬旅游系統(tǒng)，不僅不需要安裝插件，而且可以整合目前最常用的多媒體元素，通過互動漫游設(shè)計，給游客提供更逼真的感受，實現(xiàn)用戶體驗質(zhì)的飛躍。 本文提出并實現(xiàn)了一個高效的、擴展性強的、可移植性高的在線虛擬旅游系統(tǒng)。系統(tǒng)基于消息機制，通過XML文件來實現(xiàn)各個模塊和參數(shù)的集成和按需配置。通過對制約在線虛擬旅游系統(tǒng)的瓶頸分析，提出并設(shè)計了一個對三維場景構(gòu)建過程的各個步驟都進行優(yōu)化設(shè)計的方案，包括對模型文件、材質(zhì)文件以及構(gòu)建步驟的優(yōu)化設(shè)計。針對目前虛擬旅游系統(tǒng)中表現(xiàn)方式單一的問題，本文實現(xiàn)了對各種多種媒體方式的支持，包括三維對象、Flash、視頻、音頻和圖片等。通過本文的熱點系統(tǒng)，不僅實現(xiàn)三維系統(tǒng)中對Flash的支持，通過熱點的響應(yīng)，還能對三維模型按需進行加載和展示，提高游客與景區(qū)的互動。 通過對目前虛擬旅游系統(tǒng)漫游方式的研究，系統(tǒng)提出了一種新的互動漫游控制方法。利用WayPoint方法和最短路徑尋路算法，實現(xiàn)了游客在場景中任意兩點之間沿最短路徑漫游，并通過一系列的漫游過程的優(yōu)化設(shè)計，使漫游達到接近真實的漫游效果。系統(tǒng)基于用戶體驗的理論，結(jié)合系統(tǒng)的需求，實現(xiàn)了虛擬旅游系統(tǒng)中地圖，，菜單等通用功能基于Flash的設(shè)計和實現(xiàn)。 本文在綜合考慮我國旅游業(yè)信息化基礎(chǔ)上，對目前虛擬旅游系統(tǒng)的瓶頸進行分析，提出并實現(xiàn)了一個基于Flash3D的性能經(jīng)過顯著優(yōu)化的在線虛擬旅游系統(tǒng)，為我國虛擬旅游的大規(guī)模應(yīng)用的提供了借鑒。
[Abstract]:Tourism has become a very important pillar of the tertiary industry. Tourism plays an important role in regional development, urban employment, city culture and business card. As an information-intensive industry, virtual tourism based on virtual reality technology can not only enhance the information level of the whole industry, the industry's service capacity and the optimal allocation of resources, but also promote the protection of natural and humanistic tourism resources. Since the Flash player is currently used by more than 90% of Internet users, an online virtual travel system based on Flash3D not only does not need to install plug-ins, but also integrates the most commonly used multimedia elements. Through interactive roaming design, to provide visitors with more realistic feelings, to achieve a qualitative leap in user experience. This paper proposes and implements an online virtual tourism system with high efficiency, expansibility and portability. Based on message mechanism, the system realizes the integration and on-demand configuration of various modules and parameters through XML files. Through the bottleneck analysis of the online virtual tourism system, a scheme is proposed and designed to optimize the design of each step of the 3D scene construction process, including the optimization design of the model file, material file and construction steps. Aiming at the problem of single representation in virtual tourism system, this paper realizes the support of various media methods, including 3D object flash, video, audio and picture, etc. Through the hot spot system in this paper, not only the support for Flash in the 3D system is realized, but also the 3D model can be loaded and displayed on demand through the response of the hot spot, and the interaction between tourists and scenic spots can be improved. A new interactive roaming control method is proposed by studying the roaming mode of virtual tourism system. The WayPoint method and the shortest path finding algorithm are used to realize the tourists roaming along the shortest path between any two points in the scene. Through the optimization design of a series of roaming processes, the roaming can reach the real roaming effect. Based on the theory of user experience and the requirements of the system, the general functions of map and menu in the virtual tourism system are designed and implemented based on Flash. Based on the analysis of the bottleneck of the present virtual tourism system, this paper proposes and implements an online virtual tourism system based on Flash3D, the performance of which has been significantly optimized. It provides a reference for the large-scale application of virtual tourism in China.
