【摘要】： 增強(qiáng)現(xiàn)實(shí)(Augmented Reality)是90年代初開(kāi)始興起的新技術(shù)及研究熱點(diǎn),是虛擬現(xiàn)實(shí)技術(shù)發(fā)展的一個(gè)重要分支,具有虛實(shí)結(jié)合、實(shí)時(shí)交互、三維注冊(cè)的特點(diǎn)。與虛擬現(xiàn)實(shí)系統(tǒng)不同,增強(qiáng)現(xiàn)實(shí)仍然處于實(shí)驗(yàn)室階段。盡管對(duì)室內(nèi)增強(qiáng)現(xiàn)實(shí)系統(tǒng)的研究已經(jīng)取得了比較大的進(jìn)展,但是尚沒(méi)有成熟的室外增強(qiáng)現(xiàn)實(shí)應(yīng)用系統(tǒng)�；谏鲜霰尘�,從探索增強(qiáng)現(xiàn)實(shí)戶外應(yīng)用系統(tǒng)的實(shí)現(xiàn)出發(fā),研究開(kāi)發(fā)了一個(gè)應(yīng)用于室外的增強(qiáng)現(xiàn)實(shí)系統(tǒng)——虛擬雕塑實(shí)景顯示系統(tǒng)。該系統(tǒng)的實(shí)現(xiàn),為雕塑與環(huán)境的整體設(shè)計(jì)規(guī)劃提供了直觀的形象化顯示,有助于雕塑作品的構(gòu)思、方案選擇和整體效果的預(yù)覽。 文中探討了增強(qiáng)現(xiàn)實(shí)技術(shù)在戶外設(shè)計(jì)規(guī)劃領(lǐng)域中的應(yīng)用和基于增強(qiáng)現(xiàn)實(shí)技術(shù)的虛擬雕塑實(shí)景顯示系統(tǒng)的實(shí)現(xiàn)技術(shù)。根據(jù)增強(qiáng)現(xiàn)實(shí)的基本特性和系統(tǒng)的運(yùn)行原理,分析了該系統(tǒng)的功能和系統(tǒng)的性能要求,論述了系統(tǒng)的基本結(jié)構(gòu),其中包括系統(tǒng)的軟硬件組成原理,闡述了系統(tǒng)運(yùn)行流程以及系統(tǒng)實(shí)現(xiàn)的相關(guān)算法原理,實(shí)現(xiàn)了交互界面設(shè)計(jì),完成了原型系統(tǒng)的設(shè)計(jì)與實(shí)現(xiàn),最后對(duì)系統(tǒng)進(jìn)行了相關(guān)的實(shí)驗(yàn),并得出了初步的實(shí)驗(yàn)結(jié)果。系統(tǒng)首先通過(guò)DirectShow將采集到的現(xiàn)實(shí)場(chǎng)景視頻錄像讀到系統(tǒng)中,通過(guò)對(duì)視頻圖像中的顏色塊的識(shí)別,獲取特殊標(biāo)記的相關(guān)信息,利用這些信息求解攝像機(jī)的參數(shù),配準(zhǔn)虛擬信息與真實(shí)世界場(chǎng)景,確定屏幕坐標(biāo)與世界坐標(biāo)的變換關(guān)系,最后將導(dǎo)入到系統(tǒng)中的虛擬雕塑模型疊加到真實(shí)場(chǎng)景視頻圖像中,從而實(shí)現(xiàn)虛擬圖形與現(xiàn)實(shí)場(chǎng)景的融合。在系統(tǒng)實(shí)現(xiàn)過(guò)程中,針對(duì)戶外環(huán)境,采用基于標(biāo)志點(diǎn)的注冊(cè)算法實(shí)現(xiàn)系統(tǒng)的三維注冊(cè),最后通過(guò)實(shí)驗(yàn)效果驗(yàn)證了算法的正確性。 本課題對(duì)基于增強(qiáng)現(xiàn)實(shí)技術(shù)的虛擬雕塑實(shí)景顯示系統(tǒng)的相關(guān)問(wèn)題進(jìn)行了研究,并初步實(shí)現(xiàn)了其原型系統(tǒng),為今后更深層次和更廣泛的研究工作提供初步的實(shí)驗(yàn)平臺(tái)和有力參考。
[Abstract]:Augmented reality (augmented reality) is a new technology and research hotspot that began to rise in the early 1990s. It is an important branch of the development of virtual reality technology. It has the characteristics of virtual reality combination, real-time interaction and 3D registration. It is different from virtual reality system. Augmented reality is still in the laboratory stage. Although the research on indoor augmented reality system has made great progress, there is no mature outdoor augmented reality application system. Based on the realization of the outdoor application system of augmented reality, an augmented reality system, virtual sculpture real scene display system, is developed. It provides visual display for the overall design planning of sculpture and environment, which is helpful to the conception, scheme selection and preview of the overall effect of sculpture works. This paper discusses the application of augmented reality technology in the field of outdoor design planning and the realization technology of virtual sculpture actual scene display system based on augmented reality technology. The function of the system and the performance requirements of the system are analyzed. The basic structure of the system is discussed, including the principle of the software and hardware of the system, the running flow of the system and the related arithmetic principle of the system realization, and the design of the interactive interface is realized. The design and implementation of the prototype system is completed. Finally, the system is experimented with and the preliminary experimental results are obtained. Firstly, the system reads the real scene video to the system through DirectShow. Through the recognition of the color blocks in the video image, the relevant information of the special mark is obtained, and the parameters of the camera are solved by these information, the virtual information is registered with the real world scene, and the transformation relationship between the screen coordinates and the world coordinates is determined. Finally, the virtual sculpture model imported into the system is superimposed into the real scene video image to realize the fusion of the virtual graphics and the real scene. The registration algorithm based on the mark point is used to realize the 3D registration of the system. Finally, the correctness of the algorithm is verified by the experimental results. In this paper, the related problems of virtual sculpture scene display system based on augmented reality technology are studied, and the prototype system is implemented. It provides a preliminary experimental platform and powerful reference for further and more extensive research work in the future.
