【摘要】：增強現(xiàn)實(Augmented Reality,AR)技術(shù),是一種利用計算機技術(shù)計算產(chǎn)生的額外信息增強和擴張真實世界景象的新型技術(shù)。該技術(shù)在制造、裝飾與維修、醫(yī)療、軍事訓(xùn)練、遠程機器人和娛樂等領(lǐng)域都有明顯的優(yōu)勢。鑒于增強現(xiàn)實技術(shù)有著巨大的發(fā)展和應(yīng)用潛力,國外越來越多的專家和研究機構(gòu)都將目光轉(zhuǎn)向這一新技術(shù)。國內(nèi)對于虛擬現(xiàn)實的研究起步比較晚,在增強現(xiàn)實方面的研究比較薄弱。因此本文對增強現(xiàn)實技術(shù)進行了研究。目前移動平臺最為主流的兩個系統(tǒng)分別為Android和IOS,而在中國,Android占有更大的市場份額,因此本文的研究以Android為主,深入研究移動增強現(xiàn)實的相關(guān)技術(shù),結(jié)合Unity3D開發(fā)平臺,最終實現(xiàn)了一款可以在真實設(shè)備上正常運行的增強現(xiàn)實應(yīng)用軟件。本文首先介紹了課題的研究背景和意義,之后闡述了國內(nèi)外對AR技術(shù)的研究現(xiàn)狀和發(fā)展前景并引出了本論文的論述結(jié)構(gòu)以及研究內(nèi)容;其次,介紹了在AR領(lǐng)域的幾項關(guān)鍵性技術(shù),即圖像渲染融合技術(shù)、三維注冊模擬技術(shù)、3D模型以及虛實融合技術(shù)等;最后,本系統(tǒng)采用目前較流行的高通QCAR開發(fā)包Unity Extension開發(fā)技術(shù),設(shè)計并實現(xiàn)了基于Android的增強現(xiàn)實系統(tǒng)。該系統(tǒng)可以通過對目標圖片的識別,將虛擬的3D模型添加到真實場景中,并且可以根據(jù)目標圖片的位置角度實時控制3D模型的位置、角度,達到3D模型與真實場景較好的融合效果,并對系統(tǒng)的測試結(jié)果進行了分析。實驗結(jié)果表明,本系統(tǒng)實現(xiàn)了真實世界與虛擬世界的融合以及用戶與融合后的世界進行交互,使用戶具有一定的沉浸感,對增強現(xiàn)實技術(shù)在移動智能終端上的應(yīng)用研究進行了有效探索。
[Abstract]:Augmented reality AR (AR) technology is a new technology to enhance and expand the real world scene with the extra information generated by computer computing. The technology has obvious advantages in manufacturing, decoration and maintenance, medical care, military training, remote robotics and entertainment. In view of the great development and application potential of augmented reality technology, more and more foreign experts and research institutions have turned their attention to this new technology. The research on virtual reality starts late in China, and the research on augmented reality is weak. Therefore, the augmented reality technology is studied in this paper. At present, the two most popular mobile platform systems are Android and IOS. but they occupy a larger market share in China. Therefore, the research in this paper is based on Android, and deeply studies the related technologies of mobile augmented reality, combining with the Unity3D development platform. Finally, it realizes an augmented reality application software which can run normally on real equipment. This paper first introduces the research background and significance of the subject, then describes the research status and development prospects of AR technology at home and abroad, and leads to the structure and research content of this paper. This paper introduces several key technologies in AR field, such as image rendering and fusion technology, 3D registration simulation technology and virtual reality fusion technology, etc. Finally, the system adopts the popular Unity Extension development technology of Qualcomm QCAR development kit. An augmented reality system based on Android is designed and implemented. The system can add the virtual 3D model to the real scene through the recognition of the target image, and can control the position and angle of the 3D model according to the position angle of the target image in real time. The 3D model and the real scene are fused well, and the test results of the system are analyzed. The experimental results show that the system realizes the integration of the real world and the virtual world and the interaction between the user and the merged world, which makes the user have a certain sense of immersion. This paper explores the application of augmented reality technology in mobile intelligent terminals.
