【摘要】：增强现实(Augmented Reality,AR)技术,是一种利用计算机技术计算产生的额外信息增强和扩张真实世界景象的新型技术。该技术在制造、装饰与维修、医疗、军事训练、远程机器人和娱乐等领域都有明显的优势。鉴于增强现实技术有着巨大的发展和应用潜力,国外越来越多的专家和研究机构都将目光转向这一新技术。国内对于虚拟现实的研究起步比较晚,在增强现实方面的研究比较薄弱。因此本文对增强现实技术进行了研究。目前移动平台最为主流的两个系统分别为Android和IOS,而在中国,Android占有更大的市场份额,因此本文的研究以Android为主,深入研究移动增强现实的相关技术,结合Unity3D开发平台,最终实现了一款可以在真实设备上正常运行的增强现实应用软件。本文首先介绍了课题的研究背景和意义,之后阐述了国内外对AR技术的研究现状和发展前景并引出了本论文的论述结构以及研究内容;其次,介绍了在AR领域的几项关键性技术,即图像渲染融合技术、三维注册模拟技术、3D模型以及虚实融合技术等;最后,本系统采用目前较流行的高通QCAR开发包Unity Extension开发技术,设计并实现了基于Android的增强现实系统。该系统可以通过对目标图片的识别,将虚拟的3D模型添加到真实场景中,并且可以根据目标图片的位置角度实时控制3D模型的位置、角度,达到3D模型与真实场景较好的融合效果,并对系统的测试结果进行了分析。实验结果表明,本系统实现了真实世界与虚拟世界的融合以及用户与融合后的世界进行交互,使用户具有一定的沉浸感,对增强现实技术在移动智能终端上的应用研究进行了有效探索。
[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.
