增强现实技术综述

A Survey of Augmented Reality Technology

增强现实技术是将计算机渲染生成的虚拟场景与真实世界中的场景无缝融合起来的一种技术,它通过视频显示设备将虚实融合的场景呈现给用户,使人们与计算机之间的交互更加的自然,同时具有广泛的应用前景,因此成为近年来的一个研究热点;随着跟踪注册技术的进步、计算机性能的飞速发展、深度摄像机的普及,以及Light Field投影技术在增强现实中的应用,增强现实技术逐渐成为下一代人机交互的发展方向;该文章首先概述了增强现实的主要研究内容和发展情况,并详细介绍了增强现实的关键技术、开发工具,然后分类概述了增强现实应用案例。

This paper presents a survey on the field of Augmented Reality, which combines virtual computer-generated material with the surrounding physical world, registers real and virtual object with each other and runs interactively at real time. Augmented Reality makes use of video display device to present the situation after the fusion of virtual and reality to the user, thus greatly improving the human visual experience. Augmented Reality technology is a new technology which is produced in recent years with the development of virtual reality tech- nology. Augmented Reality research encompasses a large number of areas in computer science. With the development tracking technology, the image quality and the rapid development technology have become a new requirement. The paper introduces the primary content and state of art in this field. The key technologies, including basic tracking methods, display devices and registration processes, are discussed. Many typical AR applications and developing tools are listed. Finally, the paper describes different AR application.
