增强现实技术将虚拟信息与真实环境融合起来，并通过显示设备将其呈现在用户所在的现实世界中，同时为用户提供自然的人机交互体验。本文综述了增强现实系统中的关键技术研发进展，论述了其在工业制造、医疗、军事、游戏、教育等领域现实中的应用，并展望了增强现实技术的发展趋势。
The augmented reality technology combines virtual materials with the real world, displays the mixed information in the surrounding physical world via display devices, and provides a natural human-computer interaction. Recently, the augmented reality technology sees a rapid developement, and is widely used in thefields of games, entertainment, exhibitions, education and so on. This paper reviews the key technologies of the augmented reality system, its application in practice, as well as its future development.
