摘要(Abstract)

增强现实(Augmented Reality,简称AR), 也有对应VR虚拟实境一词的翻译称为实拟虚境或扩张现实,是指透过摄影机影像的位置及角度精算并加上图像分析技术,让屏幕上的虚拟世界能够与现实世界场景进行结合与交互的技术。这种技术于1990年提出。随着随身电子产品运算能力的提升,增强现实的用途也越来越广。增强现实技术(Augmented Reality,简称 AR),是一种实时地计算摄影机影像的位置及角度并加上相应图像、视频、3D模型的技术。随着近年来计算机硬件尤其移动设备技术的进步,增强现实技术的发展和应用越来越受到人们的重视。而另一种定义是1994年保罗·米尔格拉姆(Paul Milgram)和岸野文郎(Fumio Kishino)提出的现实-虚拟连续统(Milgram's Reality-Virtuality Continuum)。[3]他们将真实环境和虚拟环境分别作为连续系统的两端,位于它们中间的被称为“混合实境”。其中靠近真实环境的是增强现实(Augmented Reality),靠近虚拟环境的则是扩增虚境。增强现实与硬件、软件、以及应用层面息息相关。在硬件方面,结合处理器、显示器、传感器以及输入设备的载具,方能适合成为AR平台。在软件方面,AR系统的主要关键是如何将扩增的对象与现实世界结合。在应用层面,最早用于军事,而后扩及日常生活。
