增强现实及其在导航与位置服务中的应用

摘要

Augmented reality (AR) is a technology to enhance human perception and cognition of real world. The elements in a physical environment are augmented by kinds of sensory information or computer-generated predications. The information about the environment and its objects can be overlaid on the real world via internet. This paper surveyed the field of augmented reality from conceptual aspect, development history, key technology and application domains. A detailed discussion on how to supplement the interactive level with augmented reality was given for personalized location based service, and ubiquitous mapping as well. Future directions and major issues of augmented reality requiring further research were summarized in the end.%对增强现实从概念内涵、发展历程、关键技术及应用领域等方面进行了论述;对如何使其为导航与位置服务带来个性化的深度服务,并延伸至泛在测绘等领域进行了探讨;最后就增强现实的发展趋势和待解决的问题阐述了观点.
