【摘要】 随着人们对于各种复杂场景导航需求的增加，室内实景导航逐渐成为研究人员关注的一个重要领域，尤其是在GPS(Global Positioning System)信号不强或受到影响的商业区、地下室以及各大展馆等，实景导航可以利用室内环境特征，不借助GPS信号实现精准导航。通过介绍实景导航发展现状，AR技术的概念特点，并从基于AR的导航工作原理、关键技术以及发展趋势来分析AR技术如何应用于室内实景导航，为室内实景导航技术的发展提供借鉴。更多还原

【Abstract】 With the increase in people’s demand for navigation of various complex scenes, indoor real-scene navigation has gradually become an important area of concern for researchers, especially in commercial areas, basements and major exhibition halls where GPS(Global Positioning System) signals are not strong or affected, and real-scene navigation can use indoor environmental characteristics to achieve accurate navigation without the help of GPS signals. By introducing the development status of real-scene navigation, the conceptual characteristics of AR technology, and analyzing how AR technology is applied to indoor real-scene navigation from the working principle, key technologies and development trends of AR-based navigation, it provides reference for the development of indoor real-scene navigation technology.更多还原
