Abstract: Augmented reality (AR) is a technique that allows to seamlessly composite virtual objects or information into real scene. Compared to traditional text, images and videos, AR is a more effective and intuitive way for information presentation and has wide applications. Simultaneous localization and mapping (SLAM) is a key fundamental technique for augmented reality, which provides the ability of self-localization in an unknown environment and mapping the 3D environment simultaneously. The localization and mapping enables fusion of virtual objects and real scenes in a geometrically consistent way. In this paper, we describe the basic principles of Visual SLAM, and introduce some state-of-the-art monocular SLAM methods with deep analysis and comparison. Finally, we discuss some research tendency in recent years and make conclusions.

摘 要: 增强现实是一种在现实场景中无缝地融入虚拟物体或信息的技术, 能够比传统的文字、图像和视频等方式 更高效、直观地呈现信息，有着非常广泛的应用. 同时定位与地图构建作为增强现实的关键基础技术, 可以用来在未 知环境中定位自身方位并同时构建环境三维地图, 从而保证叠加的虚拟物体与现实场景在几何上的一致性. 文中首 先简述基于视觉的同时定位与地图构建的基本原理; 然后介绍几个代表性的基于单目视觉的同时定位与地图构建方 法并做深入分析和比较; 最后讨论近年来研究热点和发展趋势, 并做总结和展望.
