Abstract: Tracking technique is one of the most important research fields in Augmented Reality(AR). It aims at solving accurate registration problems between virtual information and real environment and building a stable and effective AR system for practical use. This paper analyzes the tracking requirements for AR applications, describes the necessity of applying hybrid tracking techniques, and specifies a hybrid approach that integrates inertial (6-DOF) and vision-based tracking techniques in AR and its applications. A hand-held AR experimental system based on VisTracker and a hybrid vision-inertial self tracker are designed. Analysis and experimental results demonstrate the system’s effectiveness and its potential application in augmented museum tour system.

Key words: Augmented Reality(AR), hybrid tracking, VisTracker hybrid vision-inertial self tracker

摘要： 跟踪技术是增强现实的一个重要研究方向，它致力于解决虚拟信息与真实环境的精确配准问题，构建稳定、高效的增强现实系统。通过分析增强现实系统的跟踪需求，指出单一跟踪存在的不足，说明采用混合跟踪技术的必要性，论述了基于视觉-惯性的混合跟踪技术及其在增强现实中的应用，实现了一种基于VisTracker视觉-惯性混合跟踪器的增强现实实验系统，并给出调试结果。
