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。
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.
