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.
