【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.更多还原
