摘要
混合跟踪是增强现实(Augmented reality,AR)领域最近二十年发展迅速的重要关键技术,是增强现实姿态跟踪系统同时实现高精度和强鲁棒性的有效途径.本文全面完整地论述了增强现实混合跟踪技术,详细阐述了混合跟踪器所涉及的混合跟踪、标定和时间同步等重要方法,介绍了不同类型混合跟踪器的当前应用现状,然后探讨了混合跟踪技术的发展趋势及其存在的难题,最后展望了混合跟踪技术的应用前景.
Hybrid tracking is one of the most important key technologies having received rapid development over the past twenty years in the field of augmented reality (AR). It is an effective approach to realize head-pose tracking with high accuracy and strong robustness for AR application systems. This paper tries to provide a complete and comprehensive survey on hybrid tracking technology. Three important issues involved in hybrid trackers are described in detail, including hybrid tracking method, calibration, and time synchronization. The state-of-the-art applications of different hybrid trackers are introduced. The pending problems and development tendency of hybrid tracking technology are discussed, and finally the application prosl^ect is reviewed.
