随着计算机技术的发展,虚拟现实技术(Virtual Reality,VR)和增强现实技术(Augment Reality,AR)已经开始应用于飞机装配.使用VR技术,能够建立一个全三维的虚拟环境,使用AR技术可以将虚拟信息叠加到现实场景中,综合运用了AR和VR的混合现实技术(Mixed Reality,MR)所建立的虚拟环境可以提供更集中、更全面的装配信息,同时建模量也大大减少.基于MR技术的虚拟装配系统可以对装配所需的大量信息进行统一、集中的管理,可以大大缩短飞机装配前置时间,减少资源浪费并能够降低成本.将虚拟环境和真实环境相匹配并融合,对工作人员而言,拓展了信息获取的渠道和范围,加强了对重要信息的感知能力,同时也降低了对工作人员视觉空间能力的要求;对装配工作而言,可以大大减少装配误差的产生、缩短装配时间、提高装配效率和装配质量.%Virtual reality (VR) and Augmentation reality (AR) have been applied to aircraft assembly with the de-velopment of computer technology. A full three-dimensional virtual environment can be built with the use of AR. Virtual information can be superimposed on the reality environment with the use of AR. Mixed reality (MR) which combines the advantages of both, allows more realistic human-computer interactions, and provides more focused and comprehensive assembly information while the modeling work can be greatly reduced. MR-based virtual assembly system can manage a great amount of information and data centrally, which means lead time and the waste of resources will be greatly reduced. The channels and scope of access to information can be expended, the important assembly information can be augmented, the requirement of workers' visual space ability can be reduced when applying the mixed environment to complete the as-sembly. Based on the above, the virtual assembly system can help to reduce the assembly error, shorten the assembly time, and improve assembly efficiency and assembly quality.
