Abstract：Virtual reality (VR) and Augmentation reality (AR) have been applied to aircraft assembly with the development
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 assembly.
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.
