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.
