Abstract In the manual link of aircraft assembly, the combination of virtuality and reality by the AR technology can be used to display the instructions in the scene of assembly. High quality combination of virtuality and reality requires the ability of accurate localization of the AR system. This paper proposes a method of localization by using simultaneous localization and mapping (SLAM) based on the constraint of planar markers for AR-based assembly. Firstly, the AR system generates the original AR map using the SLAM method. Then, it detects the planar markers in the key frames of the AR map, and the constraint of the markers is employed on the transformation and the optimization of the key frames and the map points to build the high-quality AR map. Finally, the AR system tracks the new AR map for registration and view point tracking to enable high accuracy localization under the coordinate system of the assembly scene. The verification experiments demonstrate that the method can effectively improve the accuracy of localization of the AR system.
