Abstract：In this paper, augmented reality (AR) is combined with 3D digital technology and artificial intelligence (AI) to realize the operation guidance, information perception and error prevention of assembly site. Firstly, based on the characteristics of manual assembly, the composition architecture and application mode of the AR intelligent assembly assistance system are proposed, and then 3D digital assembly process modeling, on-site AR registration/tracking/ fusion display, and AR real-time images are used to extract assembly feature information through AI image processing algorithms. The AR auxiliary assembly prototype system was developed based on the system composition framework and key technologies, and the application verification was carried out with the aeroengine assembly as the object. The results show that AR aided assembly can solve the problems of operation prompt, target recognition, operation guidance and error prevention in manual assembly of complex products.
