Abstract: Aiming at the significance of applied Machine VIsion (MVI) on promoting manufacturing development,by taking Assembly Operation of Mechanical Products (AOMP) as the research object,MVI-based assembly operation framework of mechanical products was put forward based on analyzing the application characteristics of MVI in manufacturing industry.Under this framework,MVI factors and its image processing algorithms of AOMP were defined respectively.On this basis,a Knowledge-Based Object-Oriented Petri Net (K-OPN) model on integrating MVI in the AOMP was presented.The knowledge rules were adopted to deal with the invalid algorithm case and system deadlock of K-OPN model.Based on HALCON machine vision,a MVI-based prototype system for gearbox was developed to verify the feasibility and effectiveness of this method.
