Key Technique of Assembly System in an Augmented Reality Environment

Assembly technology aims to develop fast, reliable and low cost method to improve product design in the manufacturing industry. Augmented Reality (AR) is a promising technology which can enhance the sense of reality by combining virtual objects with real ones. When AR technique is applied in assembly to develop an AR-based assembly system, it can provide more intuitive and natural interactions and make assembly task more reliable and effective than traditional assembly techniques. This paper describes several key aspects in AR-based assembly system: occlusion handling, collision detection and human-computer interaction. A prototype system is implemented to illustrate how to apply these techniques.
