| Abstract: |
| Augmented reality is a technology that integrates virtual information with the real environment. Augmented assembly refers to the application of augmented reality technology to the assembly field, aiming to improve assembly efficiency and quality and reduce assembly training costs. This paper introduces the augmented reality assisted assembly technology. Three key technologies involved in augmented reality are described in detail, including tracking and registration technology, real-time interaction technology, virtual and real integration technology. And the implementation methods of technologies in the augmented assembly system are introduced. Then the examples of augmented reality assisted assembly are introduced, and finally the current problems in practical application are discussed. The premise of making full use of augmented reality technology is to have a perfect assembly information model. Currently, due to hardware limitations, head-mounted displays can only take a balance between portability and graphics performance. The final object of augmented assembly guidance system is workers, so it is very important to build a user-friendly augmented assembly system. |
