Augmented reality in peg-in-hole microassembly operations

An Augmented Reality (AR) technology is implemented for vision-based microassembly operations. A CAD model for the virtual microassembly system is generated and the virtual system is calibrated with real one to simulate the same image features in a virtual environment. By employing the static AR, the hidden feature of mating hole in a rod is reconstructed in image. In the real-time operation, a dynamic AR is implemented to handle the issue of different velocities of moving object in virtual environment and real system. By utilizing the image information from AR, the performance in manual and automatic assembly is experimentally tested. The effectiveness and efficiency of employing AR in peg-in-hole microassembly is concluded.
