Research on calibration device of AR aided assembly system

Aiming at the problems that AR aided assembly system can not be accurately calibrated and the value can not be traced, a calibration device with visual processing system is designed. The calibration method of projection error of AR assisted assembly system was systematically analyzed by comparison and theoretical research methods. The calibration device was calibrated by finite element analysis and binocular camera calibration. The uncertainty of measurement results of projection error of calibration device was evaluated by GUM evaluation method.
