A VISION SYSTEM FOR ACCURATE POSITIONING OF CUBIC CARRIER ROBOT IN AUTOMATED WAREHOUSE

A vision system of carrier robot which operates in a high-density,heavy-load warehouse is presented.Thevision system has been designed and used practically in laboratory in real time.It is especially designed forthe carrier robot to meet high precise positioning requirements.The results show that the maximum position-ing error of this system is less than two millimeters,and the time consumption is less than one sixth second.Meanwhile the system has good stability.
