Abstract: Aiming at the problem of large randomness and difficulty in grasping the displays on the display assembly line,a display grabbing system of random pose based on the vision was proposed. The system used the visual toolkit of Labview to collect and calculate the images,and generated the position data of different types of displays,and sended the data to the PLC to control the grasping action of the robot. The experimental platform was built with cartesian robot,industrial camera and industrial computer as the hardware foundation,and the human-computer interaction interface was configured with Labview software. The experimental shows that the coordinate error of the system is less than 0. 4 mm,and the maximum angle error is within 0. 3°. It is suitable for different types of displays,and the grasping system has good accuracy and high reliability.

Key words: Labview, vision, cartesian robot, image processing
