Abstract

An encoded calibrating plate is fixed on the working environment of the robot arm and has a chessboard pattern with each square in the chessboard pattern being an encoding. The encoding indicates direction or position on the encoded calibration plate. A visual system of the robot arm captures an image of the encoded calibrating plate, calculates the coordinates encoding of the encoded calibration plate, and positions the visual system to calibrate a positioning error of the robot arm and the visual system.
