Abstract
A method for automatically effecting calibration between an image processing apparatus and a control device of an automatic machine. Jig data for calibration and the position of a robot, fitted with a jig which can be photographed by a camera at the time of calibration, are previously given as instructions. In response to a calibration command, the robot, fitted with the jig, moves to a point of instruction, the image processing apparatus photographs the jig and fetches an image after the movement. A calibration process is executed in accordance with data of the photographed image, set jig data, and robot position. When the jig data and the instruction point are first set and given once as instructions, the calibration thereafter can be automatically effected only by mounting the jig on the robot and inputting the calibration command.
