Document Type and Number:
WIPO Patent Application WO/1991/019240
Kind Code:
A1
Abstract:
A system for calibrating a visual sensor in a robot system. An arm (2) of a robot (1) is provided with a pattern plate (3) for calibration, and calibration pattern data (CPDr) of a pattern plate on the base coordinates of the robot are sent from a robot controller (10) to a visual sensor controller (20). The visual sensor controller (20) takes the image of the pattern plate (3) by a camera (4) and obtains the calibration pattern data (CPDc). Calibration data (CD) are obtained from these calibration pattern data (CPDr) and (CPDs) to calibrate the visual sensor.
