Abstract
A visual sensor calibration method of calibrating of a visual sensor in a robot system. A pattern plate is provided on an arm of a robot, and the calibration pattern data (CPDr) of the pattern plate on robot's base coordinates is sent from a robot controller to a visual sensor controller. The visual sensor controller picks up an image of the pattern plate by a camera to obtain calibration pattern data (CPDc). The calibration data (CD) is obtained from the calibration pattern data (CPDr) and the calibration pattern data (CPDc), to thereby calibrate the visual sensor.
