METHOD FOR CALIBRATION OF A ROBOT INSPECTION SYSTEM

摘要

The present invention relates generally to use of an industrial robot (Robot) and a measurement device (22) attached to the robot's flange (24) in order to complete measurements in a manner similar to a Coordinate Measuring Machine (CMM). In particular, the present invention relates to use of calibration techniques to maximize position accuracy and repeatability over time of an industrial robot as well as accurately locate the coordinate frame of the measurement device (22) (e.g. a camera (36), laser (34), or other device which produces output that can be expressed in 3D coordinates) that corresponds with the Tool Center Point (TCP) of the Robot-CMM System.
