Relative movement correction method for robot gripper or machining tool comparing reference images and/or image data with actual images or image data

摘要

The movement correction method uses an imaging system with at least 3 cameras (10,11,12) for monitoring the relative movement between the robot gripper or machining tool and the workpiece. The workpiece is placed in a standard position and the imaging system is moved from an initial position into a series of defined positions, with storage of the obtained camera images and/or the image data in each position, for comparison with actual images for detection and correction of movement errors. An Independent claim for a device for 3-dimensional relative movement correction for a robot gripper or machining tool is also included.
