Method for imaging workpiece surfaces at high robot transfer speeds with correction of motion-induced distortion |
摘要 |
A method is provided for imaging a workpiece by capturing successive frames of an elongate stationary field of view transverse to a workpiece transit path of a robot, while the workpiece is transported by the robot. The robot transit path is illuminated with an elongate illumination pattern transverse to the transit path to obtain a workpiece image of successive frames. Motion-induced image distortion is corrected by computing respective correct locations of respective ones of the frames along the transit path.
