A METHOD FOR CLASSIFYING A MULTITUDE OF IMAGES RECORDED BY A CAMERA OBSERVING A PROCESSING AREA AND LASER MATERIAL PROCESSING HEAD USING THE SAME |
摘要 |
The present invention relates to a method for classifying a multitude of images recorded by a camera observing a processing area of a workpiece processed by a processing beam, comprising the steps of: recording a first pixel image and a multitude of subsequent pixel images by the camera during a processing operation; detecting mismatches of a position and orientation of a keyhole generated by the processing beam in the workpiece within an image plane of the subsequent pixel images in comparison to the first pixel image; compensating the mismatches of the position and orientation of the respective keyholes in the subsequent pixel images with regard to the first pixel image, to produce a set of pixel images having each a normalized keyhole position and orientation; classifying the set of normalized pixel images into at least two classes by means of a classifier. |
