Computer vision technology for seam tracking in robotic GTAW and GMAW
Using computer vision technology, we have solved some problems of seam tracking in robotic welding automation. We have designed a set of special vision sensor system for seam tracking and it has worked very well. A new improved Canny edge detection algorithm was proposed to detect the edges of weld image. We have further improved the precision of image processing in seam tracking. This paper systematically studied the application of computer vision technology in robotic GTAW and GMAW.
