Application of Computer Vision in the Weld Seam Tracking Control
计算机视觉在焊缝跟踪控制中的应用

A control system based on the computer vision for weld seam tracking is proposed. The discussion is mainly focused on the theory and methods of edge collection and division of weld image. The weld position can be detected accurately through processing the image of arc area collected by the vision sensor CCD (charge coupled device), and the seam tracking accuracy is enhanced efficiently.
