Computer Vision Sensing Technology and Its Application in Walding

With the development of visual sensing, image processing and artificial intelligence, the computer vision has been widely used lit the field of welding, owing to its abundant information, high precision, generic application, and wide sensing range. In this paper, the state-of-the art of the computer vision sensing technology used in welding field has been in-troduced in brief, and the typical applications of this technology have been reviewed in detail. Based on the above, the exsiting problems, which im-pede its wider spread in welding, have been point out, the development tendency of computer vision sensing technology in welding has been pros-pected.
