计算机视觉在焊缝跟踪控制中的应用

摘要

研究一种基于计算机视觉的焊缝跟踪控制系统,重点论述焊缝图象分割和边缘提取的理论方法,通过对视觉传感器CCD检测到的弧焊区图象进行处理来准确地识别焊缝位置,从而有效地提高焊缝跟踪精度.%A control system based on the computer vision for weld seamtracking 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.
