AbstractAn vision inspection sensor system for the automation of laser welding processes in heavy industries is presented. The system consists of PC based vision camera and stripe type laser diode. For image de-noising, a new surface inspection method of Tailor-welded blanks including in: median filtering, hi-level thresholding, opening and closing, mid-fine of the laser stripe extraction, has been developed. After extracting the middle line of the laser stripe, the algorithms of calculating bead width, mismatch, weld slope, convexity, concavity, overthickness and undercut are proposed. Finally, A series of experiments show that the proposed method in this paper is effective.
