An on-line vision inspection sensor system for the automation of laser welding processes in heavy industries is presented. A method of image process and features extraction for structured light image of laser welding has been developed. In order to set the range of interest, the Radon transform is applied to determine the x and y coordinate in image coordinate system. For image de-noising, the median filtering and bi-level thresholding are used. Furthermore, the middle line of the laser stripe… CONTINUE READING
