In the automation of arc welding with visual sensors, it is necessary to precisely detect the weld line regardless of the fluctuation in the illumination and in the reflection state of the workpiece. However, it is not easy to minimize such fluctuations at the actual construction site, especially for large-scale structures. The Hough transform is very useful for detecting straight lines, but it requires huge computational power. The proposed method uses one marked feature in weld processing. That is, the current torch position is known during the weld process. Then, the Hough transform is modified to be able to detect a straight line passing through one point, and is applied to detect straight weld lines in some practical images. Regardless of low-contrast weld lines and other features including some markings and drilled holes, the results are satisfactory and successful in detecting only weld lines, their end points and weld tacks.
