| Abstract: | In this paper, a visual measurement system is developed to accurately track complex seam of butt weld in the process of laser welding. Constructed by vision sensors, the system is capable to measure and calculate the seam centre line, width and normal vector. It also provides a method to transform measurement coordinate system to the camera coordinate system and optimize welding path. In this study, an experiment of tracking complex weld seam has been performed in butt laser welding. The experimental result indicates that the developed visual measurement system is able to meet the requirements of tracking control of 3-D laser welding. |
