Abstract-To track the narrow butt welding seams in container manufacture, a visual tracking system based on smart camera is proposed in this paper. A smart camera is used as the sensor to detect the welding seam. The feat ure extraction algorithm is designed with the consideration of the characteristi cs of the smart camera, which is used to compute the error between the welding t orch and the welding seam. Visual control system based on image is presented, wh ich employs a programmable controller to control a stepper motor to eliminate th e tracking error detected by the smart camera. Experiments are conducted to demo nstrate the effectiveness of the vision system.
