Effect of some image processing on the seam tracking by a welding robot with visual sensor
- Keio Univ., Yokohama (Japan). Faculty of Science and Technology
In automatic welding of thick plates, welding robots with arc sensing system are often used. But it is difficult to apply the arc sensing system to welding of relatively thin steel plates. Therefore, an intelligent welding robot with a visual sensing system has been remarked. However, it is not always easy to recognize the weld line clearly, because the weld line is sometimes very fine and the machined surfaces of steel plates have irregular brightness distribution. Therefore, a basic Cartesian-coordinate welding robot system with a visual sensor was constructed in order to investigate the recognition and automatic tracking of the weld line of plates and image processing of brightness distributions on the recognition of weld line were discussed, and furthermore the effectiveness of the processes was experimentally confirmed.
