| Abstract: | This thesis deals with the problem of seam detection for robotic laser welding applications. Within the Mechanical Automation laboratory of the Engineering Technology faculty, a compact, lightweight and multi-purpose welding head is developed. The integrated welding head is attached to a robot and should be able to detect seams, learn trajectories, do the laser welding and inspect the welds. A video camera is attached to the laser focussing optics to obtain a realtime stream of images of the work piece when the robot moves the head along the seam. This report focusses on compensating the camera images for radial distortions introduced by the welding optics, detection of the seam in the camera images and the translation of image coordinates (in pixels) to real world coordinates (in millimetres). |
