A detection method for welding lines based on K-L algorithm is discussed. Infrared light source is applied to get high quality images of welding lines through CCD. Image template libraries for unwelded and welded lines are constructed and the welding line image is processed by K-L algorithm to match with the template libraries to judge if the welding line has been welded. The experiment shows that above method is effective with high precision and speed and it can be applied on real-time detection of welding lines.
