A study on vision sensors for seam tracking of height-varying weldment. Part 1 Mathematical model

Among the various types of sensors used in welding automation, arc and vision sensors are widely used for automatic seam tracking and quality control of arcwelding processes. The development of a vision sensor which can provide 3D geometry information is needed especially for robot guidance in automatic welding of thinplates, because it is difficult to apply an arc sensor to the welding of ..
