Railway traffic causes an abrasion of the rail shapes. Regularly, it is necessary to add some bead layers in order to re-enter the dimension tolerances. At present, the welding operation is manually performed. The aim of the project is the automation of this welding operation. The system, mounted on carriage rolling on the rails, is to detect the worn out rail parts, to acquire the geometry of the abrasion and to control the welding reparation. At first, the paper presents the 3D visual sensor (range finder) used for the geometrical measurements. The involved principle is a triangulation technique. Next, the data treat ments are outlined as for the accurate localisation of the worn out part and the geometric measurement of the abrasion. Finally practical results are given with some conclusions about the accuracy and reliability of the system.
