%X This paper presents a vision system designed for measuring horizontal and vertical displacements of a railway wagon body. The model comprises a commercial webcam and a cooperative target of an appropriate shape. The lateral buffer movement is determined by calculating target displacement in real time by processing the camera image in a LabVIEW platform using free OpenCV library. Laboratory experiments demonstrate an accuracy which is better than ¡À0.5 mm within a 50 mm measuring range.
