1. A device for measuring ovalization, buckling, planes and rolling parameters of railway wheels using artificial viewing, characterised in that it comprises on each side of the railway track a measuring area (L);

  • a rolling rail (2) along which the wheel (1) to be measured is made to pass at a speed of about 10 km/h;

    a counterrail (3) to centre said wheel (1) during the measuring process;

    a collimated laser beam coming from a laser system (6), illuminating the flange and the rolling profile whilst the wheel (1) crosses the measuring area;

    a screen (4) on which the contour shadow is projected;

    a video camera (5) to capture and transmit the images projected on the screen;

    an artificial viewing system (9) connected to the video camera which digitalises and processes the received images, obtaining the parameters to be measured relative to ovalization, buckling, planes and rolling parameters;

    a computer (10) connected to the artificial viewing system, showing the obtained values and storing the captured images;

    optical wheel position sensors (7) detecting the wheel presence and enabling and disabling image capture; and

    a control system (8) governing the sensors (7).
