Railway track image processing to calibrate the photonic velocity sensor

Velocity is an important feature of transportation, which in many respects defines safety of the movement, keeping of the trains schedule and parameters of navigation (definition of exact coordinate of a train on the railway). The accuracy measurement of velocity for the rolling stock is the important problem for railway transport, as the solution will ensure increase of safe passengers' transportation. At the present time electromechanical sensors are applied, on rail transport to determine the velocity of the movement. The work of the sensors is based on calculation of number of turns of a wheel. An error of measurement makes about 5 km/h, which is caused by slipping in and wearing out of wheels. Such value of an error is inadmissible for modern and perspective surface railway transport and metro.
