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 rolling stock is an 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 error is inadmissible for modern and perspective surface railway transport and metro. For analysis and calibration of the creative photonic velocity sensor (PhVS) it is necessary to select the test images applicable images, the sensor in the substantial working conditions is perceived. PhVS is constructed on the basis of specialized photosensing charge-coupled device for determination of moving velocity for railway transport.
