Abstract
In work is considered the problem arising at measurement of wheel pairs parameters during the movement of a train, owing to the complex form and a brilliant surface of a rim of a wheel. The submitted device allows to expand essentially a dynamic range of a photo camera with CCD image sensor. Comparative characteristics of gauges with a feedback on intensity are given. The design of the guage and a function chart of measuring system are described on the basis of these gauges. Application of a contactless optical method of a laser triangulation is most perspective for measurement of the geometrical sizes of wheel pairs on the moving train. Its application will allow to reduce time of the control and to raise safety of transportations.
