The use of structured lighting in computer vision systems

I suggest using a structured lighting for detecting the presence of a train on a controlled track and fixing car-to-car gaps in vision systems on the railway. This approach eliminates the need of special sensors or additional equipment for the specified control and, in conjunction with other decisions of complex technology articulating design of all components of vision systems, allows to increase the maximum speed of trains passing through the checkpoints, to improve significantly the accuracy of the process of recognition of identification numbers of cars and containers, makes it possible to bring the camera closer to the track, to control all roads of the railway station simultaneously under the minimal distance between them.
