Abstract
A method and system of detecting obstacles on railroad lines. Sensors for observing the railroad line are arranged along the railroad line, and automatic evaluation takes place. One advantage of the invention is that the railroad lines are divided into given, known line sections, each of which is monitored by a respective sensor, whereby the evaluation process is simplified. If the sensors are designed as video cameras, for example, a comparison with still images may suffice for the evaluation. Furthermore, as the line sections re known, a simple masking technique can be used. Obstacles outside a set route to be monitored are masked out using suitable masks.
