Method and system for detecting a rail track

摘要

A method of detecting a rail track (1) in front of a track-bound vehicle (2), the method comprising the steps of: providing (20) a thermal camera (3) facing substantially forward in the direction of travel of the vehicle (2), acquiring (40) at least one thermal image (5) of a scene (4) in front of the vehicle (2) by means of the thermal camera (3), providing (50) at least one scene geometry based on information concerning the thermal camera (3) and information concerning the rail track (1), the scene geometry comprising at least one possible position and extent of the rail track (1), and matching (60) the thermal image (5) with the scene geometry to determine where in the thermal image (5) the rail track (1) is positioned. In embodiments of the method obstacles (11) in a rail track area and potential obstacles (12) moving towards the detected rail track (1) may be detected. Disclosed is also a method of detecting an anomaly on or near an area which moves along a movement direction relative to a camera
