A track monitoring system (and a method thereof) for mounting to a vehicle on a track comprising at least one rail is provided. The track monitoring system comprises a position and attitude measurement unit configured to determine a geographical position and attitude of the system during at least one pass of the vehicle on the track, a storage medium for storing track geometry data, a laser imaging and/or scanning unit configured to determine a position of the at least one rail relative to the track monitoring system, and a position of the at least one rail and surroundings relative to the track monitoring system during the at least one pass, a processor configured to determine, in the at least one pass, a first geographically referenced rail position based on the geographical position and attitude of the rail monitoring system and the position of the at least one rail relative to the system, determine, in the at least one pass, a second geographically referenced rail position based on the geographical position and attitude of the rail monitoring system and the position of the at least one rail and surroundings relative to the rail monitoring system, determine a third geographically referenced rail position based on the first and the second geographically referenced rail positions, and corresponding geographically referenced track geometry data, acquire, in a further pass, track geometry data associated with each position of the rail relative to the rail monitoring system, and the output of the position and attitude measurement unit, update, based on the third geographically referenced position of the rail, the track geometry data acquired in the further pass, and store updated track geometry data to the storage medium.

Track monitoring system

A method and a system () for inspecting and/or mapping a railway track (). The method comprises: acquiring geo-referenced rail geometry data associated with geometries of two rails () of the track along the section; acquiring geo-referenced 3D point cloud data, which includes point data corresponding to the two rails and surroundings of the track along the section; deriving track profiles of the track from the geo-referenced 3D point cloud data and the geo-referenced rail geometry data; and comparing the track profiles and generating enhanced geo-referenced rail geometry data and/or enhanced geo-referenced 3D point cloud data based on the comparison.
