  • Patent number: 10607090
    Abstract: A method for identifying an alteration of an object in the vicinity of a train in operation travelling on a rail track along a route. The train is operative to transport passengers or cargo. The method includes capturing image data of an object located at a point of interest along said route when said train is operational on said rail track. Furthermore, said image data is analyzed to find matching reference image data stored in a data storage device. Based on said matching reference image data, said object is located at a position within said point of interest. Further, said image data is analyzed to find an alteration of said object compared to said matching reference image data. If an alteration is found, an action depending may be taken.
