Abstract (en)

[origin: WO0221445A2] The invention relates to a method and system for determining a change in a reference object, which is associated with a travel way and which is provided at a predetermined location in the travel way. The invention provides that, at a first point in time, at least one reference image is taken at the predetermined location of the travel way. An image of the reference object is established in the at least one reference image. At a second point in time, at least one test image is taken at the predetermined location of the travel way. Another image of the reference object is established in the at least one test image. The change in the reference object is established by comparing the image of the reference object in the at least one reference image with the other image of the reference object in the at least one test image.
