In order to be able to determine a vehicle position (FZP) of a rail-bound vehicle (FZ, SFZ) relative to a fixed position obtained by pre-locating and to do so with greater local accuracy, according to the invention the position of the vehicle is determined using a marking (MK, SZ) attached along a route (FST) of the rail-bound vehicle, and the marking position (MKP, SZP) of said marking, wherein - from a region of the route in which the marking is expected, a route image (SB) is captured from the perspective of the vehicle at a fixed vehicle position (FZFP) at a distance from from the marking position, - on the basis of the route image, at regular time intervals at a given vehicle speed, proceeding from the fixed vehicle position, it is iteratively evaluated for corresponding, differing and diminishing distances to the marking position how strongly an image section to be observed, which varies in relation to the marking position relative to the vehicle speed, deviates from a marking (MK', SZ') known according to the reference route images (RSB) with respect to the marking to be detected during the course of a combination of image calculation and image analysis for marking detection, carried out on the basis of the route image, the fixed vehicle position and the saved reference route images and additional data, - it is evaluated which image sections contain the smallest deviations and, according to said image section evaluation, the marking is detected by a consistent marking comparison and the vehicle position is thereby determined.
