A method for vehicle identification to determine at least one vehicle characteristic, comprising: obtaining an input image (301) of the vehicle from an image source (101); normalisation of the input image (301) of the vehicle in a normalisation unit (103, 104) to obtain a normalized image; determining the vehicle characteristic in a classification unit (111, 112) by comparing parameters of a normalised image obtained in a parametrisation unit (107, 108) with parameters of reference images obtained from a reference database (113, 114). Normalisation in the normalisation unit (103, 104) comprises the steps of: detecting a registration plate area (303) within the input image (301); processing the input image (301) basing on normalisation attributes defining at least one scaling coefficient (znorm, anorm, vnorm); choosing from the scaled image (307) a RoI area (308) of a normalised size and location dependent on the location of the registration plate area (303); and presenting data from the RoI area (308) as a normalised image (311). |
