Abstract (en)
A system and a method for detecting the class of a vehicle in transit along a road section are described. An image acquisition device acquires the images of the vehicle, in which the license plate (or license plates) of the vehicle is/are visible. In the acquired images the license plate is identified, its properties (shape, syntax of the license plate number, number of visible license plates of the vehicle) are determined and, if these properties uniquely indicate that the vehicle belongs to a certain class, it is concluded that the vehicle belongs to that class. If this is not the case, it is determined whether in the images acquired there are present further retroreflective elements which, according to the existing regulations, must be affixed to certain categories of vehicles (retroreflective panels for trucks or for semi-trailer trucks, etc.). Then the properties of these possible further elements are determined and, if these uniquely indicate that the vehicle belongs to a certain class, it is concluded that the vehicle belongs to that class.
