Method and system for determining the digital fingerprint of vehicles in transit

A system (1) for determining the digital fingerprint of vehicles in transit for automatic charge of tolls, fees and/or other possible treatments, comprising at least one portal (2) positioned along a road (3) and provided with at least one pair of cameras (5a, 5b) respectively facing upstream and downstream of the portal (2) in the direction of travel of vehicles on at least one lane (4) of the road (3) to shoot frontally the vehicles approaching the portal (2) and, respectively, from behind the vehicles which, having passed the portal (2), move away from it;

• and with at least one antenna (6), in particular a DSRC antenna for dedicated short-range communication, configured to interrogate vehicle on-board devices to receive an identification code therefrom;
• the system (1) further comprising a data processing system (8), connected to the cameras (5a, 5b) and the antenna (6) and configured so as to process images and signals from the cameras (5a, 5b) and the antenna (6) for assigning each vehicle a series of data which together define a digital fingerprint of each vehicle, wherein the data processing system (8) is provided with an artificial intelligence engine to solve possible incongruences;
• the artificial intelligence engine being configured so as to compare all the detected digital fingerprints and automatically correct any errors in a single data item when all the remaining data referred to the same digital fingerprint and to the same vehicle are consistent with and confirmed by other digital fingerprints;
• the system (1) being characterized in that the data processing system (8) is configured so as to:
• process images acquired by the cameras (5a, 5b) and track each vehicle shot by the cameras (5a, 5b) along a track;
• and
• obtain from the images acquired along the track data which are used by a classification algorithm loaded on the data processing system (8) for classifying the vehicles.
