Abstract
A vehicle identification system identifies vehicles by reading a registration plate and a barcode on the vehicle. The system can include: a registration plate mountable on a vehicle and having alphanumeric characters indicating a vehicle registration number; a barcode mountable on a vehicle, the barcode encoding the vehicle registration number of the registration plate, at least one camera arranged to record in one or more image(s) the registration plate and the barcode; and an analyser arranged to receive the image(s) and automatically extract the vehicle registration number from the registration plate shown in the image(s), and automatically extract the vehicle registration number from the barcode shown in the image(s), the analyser comparing the vehicle registration number extracted from the registration plate with the vehicle registration number extracted from the barcode.

13. A vehicle identification system comprising:
-
a registration plate mountable on a vehicle and having alphanumeric characters indicating a vehicle registration number; a barcode mountable on a vehicle, the barcode encoding the vehicle registration number of the registration plate, and including a checksum to verify that the vehicle registration number has been correctly read from the barcode, a camera arranged to record in one or more image(s) the registration plate and the barcode; and an analyser arranged to receive the image(s) and automatically extract the vehicle registration number from the registration plate shown in the image(s), to automatically extract the vehicle registration number from the barcode shown in the image(s); and
to use the checksum to verify that the vehicle registration number has been correctly read from the barcode,the analyser comparing the vehicle registration number extracted from the registration plate with the vehicle registration number extracted from the barcode to thereby determine whether the vehicle registration number indicated on the registration plate is the same as the vehicle registration number encoded on the barcode, wherein; the barcode includes error correction bits for error correction of both the vehicle registration number and the checksum; and the analyser is arranged to error correct both the vehicle registration number and the checksum using the error correction bits. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21)

22. A method of identifying a vehicle having a registration plate with alphanumeric indicia indicating a vehicle registration number, and a barcode encoding the vehicle registration number and including a checksum and error correction bits,
the method comprising: -
recording in one or more image(s) the registration plate and the barcode using a camera that records both the registration plate and the barcode; analysing the image(s) to extract the vehicle registration number from the image of the registration plate; extracting the vehicle registration number from the barcode shown in the image(s); using the checksum to verify that the vehicle registration number has been correctly read from the barcode; using the error correction bits to error correct both the vehicle registration number extracted from the barcode and the checksum; and comparing the vehicle registration, number extracted from the registration plate with the vehicle registration number extracted from the barcode to thereby determine whether the vehicle registration number indicated on the registration plate is the same as the vehicle registration number encoded on the barcode.
