Automatic Number Plate Recognition Image Capture systems are designed to read vehicle licence plates day and night, in the most demanding conditions. We provide image capture systems which can be supplied with a range of different internal camera and IR illumination options offering unmatched flexibility - suitable for any ANPR application including mobile, fixed and long range ANPR.
The new generation of ANPR cameras can now recognise the make and model of vehicles and match them to their licence plate.
The ANPR algorithm consists of two basic parts:
The Make and Model Recognition system enables automatic description of the vehicle concerning its type (passenger car, van, truck, bus), make (e.g. Fiat, Volvo, Scania) and model (e.g. Ford Focus, Mercedes Atego, Volkswagen Transporter). The subject to the analysis is the image of the front of the vehicle, that is the outline of the bonnet, lights, grille, or bumper.
The image is converted in a complex, nonlinear process of parameterisation into a descriptor, which is compared with the reference database containing patterns of several thousand different vehicles. In the current database there are 1,043 different vehicle models and the number of the vehicles collected exceeds 2,500 (taking into consideration the model versions).
These new cameras are currently being trialled across petrol stations throughout Ireland to decrease the likelyhood of drive-offs. A Watchlist can be created detailing cloned licence plates and stolen vehicles, with access given to the local police force.
A vehicle presence trigger input is also provided for the most demanding applications, for example, taking an overview picture of a vehicle with a missing plate. These ANPR cameras can be integrated into a wide variety of systems and connectivity can be over GPRS, EDGE or 3G. A GPS unit can also be fitted allowing very high accuracy times and delivery of information. Our ANPR cameras are fully web-enabled and can be configured and monitored from a standard web-browser. External devices such as DSRC (dedicated short range communication), radar, weigh-in-motion (WiM) or ticketing systems can be integrated into the system. A flexible interface allows these devices to trigger the camera and append information to the data set which the camera generates for each vehicle.
