High-speed ANPR

Vision Catcher's European market leading Automatic Number Plate Recognition system, Talon, was recently launched at the Public Transport show held at Nasrec with great success. The ANPR system was also demonstrated at the recent Airport Show with a great deal of interest from end users, consultants and integrators.

What is ANPR? It is a system that captures high quality, tamper proof evidential images of a vehicle's number plate, which is stored to a database and then matched to prior information of the vehicle and its owner/driver. In all applications each recognised vehicle has a time/date stamp and location number, together with an associated image.

Vision Catcher has secured distributorship of this ANPR solution which has been used successfully by the police in the UK and US for a variety of roles within city centres where it is necessary to monitor vehicles for parking management, congestion charges, pool and bus lane violations. Prior to Vision Catcher taking on the distributorship, the company tested the system trying to trick it by using damaged and defaced number plates, in varying levels of poor light. The ANPR came up trumps recognising the plates and giving us 97% accuracy for all nine South African provisional number plates. In addition, the system has the option of facial ID making it effective for access control situations.

ANPR is used on motorways, toll roads and off-ramps for service stations as it captures number plates at speeds of up to 200 kmph across multiple lanes. It is ideal for policing and remote site police management, which entails remote and onboard vehicular monitoring providing a cost effective means of picking up stolen or unlicensed vehicles. The system can be live linked to a back office facility or central database using the external GSM/GPRS modem. Some of the other obvious applications for Automatic Number Plate Recognition would be car park operators, rental depots, municipalities and transportation companies.
