Advantages
- Surveillance of moving traffic; mobile traffic surveillance from a vehicle (by the police).
- Automation of car parks without introducing cards or other identification devices.
- Toll collection on motorways; detection and prevention of non-payers from leaving petrol stations.
- Surveillance of vehicles at border crossings.
Licence Plate Recognition
Licence plate recognition technology functions on the basis of transforming visual information from a camera into a digitised form which enables its further processing in a database system.
Picture Capturing
The picture of a vehicle is captured with a special camera that ensures the recognisability of a licence plate in daylight as well as at night and which is not sensitive to the elements. Additionally, when the licence plate is captured, a panoramic view or a view of the driver can also be captured.
Recognition Technology
Licence plate recognition functions on the basis of the OCR technology (Optical Character Recognition) that is adapted for recognising licence plates. It is possible to recognise one-line as well as two-line licence numbers. Despite external factors (such as damaged, dirty, faded or covered plates), almost 98.7% reliability of recognition is achieved.
Data Processing
The recognised series of characters is entered into the database, and can additionally be furnished with data such as date and time of recognition, reliability, a picture, etc. By means of specially designed applications it is possible to further process such information, search for or sort it, or to manage a car park, etc.
Practical Applications
Licence plates are a form of identification data connected to individual vehicles. It is not possible to borrow a card to access a car park, and there is also the benefit that licence plates are always there when needed. In the event of abuse, the licence plate recognition system enables pictures to be stored from the moment of accessing the facility, which makes it possible to trace abuses.
- Cark park management
- Preventing non-payers from leaving petrol stations
The licence plate recognition system can help lower the number of non-payers from leaving petrol stations by means of notifying the personnel of "repeat offenders". Upon entering a petrol station, a camera records the vehicle, recognises the licence plate, and checks it against the common database. Thus staff can take appropriate measures. - Surveillance of vehicles at border crossings
It is possible to trace stolen or suspicious vehicles upon such entering or exiting the country by means of licence plate recognition system. The system can find a licence plate in the common database and alert officials at the border crossing.
