Number Plate Scanner

Abstract

Number Plate Scanner (NPS) helps to identify vehicle license plates in an efficient manner without the need for major human resources and has become more and more important the recent years. There are several reasons why their importance has increased. There are a growing number of cars on the roads and all of them have license plates. The rapid development in digital image processing technology has also made it possible to detect and identify license plates at a fast rate. The whole process may be done in less than 50ms. This gives 20 frames per second which is enough to process real-time video streams. Identification of vehicles is useful for many different operators. It can be used by government agencies to find cars that are involved in crime, look up if annual fees are paid or identify persons who violate the traffic rules. U.S., Japan, Germany, Italy, U.K and France are all countries that have successfully applied ALPR in their traffic management.
