There is some technology in the automatic number plate recognition (ANPR) to use the recognition optical character on vehicles to read their image in the registration plates for creating location data in vehicles. Some are existing in the closed-circuit television, road-rule camera enforcement cameras, or some cameras are specially designed for the task. The police force to be used in ANPR around the world for law enforcement purpose, it may include the registration vehicle or licensed. It may also use the electronic toll condition and pay-per-use roads. They are some methods for cataloging traffic movement in the example of highway agencieslpr system can work over the ANPR system.
The automatic license plate recognition is used to store the images by the camera in the picture taking at any time as well the text from the license plate in the configurable of the photograph to be stored for the driver. There are commonly used in the infrared lighting allow the camera to take the picture at any time day or night. ANPR technology is a must to take the account plate variation from one place to another place. There are some primary issues about ANPR. The invention of ANPR is 1976 in the scientific development of the police branch in Britain. There are some industrial are ready to give contracts in the EMI electronics first. It has some recognition of the computer system.
There is an early time in their development system on the A1 road ar the tunnel of Dartford. The detection of the stolen car is the first arrest is made in 1981. This is not widely used in the new development in cheaper and easier to use some software during the 1990s to be a pioneer. There is some collection in the ANPR date for future use it is documented in the early 2000s. ANPR is being helped to solve the murder documented case which is occurred in November 2005. There is a vital role in locating and subsequently killers. There is an acceptance of the software to run the system on the standard hardware computer home to be linked in this application or database.
Development and components
There are some manipulation in the series of the image in the technique to normalize and images to enhance the number plate and there is some optical character recognition for the extraction of alphanumeric license plates. There are two basic approaches in the ANPR system like one allows the entire process to be performed in the line location and other images should be transient in many lines. It performs the location and performs the process of OCR at a later time. They easily transmitted in the information to be in the late retrieval in the arrangement order. There is a large number of the type used in serve farm to handle the high workloads. This is the forward images in the requirement of the remote server and to require the larger bandwidth of media transmission. The enforcement of the road-rule in the camera are existing in the CCTV cameras as well as mobile units and some vehicles are usually attached. There is some infrared camera is used to take a clear image of the license plate.
