car license plate recognition technology as open traffic via third eye by intelligent transportation and the government attaches great importance to, to alleviate the pressure of the traffic management, especially the static traffic plays a very important role.And as the 21st century the core subject in the construction of the urban traffic information highway, to a great extent, promote the rapid development of intelligent transportation.
so, license plate recognition in intelligent transportation how plays a role?
in intelligent transportation applications, in addition to extract the information such as vehicle flow, how convenient vehicle identification is also very important.In many vehicle identification ways, license plate recognition for its outstanding performance in the application of won general recognition of the industry.
take a look at the working principle of license plate recognition:
license plate recognition is the use of acquisition vehicle dynamic video or static image for license plate number, license plate color automatic pattern recognition technology.The core of the technology including license plate localization algorithm, license plate character segmentation algorithm and optical character recognition algorithm, etc.A complete license plate recognition system should include vehicle detection, image acquisition and license plate recognition and so on several parts.When vehicles detection part to arrive trigger image acquisition unit, collect the current video image.License plate recognition unit of image processing, locate the license plate location, then came out of the license plate character segmentation, which can identify the license plate number output.
license plate as a vehicle to the identity of the logo has uniqueness, usually no two cars in the world use the same legal license plate.Although there are two cars abroad use the same license plate number, but it must license plate color.
as a vehicle identification signs, license plate has a very standard coding way, provides a convenient conditions to identify.For each type of license plate, the license plate format type is unique, as in China’s ordinary civil car, license plate of the first character is Chinese characters, and for the province’s vehicles referred to as ";The second character for letters and different letters represent different cities.What color is not the same kind of vehicle use license plate also have strict rules, such as military special vehicles are used white plates, blue plates should be used in civilian cars and so on.
the license plate location is relatively fixed, installed in the front and the end of vehicle fixed position, is very obvious, also convenient take pictures collected.
according to the uniqueness of the license plate, license plate recognition technology will be widely used in electronic parking charge system, highway toll and parking fee, parking lot and entrance and exit to a neighborhood application of license plate recognition technology is mainly used to record the vehicle’s license plate number, license plate color, access time, the realization of automatic management of vehicles, in order to save manpower and improve efficiency.
as one of the important core technology in the intelligent traffic management system, the license plate recognition will be as open traffic through the inner eye, to the parking lot and the major parking toll station service.Make people’s life more convenient parking, orderly.
