Parking license plate recognition and debugging

A license plate recognition overview
License plate number recognition, referred to as license plate recognition, also known as license plate number recognition or vehicle license plate recognition or vehicle number plate recognition, is an application of computer video image recognition technology in vehicle license plate recognition, that is, the license plate number is extracted and identified from image information. come out. Vehicle number identification is a very important technology in the intelligent transportation system and can be widely applied to various types of vehicles with exclusive numbers, such as automobiles, trains, and non-vehicle vehicles.
Vehicle number identification has achieved a wide range of applications, such as electronic *, * bayonet, highway speed and toll collection, parking management, Skynet monitoring, car special parking management, especially in electronic * and * bayonet and highway In other areas, the license plate recognition function has basically been established. The parking lot has also entered the stage of extensive application in China since 2012. By the end of 2013, it is estimated that it has reached a coverage rate of 10%. The application of Skynet monitoring and special train parking has only just begun.
The general principle of license plate number recognition is as follows: It is divided into four modules: image acquisition, license plate positioning, character segmentation, and character recognition. Then software programming is used to implement each part, and finally the license plate is identified and the license plate number is output.
The license plate recognition integrated camera is an intelligent, high-definition vehicle license plate recognition integrated product specially developed for the parking lot industry. It is an exclusive combination of license plate recognition, camera, front-end storage, fill light, etc. It adopts high-definition wide dynamic CMOS and TI DSP. Computing power up to 6.4Ghz. Based on the license plate automatic exposure control algorithm, excellent imaging. With excellent performance, versatility, high adaptability, strong stability and other characteristics, it is a good application form of the license plate recognition function of the parking lot management system.
