one.Overview of mobile license plate number automatic recognition and detection system
The license plate number is the only “identity” of the vehicle, and it is an important information of the motor vehicle. The automatic license plate recognition technology realizes the automatic registration of the vehicle license plate number and color, and can complete automatic monitoring, automatic registration, automatic statistics, automatic Verification, automatic comparison, automatic alarm, automatic release and many other functions. With the rapid increase in the number of cars, the requirements for intelligent vehicle management are getting higher and higher, and the application of automatic license plate recognition technology is becoming more and more extensive.
This system is an intelligent product that integrates multiple technologies such as image acquisition/processing/recognition, database, automatic control, wireless communication, satellite positioning, electronic maps, voice synthesis, etc. It consists of vehicle cameras, vehicle hosts, GPS and wireless communications, etc. It is composed of a unit and installed on a patrol car. It can be used for real-time recognition and detection of the license plate numbers of moving vehicles and fixed vehicles, and quickly and accurately identify lost vehicles, hit-and-run vehicles, vehicles that have not been inspected annually, vehicles that have not paid road maintenance fees, and have violated regulations. Recording vehicles, vehicles that should be scrapped, fake license plates and other vehicles involved or key monitored vehicles are powerful means to combat motor vehicle theft, hit-and-run crimes, and provide a strong guarantee for maintaining public order and strengthening public security traffic management.
This system can also be used for automatic detection and warning of vehicles outside the unit or group.
two.Mobile license plate number automatic recognition and detection system composition
The system consists of vehicle front-end equipment and central system equipment.
The vehicle front-end equipment is composed of a vehicle camera, a vehicle host, GPS, wireless communication, and voice synthesis. The vehicle-mounted camera captures the image information of various vehicles, the vehicle-mounted host performs intelligent processing, automatically and quickly recognizes the vehicle license plate, and performs database query and comparison and data display, and provides alarm information (voice synthesis prompt).
three.Main functions of mobile license plate number automatic recognition and detection system
* Image capture and license plate number recognition: The system automatically captures the image of passing vehicles captured by the camera and automatically recognizes the license plate number.
* Database query and comparison
1. The system will automatically and quickly compare with the on-board database, and can automatically alarm.
2. The database can be “blacklisted” vehicles (lost vehicles, hit-and-run vehicles, vehicles that have not been inspected annually, vehicles that have not paid road maintenance fees, vehicles with violation records, vehicles that should be scrapped, false license plates, and other vehicles involved in the case or key monitoring vehicles, etc.), If the search result of the recognized license plate number is the same as that in the database, the system will automatically alarm (in this case, it is to grab a specific vehicle).
3. The database can also be an internal vehicle of a certain unit or a certain group. If the search result of the identified license plate number is different from that in the database, the system will automatically alarm (this situation is to prevent other vehicles from entering a certain area or a certain range).
* Voice prompt: When alarming, the system will automatically prompt the alarm information (license plate number, alarm type, etc.).
* Remote automatic database update (wireless communication): Use the GPRS data service of the mobile public network to realize the automatic real-time update of the vehicle database and the central database (only the updated data part is transmitted): the processing data of each patrol car will be transmitted to Center; any changes in the central database will also be communicated to each patrol vehicle in time, avoiding missed catching or catching the wrong car, and is convenient to use; this method is especially practical when there are many patrol vehicles.
* Wireless transmission of alarm images: Using the GPRS data service of the mobile public network, the captured images of blacklisted vehicles or specific alarmed vehicles can be transmitted to the center in time for rapid processing.
* Satellite positioning and electronic map: The system has a satellite positioning function, and the position signal is transmitted by GPRS; on the electronic map of the central computer, the precise position of the patrol vehicle can be displayed in real time, which is convenient for dispatching and management.
Four.Features of mobile license plate number automatic recognition and detection system
The advantages of the camera installed in the car: strong protection ability, reliability, etc.; fixed installation, fixed focus lens, free operation, high efficiency and good effect; the application of GPS and wireless communication means can communicate and determine the location in real time.
