Intelligent management system for license plate recognition, license plate recognition, license plate recognition technology, LPR) with computer technology, image processing technology, fuzzy recognition, based on the establishment of the vehicle feature model and recognition of vehicle characteristics, such as license plate, model, color and so on. It is a specific target object special computer vision system, automatic extraction of license plate image from the image, automatic segmentation of characters, and then recognize the characters. It makes use of the advanced image processing, pattern recognition and artificial intelligence technology, the collected image information processing, real-time automatically and accurately identify the license plate numbers, letters and Chinese characters, and can directly give recognition result, the vehicle computerized monitoring and management become a reality.
We identify the core to learn the abroad and the current license plate recognition algorithm of the essence, and then on the basis of made optimization and improvement, has been greatly improved the speed and the accuracy of the location and identification, especially on light requirements, because too much reliance on environment undoubtedly on the installation and application to form a barrier. Due to the installation location is not fixed, license plate reflective, backlight, backlight and other factors will directly affect the license plate recognition, improved algorithm on the above license plate recognition has been greatly improved.
DLL integrated recognition module form and green free installation for customer integration brings a lot of convenience, online learning and instant join technology can identify new license plate Chinese characters and improve the accuracy rate of recognition.

Anlyses, smashing cars and device can ensure both the vehicle approach or the occurrence of reverse vehicle, just stop at the brake lever, brake lever would not fall under.
System workflow:
1) vehicle entry:
Enter the license plate cameras capture area, vehicle, trigger sense coil.
II, license plate recognition system to automatically capture the vehicle of the image and identify out license plate identification number, then by searching the database drawn vehicle classes.
(3), the screen shows the validity of the car (VIP car or car) or the balance of the stored value, welcome to other cue phrases.
The license plate recognition, voice playing out, Welcome and prompt.
Fifth, if the car is full or a fixed vehicle, gate release, record the vehicle into time. Vehicles across the import, into the parking lot, parking spaces display refresh.
The whole process is completed automatically, without the intervention of the staff. The vehicle has been in the running state, no pause.
2) vehicle leaving:
Enter the license plate cameras capture area, vehicle, trigger sense coil.
II, license plate recognition system to automatically capture the vehicle of the image and identify out license plate identification number, then by searching the database drawn vehicle classes.
Third, display shows the validity of the car (VIP car or car) or the balance of the stored value, amount of charge (temporary car), I wish you bon voyage, prompt.
The license plate recognition, voice playing out, I wish you a I wish you a happy voyage. and prompt.
Five, if the car is fixed to the vehicle, automatic release rod brake machine. The captured image computer out of the car when admission, admission time etc.. If the temporary parking, the vehicle shall suspend payment to leave this IC card with the same scheme. If the vehicle is included in the blacklist, whether temporary or fixed vehicles, the gate will not be opened, while the system will issue a warning signal, notify the staff attention.
The vehicle over the import and export, on leaving the parking lot system down vehicles leave time, parking spaces display refresh.
