Smart LPR License Plate Recognition Car Parking System For Parking Lot Management
With the continuous development of science and technology economy, automobiles have begun to popularize ordinary families, and a large number of vehicles have brought new problems to the management of parking lots. Traditional car park management mainly distributes IC cards to vehicles entering the parking lot to record the time of entry and exit of vehicles. As the main basis for billing, regardless of whether it is a fixed vehicle or a temporary vehicle, access to the parking lot must be done at the entrance and exit of the parking lot in order to enter or exit the parking lot. In the field, this type of management often leads to traffic jams during busy periods of the vehicles entry and exit, which can cause valuable time for the owner. In response to the above phenomenon, our company Shenzhen WenCan Technology Transportation Equipment Co., Ltd. has launched a new management concept, using the license plate recognition technology to replace the traditional IC card technology, to solve the car import and export traffic congestion caused by the need to stop the card when entering and leaving the car. This system is a new type of barrier-free parking lot management system that uses our companys license plate auto-recognizer controller and software module to enter vehicles without parking. The driver does not need to park at the entrance and exit. When the vehicle enters the entrance to the parking lot, it automatically captures the photos of the vehicle and identifies the license plate number. The license plate number, color, license plate characteristics data, and entry time information are transmitted to the management computer. Parking lot provides users with a brand-new service mode.
Based on computer technology, image processing technology, and fuzzy recognition, Shenzhen WenCan Technology Communication License Plate Recognition (LPR) builds a vehicles feature model and identifies vehicle features such as number plates, vehicle models, and colors. It is a special computer vision system that targets a specific target. It can automatically extract license plate images from an image, automatically divide characters, and then identify characters. It uses advanced image processing, pattern recognition, and artificial intelligence technology. The collected image information is processed, and the digital, letter and Chinese characters of the license plate can be automatically and accurately recognized in real time, and the recognition result is directly given, so that the computerized monitoring and management of the vehicle become a reality.
The New LPR Technology has absorbed the advantage algorithm domestic and abroad ,on the basis of this, the optimization and improvement are made.The speed and accuracy of recognition have been greatly improved.Especially for lighting requirements,changed the defective of highly reliance on the environment that is undoubtedly an obstacle to installation and application. Due to the uncertainty of the installation location,plate reflection, backlight and other factors will directly affect the recognition of the license plate.The improved algorithm has greatly improved the recognition of the above license plates.
The integrated recognition module form and green installation-free of DLL have brought a lot of convenience to customer integration. Online and timely learning, and real-time adding technology can recognize new Chinese characters of license plate and improve recognition accuracy in real time.
The system software is a graphical international version of the application based on windows 98 + windows 2000 platform, using a stable, reliable and large database software Microsoft SQL server 7.0 or Microsoft SQL server 2000.With friendly interface, simple operation and perfect function. It mainly includes login, maintenance, files, vehicles, monitoring, recording, reporting, exiting and other modules.
