Automatic Recognition of License Plate Parking System
Design Proposal
License plate recognition systems around the world, high-definition license plate recognition products support non-standard customization.
I. Background
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 vehicle's entry and exit, which can cause valuable time for the owner.
In response to the above phenomenon, WE 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 company's 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.
II. License Plate Recognition Technology
Based on computer technology, image processing technology, and fuzzy recognition, Communication License Plate Recognition (LPR) builds a vehicle's 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.
At present, the high-definition license plate recognition system is mainly used for parking lot management, parking fees, card management, card charge, parking lot vehicle recognition, parking lot license plate recognition, card license plate recognition. Support the languages of many countries. The software operation interface is WINDOWS. The language of the software is English. HD license plate recognition system support includes China, Hong Kong, Macao, Taiwan, India, Saudi Arabia, Iran, Egypt, South Africa, Britain, France, the United States, Germany, Canada, Italy, Mongolia, Russia, Korea, Japan, Australia, New Zealand, Brazil, Argentina, Mexico, North Korea, Ukraine, Poland, Switzerland, Turkey, Southeast Asia, Central Asia, Western Asia, Europe, North America, South America, Africa, the Middle East, Arab countries, and other about 120 countries and regions. The license plates of the above countries and regions can be recognized.
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.

VI.Senseless payment
6.1.Background
Since the first We Chat intelligent parking lot hit the ground in 2015, more and more parking lots have become interested in this new industry solution and have begun to pay attention to the intelligent transformation of parking lots. The solution of We Chat Public We Chat Pay has been recognized. With the rapid development of video recognition technology, the industry has higher requirements for efficiency and user experience, so "license plate recognition withholding" industry new scheme. However, in the process of landing, we found that the scheme of "license plate recognition withholding" has problems such as high threshold for users to open, unable to realize the efficient passage of fees after the first appearance, too scattered service and so on. Therefore, we put forward the "We Chat vehicle owner Service", which is aimed at the vertical domain of vehicle owner travel interface capability.
The "senseless payment" is in the form of "license plate payment", which requires that the account of We Chat (Ali pay, Union Pay) be bound to the license plate in advance, and the car plate number is identified by the camera when the vehicle passes through the toll collection station, and the fees are automatically deducted from the corresponding account. Parking fees directly into the property We Chat (Ali pay, Union Pay) collection account.
The company is the first direct contract with Ten cent non-secret payment parking company, all the free software replacement. Also general in Ali pay, Union Pay's senseless payment and sweep code payment.
2.Interface definition
Vehicle owner service refers to the interface ability designed for the vehicle owner travel scene, through We Chat to realize the link of person, car, service, and to improve the user experience of the industry application. The interface includes, but is not limited to, car-related scenarios such as parking, high-speed, refueling, etc.
3.Function introduction
①The relationship between the account and license plate of We Chat is the key information of the vehicle owner's travel scene. The user binds the license plate at the end of We Chat to establish the relationship between the account and the car. In the case of user authorization or access to the service provider, the corresponding relationship between the user license plate and Open ID is given to the service provider.
②The service of the owner can provide the merchant with the interface ability of We Chat free payment. After the owner service is signed and opened, the user can enjoy the experience of "enjoy the first payment after paying" in the scene of accessing the service of the owner.
③Enjoy the experience of paying first and then pay without feeling, realize the real experience of first passing and then deduct fees, and increase the efficiency by more than 15 times.
