How to Develop License Plate Recognition System Under Big Data_ Taigewang Technology

With the improvement of people's living standards, there are more and more vehicles. In crowded cities, the contradiction between the number of parking spaces and the demand is becoming increasingly prominent. Urban public parking lots are increasingly unable to meet the growing parking demand. The difficulty of parking has become a bottleneck restricting the management and economic activities of large, medium and small cities in China. How to meet the vehicle parking demand of car owners, It has become an urgent problem to be solved. The development of Internet plus makes it necessary to build scientific, planning and systematization intelligent car park. In recent years, with the development of Internet technology, intelligent parking lots have developed on a large scale. The intelligent parking lot system mainly realizes the infrared detection module of parking lot, the automatic control module of parking lot gate and the display module of parking lot. When the owner drives into the parking lot, the system gives the vehicle model and vehicle information through the card swiping system. The control center compares the returned vehicle information with the existing vehicle database, calls the gate control module to issue a control command, and the infrared sensor under the parking space transmits the spare vehicle amount information to the control center, The control center selects the parking space suitable for the vehicle according to the vehicle model and guidance system, and instructs the owner how to park through the display screen. However, with the improvement of the pace of life, people need to know more urgently where there are free parking spaces? Where can I park quickly? Where can I pay the parking fee quickly? The birth of pure license plate recognition system combines the resources, data, fund management and other information of the parking lot through Internet technology, big data and cloud computing, extracts and recognizes the vehicle license plate number entering the parking lot from the complex environment, and recognizes the vehicle number through license plate number extraction, image preprocessing, feature extraction, license plate character recognition and other technologies Color information, etc., combined with the license plate recognition system to identify vehicles. When passing vehicles pass through the crossing, they do not need to stop, that is, they can realize automatic vehicle identification and automatic charging. In the parking lot management, in order to improve the traffic rate of vehicles at the entrance and exit, the license plate recognition system leaves an unattended fast track for fixed vehicles in the parking lot, which changes the management mode of the parking lot. In order to improve the traffic efficiency of the entrance and exit of the parking lot and reduce the time for vehicle parking, card collection and central payment, a three-dimensional parking lot system is formed, so as to realize the intelligent management of the parking lot.
