Car Park License Plate Recognition Is Diversified, and the Future Development Prospect Is Promising

With the gradual increase of vehicles, people pay more and more attention to the parking industry. The fully functional and convenient parking lot system is particularly loved by people. In order to adapt to the good treatment of the majority of riders in the parking lot, some parking lot system manufacturers have introduced many advanced technologies, such as license plate recognition, mobile payment and other functions, In order to make it easier for motorists to be accurately recognized in and out of the parking lot, many new functions will be added to the license plate recognition technology of some parking lots. Let's take a look at the diversified license plate recognition of parking lots. With the development of the parking industry and various market demands, the license plate recognition of the parking lot is more and more widely used.

Through the automatic recognition, automatic login and automatic comparison of the license plate number, the system can automatically open the gate, automatically charge, automatically verify the user's vehicle identity, automatically distinguish internal and external vehicles, and automatically calculate the number of vehicles Many intelligent functions such as automatic alarm are divided into two categories: software identification and hardware identification. Software recognition: it is obvious that the meaning of the word can be understood through the software. The captured pictures are recognized and processed by installing a supporting license plate recognition software on the computer. Its working mode is to continuously capture multiple photos through the camera, select the clearer one, and then process the characters through the computer software to realize the number plate recognition. Because multiple pictures need to be captured for each recognition, the speed of soft recognition is slow, and the system also has high requirements for the captured pictures, which must be very clear to achieve the desired effect.

The system has high requirements for on-site environment and commissioning quality, and is not applicable in many occasions where the environment is not optimistic. The placement of equipment is very important. Hardware recognition: popular explanation is to process a series of characters of captured pictures through independent hardware equipment; At present, the hardware recognition in the parking lot system industry is also divided into two types, namely, with a separate license plate recognition instrument and front-end hardware recognition. The front-end hardware recognition is mainly used. At present, the main thing on the market is the integrated license plate recognition machine, which embeds the traditional separate license plate recognition instrument into the camera to realize the integration of front-end hardware and camera, and perfectly realize a series of work, such as image capture, video stream transmission, character recognition, gate lifting and so on.

The license plate recognition system also has two trigger modes: peripheral trigger and video trigger. Peripheral trigger: it means that the coil, infrared or other detectors are used to detect the vehicle passing signal. After receiving the vehicle trigger signal, the license plate recognition system collects the vehicle image, automatically recognizes the license plate and carries out subsequent processing. The advantages of this method are: high trigger rate and stable performance; Disadvantages: it is necessary to cut the ground and lay the coil, which requires a large amount of construction. Video trigger: it means that the license plate recognition system uses the dynamic moving target sequence image analysis and processing technology to detect the vehicle movement on the lane in real time, capture the vehicle image when it is found that the vehicle passes, recognize the vehicle license plate and carry out subsequent processing. The video trigger mode does not need the help of coil, infrared or other hardware vehicle detector.

The advantages of this method are: convenient construction, no need to cut the ground to lay the coil, and no need to install vehicle inspectors and other parts; Disadvantages: due to the limit of the algorithm, the trigger rate and recognition rate of this scheme are much lower than those of external triggers. With the continuous development of car parking management system, in the future, with the acceleration of urbanization in China, as an important core of intelligent traffic management system, license plate recognition system will be further supported and developed, license plate recognition technology will be more and more perfect, and can better serve people's daily life, The use of license plate recognition parking lot system makes the parking lot realize unmanned management, which is also the potential development direction of intelligent parking lot in smart city in the future.
