The research on intelligent vehicle access management system is to develop a set of advanced, applicable, economical and reliable intelligent vehicle access management system based on modern advanced high-tech technology and products. The development of the license plate system enables intelligent management of the vehicle. At present, for the vehicle monitoring and management of the city, the system for applying the license plate is very extensive. For example, a large parking lot is now using a smart parking payment system, and it is also possible to track the stolen car. The development and application of the license plate system improves the safety of the transportation system, reduces traffic congestion, and realizes intelligent traffic management, which can promote social informationization and promote social and economic development.
Therefore, the research and development of high-performance license plate intelligent identification system has a good market prospect, has a large application space and potential, and plays a positive role in promoting the planning and development of China's transportation system. This study focuses on the research of intelligent vehicle intelligent vehicle access management system. Its purpose is to develop and complete an embedded intelligent vehicle access management system that integrates video acquisition, vehicle detection, license plate recognition, voice report, intelligent analysis of recognition results, automatic alarm, remote duty and remote monitoring. The whole process does not require manual processing. The most important thing is that it does not require the owner to take magnetic strips or swipe cards. This will not delay the owner's time and improve the efficiency of vehicle access management.
At present, the automatic recognition of license plate is more and more widely used in the parking system. The automatic recognition of the license plate is an automatic pattern recognition technology that uses the dynamic video or static image of the vehicle to collect the license plate number and license plate color. A complete license plate recognition system should include vehicle detection, image acquisition, and license plate recognition. The core of license plate automatic identification system technology includes license plate location algorithm, license plate character segmentation algorithm and optical character recognition algorithm.
The image acquisition unit is triggered when the vehicle detection portion detects that the vehicle arrives, and the current video image is acquired. The license plate recognition unit processes the image, locates the license plate position, and then divides the characters in the license plate for identification, and finally forms the license plate number output. At present, there are three main application modes of license plate recognition in the parking lot management system: video recognition mode, ground sense coil recognition mode, and video + ground recognition mode.
First, the video recognition mode
The video triggering advantage is that there is no need to install the ground sense coil, and the engineering quantity is small. When the vehicle enters the video recognition area, the camera automatically recognizes the license plate information through the moving image of the vehicle while providing analog trigger recognition. The disadvantage is that it is impossible to output images for unlicensed cars and it is easy to miss the car. If the license plate result is not recognized, you can manually click on the analog trigger to identify it.
Second, the sense of the coil identification mode
The ground sense coil is triggered. Under normal circumstances, there will be a speed reducer at the position about 10 meters before the parking lot gate. The vehicle will decelerate through the speed reducer to set aside time for identifying the license plate. The vehicle enters the identification area and triggers the ground sense coil. The camera is automatically commanded to capture, and the license plate is recognized by the character detection, and the gate is released. The advantage of the ground-sensing coil triggering license plate recognition is that the trigger rate is high, the car is not easy to leak, and the performance is practical and stable, and the image record can be output for the unlicensed car. The disadvantage is that it requires a sense of construction and installation, and the amount of engineering is large.
Third, video + ground recognition mode
This method is an upgraded version of the first two modes. The video plus ground recognition mode is identified by video recognition mode and uploaded by the ground trigger mode. Compared with the sense of coil recognition and video recognition mode, the video + feature recognition mode can provide faster recognition speed and higher recognition rate. The recognition mode of video + ground flexible switching is the best identification mode for current application flexibility. The identification area and output area are delineated by software, and the position of the license plate output can be freely set according to the customer's site environment. The problem of fire output too early. When an unlicensed car travels to the output area, it is easy to record unlicensed car information.
Although the license plate recognition market is very large in the smart parking system, it is not easy to have a place in the parking lot charging system. Based on the enterprise itself, if it cannot break through from the homogenized parking equipment product line, perhaps Entering the service market is another good choice, but the early investment in the intelligent parking lot management system service market is different from the hardware market. The early investment is large and the profit recovery is slow. It is also the risk that all enterprises must consider. The process of modernization of social development is very fast, and there are more and more cars in the city, resulting in an increasing traffic volume in various parking lots. Naturally, everyone will have the need for intelligent parking management, efficiency and security. As a result, smart parking system products came out and stopped in modern times.
Playground management plays an increasingly important role. The intelligent parking lot management system uses modern communication science and technology as well as mechanical and electronic. The license plate recognition system integrates control hardware and software. With the development of science and technology, the community license plate recognition, parking lot management system is also changing with each passing day. In order to meet the needs of the development of its parking lot, the manufacturer of the license plate recognition system has developed a parking lot intelligent management control system for this demand.
