License Plate Recognition Management System: All in One License Plate Recognition Machine in Parking

License plate recognition management system: the application of all-in-one license plate recognition machine in the parking lot management system the application of all-in-one license plate recognition machine in the parking lot management system what special use scenarios will the license plate recognition system encounter in the parking lot? The current license plate recognition system mainly extracts vehicle information through the license plate recognition camera, The pictures captured by the camera are relatively complex due to the interference of the external environment, so the speed, clarity and accuracy of taking out the license plate number are greatly affected. In order to improve the resolution and recognition ability, we should deal with different scenes from the algorithm layer. So what special usage scenarios will the license plate recognition system encounter in the parking lot? Large angle recognition large angle recognition is a difficult point in license plate recognition system technology in parking lot environment. Because the license plate recognition system is difficult to capture the rectangular license plate of the vehicle at a large angle in the parking lot, the license plate image obtained is usually not a rectangular image, so the deformed image needs to be corrected. License plate imaging distortion caused by large angle is one of the recognized technical problems in license plate recognition. 2 The recognition speed will be affected by the picture pixels.

The farther the license plate recognition camera is from the license plate, the smaller and closer the pixels are, the larger the pixels are, and the lane of the parking lot is shorter than that of other scenes. Moreover, the recognition of the current license plate recognition system is real-time. It is a typical contradiction to support the recognition of license plates with large pixel width under the condition of ensuring rapid recognition. Generally, the license plate pixels are too wide, and the recognition speed must be very slow. If you want to recognize fast, the license plate pixel width must be within a reasonable range.

As we all know, the parking lot management system can well manage the order of the parking lot, effectively improve the utilization rate of the limited parking space in the parking lot and alleviate the parking problem. For this reason, the parking lot management system has been widely used in major, small and medium-sized cities all over the country. Now let's introduce the application of all-in-one license plate recognition machine in parking lot management system. [license plate recognition all-in-one machine] the license plate recognition all-in-one machine is an important part of the parking lot intelligent management system, which is composed of license plate recognition, camera, front-end storage, lighting, etc. In practical application, the all-in-one license plate recognition machine captures images through the camera, automatically recognizes the license plate number, license plate color and vehicle type when the vehicle enters and leaves, records the entry and exit time and other information of the vehicle, and combines with the control equipment such as automatic door and road gate to realize the automatic management of the vehicle. [all in one license plate recognition machine] the equipment is applied to the parking lot, which can not only realize automatic timing and charging, but also automatically calculate the number of available parking spaces and give tips, so as to realize automatic management of parking charges, save manpower and improve efficiency. At the same time, it can also effectively maintain the order of the parking lot. Internal vehicles can enter and leave without parking, while external vehicles only need to pay for entering and leaving the site, without cumbersome processes such as card / ticket collection.
