Inquiry and Quotation of License Plate Recognition System - Tigerwong

The license plate recognition system extracts the image of the license plate, which refers to determining the position of the license plate in the captured image. Then segment the characters in the license plate. The difficulty in locating the license plate area mainly comes from the collected images. Due to the diversity of the collected license plate images and the influence of many factors, such as rain, fog and light, the quality of some license plate images varies at different levels. Generally, the background of the collected images is very complex, The collected image is a picture collected in high-speed movement, so the position of the license plate in the picture is not fixed, and the size of the license plate is also different. All the above interference factors bring difficulties to the license plate area location and character segmentation, thus affecting the recognition rate of the license plate. It will also lead to the contradiction between the high resolution of the image and the recognition speed. The advantages of HD are obvious, from analog camera to HD camera. However, everything has two sides. License plate recognition is mainly reflected in: due to the wide coverage of high-definition pictures, multiple license plate recognition may appear in the pictures at the same time. This requires a high speed of license plate recognition. The license plate recognition system has too large HD video stream code, and the processing speed will be too slow due to the excessive demand for the resource occupation of the recognition system, which may lead to the phenomenon of missing vehicles, and it is difficult to improve the capture rate of vehicles and the accuracy of license plate recognition. This can be seen from the support of technology and policy. To fully realize smart travel, it is also necessary to include a series of post services, such as intelligent parking. According to statistics, on average, a car is in driving state for only one sixth of the time every day, and can't be parked at other times. In addition to the road, the place most closely related to all cars should be the parking lot. Not only need to be able to "open" but also need to "stop". In the future, to realize smart travel, smart travel should realize a complete process. Only the intelligent vehicle license plate recognition system is far from enough. It also needs charging service and intelligent parking lot to make up for the missing links, so as to jointly realize the complete ecological closed loop of intelligent travel.
