The current license plate recognition system mainly extracts vehicle information through the license plate recognition camera, and the pictures captured by the camera are relatively more complicated due to the interference of the external environment, so the speed, clarity and accuracy of taking out the license plate number are greatly affected by it. In order to solve the problem of improving the recognition ability, it is necessary to deal with different scenes from the algorithm layer. So what are the special usage scenarios that the license plate recognition system will encounter in the parking lot? www.coma-carparking.com
What special usage scenarios will the license plate recognition system encounter in the parking lot?
1. Wide-angle recognition
Large angle recognition is a more difficult point in the license plate recognition system technology in the parking lot environment. Since the license plate recognition system is difficult to photograph the rectangular license plate of the vehicle at a large angle in the parking lot, the license plate image obtained by it is usually not a rectangular image, which requires correction of the deformed image.
Second, the recognition speed will be affected by the picture pixels
The farther the license plate recognition camera is from the license plate, the smaller the pixels; on the contrary, the closer it is, the larger the pixels. The parking lot is shorter than the lanes of other scenes, and 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 a large pixel width under the condition of ensuring rapid recognition. Usually the license plate pixels are too wide, the recognition speed must be very slow, and if you want to recognize fast, the license plate pixel width should be within a certain range.
