[0002] License plate recognition technology, as an important part of the intelligent transportation system, is widely used in parking lots, highways, urban traffic management and other fields. The license plate recognition camera is the key equipment of the license plate recognition system. It captures the license plate image of the vehicle and then uses image processing technology to recognize the license plate number.
[0003] However, in practical applications, license plate recognition cameras are often affected by the external environment, such as dust, rain, snow and other impurities. These impurities adhere to the camera lens, seriously affecting the shooting quality, resulting in a decrease in the accuracy of license plate recognition, or even failure to recognize. Once the lens is contaminated, it needs to be cleaned manually, which not only increases the maintenance cost, but also affects the normal use of the camera if the cleaning is not timely. For this reason, we propose a license plate recognition camera with a cleaning structure. Utility Model Content
