What Are the Factors That Affect the Recognition Success Rate of Entrance and Exit License Plate Rec

The entrance and exit license plate recognition vehicle management system will be used in places with a large number of traffic flow. During the use of the equipment, there will inevitably be problems such as abnormal system recognition and decline in success rate. What are the factors affecting the success rate of recognition? 1、 The license plate recognition camera is placed incorrectly, and the license plate recognition camera is installed in an appropriate range, because if the camera has a recognition range, the license plate recognition will not be recognized beyond the specified distance. 2、 If the vehicle speed is too fast, it will affect the license plate recognition camera to capture the license plate image and affect the recognition success rate. Generally, the entry and exit speed of vehicles should be ≤ 10km/h。 3、 The missing of the appearance part of the license plate, the paint falling off of the license plate, serious wear and the cover of the license plate surface by pollutants will reduce the recognition effect and lead to problems in recognition. 4、 Changes in the natural environment, rain, snow, fog and other weather affecting light visibility, and the inability of the license plate recognition camera to obtain a clear image will also affect the recognition success rate. 5、 The rear vehicle attempts to follow the front vehicle into the license plate recognition. The vehicle management system usually only supports one shot per vehicle, and the following the front vehicle into the system will not be recognized.
