Vehicles with a large number of traffic flow will use the automatic license plate to identify the vehicle management system. In the process of using the equipment, system identification anomalies will occur and the recognition rate will be reduced. So what factors affect the recognition rate?
First, the license plate recognition camera is placed incorrectly.
The license plate recognition camera should be installed in the proper range. Because the camera has a recognition range, the license plate recognition cannot be recognized beyond the specified distance.
Second, the car speed is too fast
If the vehicle speed is too fast, it will affect the license plate recognition camera to capture the license plate image and the recognition rate.Therefore, the general vehicle access speed should be ≤10km/h.
Third, the license plate is partially missing
When the license plate is lacquered, the wear is severe and the surface of the license plate is blocked by contaminants, the recognition effect is reduced and resulting in problems in identification.
Fourth, Environmental change
Rain, snow, fog, etc. affecting the visibility of light, the license plate recognition camera can not obtain a clear image will also affect the recognition success rate.
Fifth, The car behind tried to follow the car ahead
The license plate recognition vehicle management system usually only supports one car one pole, the following car entry system will not be recognized.
