license plate recognition system < / a > camera positioning principle

1. The camera is installed on the side close to the lane in front of the gate host, and the camera line of sight cannot be blocked when the track box rod rises and falls

2. The best recognition distance of the camera is 3-6 meters away from the camera, so keep the car body straight at this distance. If not, move the camera back

3. Ensure that vehicles and pedestrians at the location will not touch the camera by mistake

4. Try to be close to the gate host, but do not affect the use of the gate

5. The side angle and depression angle of the camera positioning position and the vehicle imaging angle shall be controlled within 30 degrees as far as possible, and shall not be higher than 45 degrees, otherwise the recognition rate will be affected. If not, find other positioning points

6. The location shall ensure that the license plate can be photographed no matter which direction the vehicle comes from. If it cannot be met, it shall be assisted by a camera
