debugging requirements for the installation of integrated license plate recognition machine < / a >

1. The road width shall be controlled within 4m as far as possible

2. In the entrance and exit license plate capture and recognition system, the camera generally adopts the side mounted method. It is recommended to use a 1.2m vertical pole with a diameter of 50mm or 76mm. The installation height of the camera is about 1.6m, which is installed from the top

3. The installation position of the camera is 3 ~ 4m away from the central axis of the ground induction coil to ensure the appropriate capture distance. It depends on the lens. The central axis of the trigger coil is the focus position of the camera

4. The fill light and the camera are installed on the same vertical pole, and the installation height is 30 ~ 60cm above the ground. During light debugging, pay attention to the position between the license plate and the ground when triggering the ground induction coil

5. It is recommended to set up a deceleration belt about 0.5-1m away from the recognition area. The deceleration belt is not installed. If the vehicle travels too fast, it will affect the license plate recognition rate
