Why can the traffic police camera capture the license plate?

Traffic police camera capture principle:

1. coil trigger: the coil is embedded in the ground, and the current change of the induction coil is used to trigger the camera to take pictures when the car passes the ground. This is a project that needs to break ground.

2, radar trigger, the L-shaped pole on the road has both a camera and a radar. When a vehicle passes by, the radar detects the vehicle, thus triggering the camera to shoot. This is a project that often deceives people.

3. The camera directly carries out video analysis (tracking the track according to the license plate). This kind of camera can directly divide the lanes on the video, set the lane operation rules, and the camera can directly analyze the video to capture. This is a seemingly profound project.

Manual camera identification:

Never think that manual identification is backward, but it is very common. Manual identification is generally used to capture illegal traffic on non-motor vehicle lanes. Now, some key intersections have been upgraded and "HD ball machines" have been installed. In order to carry out continuous monitoring and snapshot in all weather or in a specific time period, manual identification is needed.

The way of manual identification is very simple. Generally, the ball simulator equipment can cooperate with the hard disk video recorder to realize remote control of angle scaling and doubling with almost no delay.
