é—¯Red light camera principle
1, the principle of taking red light photography
The red light electronic eye is a ground pressure type magnetic induction coil. The intersection of the electronic eye is in front of the warning line, and the diamond groove is dug, and the induction coil is buried inside. The electronic eye took a total of 3 photos, one is an instant violation picture, one is a number plate recognition picture, and one is a panoramic picture. Of course, the picture retention time is usually one week. Even if you don't pay the fine, the traffic police uncle will also give you a ticket, and you will be sure to pay the fees before you go to the vehicle.
Say the red light photo principle:
1 When the front wheel of the car is pressed against the induction coil on the ground, take the first picture of your car.
2 When the rear wheel of the car is pressed against the induction coil on the ground, take a picture of the second car.
3 When the vehicle passes the intersection through the induction coil on the ground, the third shot is taken.
From the above principle, you can know that when you have passed the front wheel, it doesn't matter. If you take the first shot, you won't take the second shot if you don't brake. In case you move, the rear wheel is over the line, it doesn't matter if you trigger the second one. Don't cross the road, even if you stop at the warning line opposite the intersection, it will be fine. However, you have to think about your front wheel being photographed, and back, and the result is triggered again!
2, electronic eye features:
Vehicle capture rate - 100% (excluding two-wheeled motorcycles, etc.).
Recognition time - about 1 second (must be much faster than your reaction).
License plate recognition rate - more than 95% during the day and more than 90% at night (still quite high!).
When the green light is going to be on - the system will be turned off 2s in advance, mainly to prevent false shots.
