Remove the dots on the license plate. Why can't the camera get the license plate number?

Although this is only a small point, there is much to be done. The dots are mainly composed of titanium oxide, rare earth metals and rare earth metal complexes. They have special materials and complicated manufacturing process, so it is impossible to forge license plates. So this dot is the key point of license plate anti-counterfeiting.

Generally, there is an infrared detector under the electronic camera to detect infrared rays in a certain range. As mentioned above, the material of the dot is special, and it is also a good infrared emitter. By absorbing the surrounding heat, the dots are converted into infrared rays and radiated, and then the infrared detector can aim at the dots and lock the tracking.

If the camera that the country spent "a lot of money" to build is really as good as you think, every tax you pay will be in vain. Although blocking small spots has an impact on camera focusing, it is certainly not impossible to get a clear license plate number.

Everyone has a love of beauty. License plate is no exception. The first two characters and letters of the license plate correspond to the corresponding provinces and places respectively, and the number or letter combination at the back is the unique number of each car. Separating the two with a small dot can not only make the license plate clear at a glance, but also ensure the aesthetics and practicality of the license plate.

Taking a small spot is an illegal act of deliberately hiding the license plate. According to the traffic safety law, 12 points will be deducted and a fine will be imposed on 200 yuan.
