Advantages of electronic license plates:
1．High recognition accuracy: Based on RFID technology, the recognition rate of electronic license plates can be achieved at a high level, which is difficult to achieve with traditional optical license plate recognition;
2 Fast recognition speed: Due to the complicated road traffic environment and fast speed, the electronic license plate is required to have a very fast reading speed;
3．Accurately locate the vehicle information: When installing the electronic license plate, write the vehicle related information to avoid the occurrence and detection of the company's private use, theft of the vehicle, etc.;
4 It is easy to install, stable, and has strong anti-interference ability, and is not affected by special weather.
Limitations of electronic license plates:
1 Visibility, which is the most important information in the handling of illegal information by the public security and traffic control (for example, today the traffic police read the speeding violations in Nanjing Xinjiekou through the electronic license plate, but the actual situation is that you have not Driving on the road, then the real situation is whether your vehicle is illegal, or other vehicles have stolen your electronic license plate, no image, can not be verified);
2 The technical standards of electronic license plates are difficult to determine, and the maintenance cost is high in the later stage: electronic license plates involve personal information of various vehicles in the country, involving personal privacy. The implementation of this technology, considering safety, should be implemented by national unified standards. It is impossible for any company to participate as in the previous electronic police or bayonet, but in the face of such a large number of vehicles, maintenance is definitely a difficult job;
3 reading distance: Since the electronic license plate application is RFID technology, there must be limitations in reading distance. In some specific scenes, it is difficult to identify the vehicle information by installing an electronic license plate reading device, and the conventional image recognition , you can achieve the requirements of large shooting distance by configuring the resolution of the lens and camera;
4Physical Accuracy: Especially in the field of electronic police, the traditional electronic police shooting violations require three close-up pictures of vehicles, which are in front of the parking line, behind the parking line and close-up of the vehicle, and have to be associated with signal lights, and electronic license plates. It is difficult to meet the above requirements.
