近In recent years, it is said that electronic license plate is about to replace ordinary license plate and video license plate recognition is useless. It is true that electronic license plate does have many advantages. It seems to be the general trend that electronic license plate replaces ordinary license plate, but isn't it the useless place for video license plate recognition?

Electronic license plate is an application based on the subdivision, extension and improvement of Internet of things passive radio frequency identification (RFID) technology. Its basic technical measures are: using the technical characteristics of RFID, such as high-precision identification, high-accuracy collection and high sensitivity, an electronic license plate label is installed on the motor vehicle, the RFID electronic license plate is used as the vehicle information carrier, and the data on the electronic license plate of each motor vehicle is collected or written when the road section is equipped with an authorized RFID reader To all kinds of comprehensive traffic management purposes.

Indeed, as the product of RFID technology to a certain extent, the development prospect of electronic license plate is very considerable. With the rapid development of the city, the increasing population and the increasing pressure of traffic on the society, electronic license plate can solve a series of traffic problems in today's society. Electronic license plate can be widely used in parking lot management, vehicle traffic management, vehicle scheduling management, port and wharf vehicle management, vehicle intelligent weighing management, public transportation management, illegal vehicle inspection management, customs vehicle clearance management, vehicle exhaust emission control management, etc. it is the core component of future intelligent transportation.

But does the development of electronic license plate mean that video license plate recognition will become a chicken ribs technology of "tasteless food, a pity to discard"? Of course, the answer is No.

Although the electronic license plate has a wide range of application functions, but it can not meet all the needs of vehicle recognition, the future vehicle recognition market still needs video recognition technology as a supplement. Although electronic license plate can achieve 100% recognition that video recognition technology can't achieve through radio frequency technology, it also has some problems.

First of all, the nature of the electronic license plate determines that its construction and promotion can only be led by the government. However, it will take a long time for the electronic license plate technology and supporting card reading facilities in the initial stage to form a sound recognition network. Video license plate recognition has been developed for a long time, and it has become mature both in technology and market. For example, in today's video license plate recognition market, there has been a dominant license plate recognition technology supplier that is perpendicular to different fields. For example, eye catching technology takes the first place in license plate recognition of parking lot depending on its 99.58 /% recognition rate.

In addition, there is a big disadvantage of the electronic license plate, that is, it has only the "verification" function and no "monitoring" function. Because the RFID is adopted, the information about the vehicle can only be provided by the RFID electronic license plate label on the vehicle, while the video license plate recognition is to obtain the vehicle information by taking real-time photos. In other words, the electronic license plate is equivalent to the direct sensing "ID card", and the video license plate recognition is equivalent to looking at the face first and then pulling out the ID card. Although direct sensing is fast and convenient, it is far less secure and reliable than video license plate recognition.

Therefore, in the future, electronic license plate may become the main means of vehicle identification in the field of public transport depending on its convenience, but it still needs video license plate recognition as an important supplement.
