The development of license plate recognition technology

License plate recognition technology has been used for more than three years. The technology has also experienced several generations of development. So today, follow Ali's city to talk about the evolution of license plate technology.

Analog transmission, PC-side identification

* On behalf of the license plate recognition technology, the traditional analog camera video transmission to the control PC side, remote control PC side identification software to identify and extract the license plate information. This generation of product cameras does not have the ability to recognize itself, but it is also based on the traditional analog simulator, so the video is poor and the recognition rate is low. This is the reason why the recognition rate of previous license plate recognition systems was low.

Digital transmission, control board recognition

To the second generation license plate recognition system, a digital camera has been used, and the image acquisition has been greatly improved. In the case of higher image quality, the recognition rate has also been greatly improved. The identification end is moved from the PC-side software to the embedded board. The license plate recognition rate is usually above 99% through technology upgrade. However, due to the relatively high cost of expensive technology, license plate recognition is not universally available.

200W HD, camera embedded chip

Through 2 million high-definition cameras, embedded chip recognition, greatly improving the license plate recognition rate, the recognition rate and basically reached more than 99.7%. Through hardware integration, hardware cost and cost are greatly reduced. This is a basis for the universal popularity of license plate recognition systems. Today, third-generation vehicle license plate recognition systems are basically based on this architecture. The lower equipment cost, higher recognition rate, and the maturity of the license plate recognition system software make the license plate recognition system universal. Charges are still calculated by the local PC.

Local identification, cloud computing

Through the local high-definition camera for license plate recognition, the network license plate data to the cloud, through the cloud for storage and billing. This realizes the localization of the parking system to the local terminal, greatly improving the stability of the local system, refueling exports, license plate recognition camera to identify the factory vehicles, cloud background charging vehicle data, and directly from the cloud background to the payment platform to issue payment applications, that is, Our common Alipay payment and WeChat payment. The charging method is also charged by traditional cash, passive scanning, active scanning, and upgrading to non-incentive payment. Allows the owner to stay in the customer's experience without having to stay throughout the game.

The Ali City Smart Cloud Parking System is the fourth generation of license plate recognition technology. Combined with the non-inductive payment technology, WeChat's non-incentive payment, Alipay's non-incentive payment, and traditional payment methods. Create a variety of custom card voucher functions to extend the parking business to a new height.

The two major payment giants in order to promote the use of non-sentiment payment applications in the parking lot, Alipay launched an incentive policy of 500-50000 per car park, and WeChat also announced the list of incentive policies. There are 400 car parks in the country in an incentive policy. Each policy subsidy of 20,000 yuan is to be provided. The specific list can be linked to Ali City.
