three criteria for judging the quality of license plate recognition system < / a >

　　1. License plate recognition rate

In order to test the recognition rate of the license plate recognition system, when detecting the license plate recognition system, install it in the actual application environment, always work for more than 24 hours, collect at least 1000 information samples of natural traffic flow for license plate recognition, and store the recognition results and license plate images to obtain the view. Compare the correct vehicle information manually identified

　　2. License plate recognition speed

The speed of license plate recognition determines that the license plate recognition system can meet the real-time requirements of practical applications. The recognition rate of license plate recognition system is very high. The speed of judging the recognition rate is that if the recognition result cannot be obtained within a few seconds, the system has no practical significance. License plate recognition system is mainly responsible for reducing road traffic time, and speed is a powerful guarantee to reduce traffic time and avoid lane traffic congestion in this application

　　3. Platform management system

The storage of identification results and vehicle image statistics can maintain the image statistics without loss. When the system software operates, it is conducive to the manual service management method. At the same time, it can also check the management of the whole parking lot in real time and find problems in real time
