Effective automatic comparison query technology, the recognized license plate number should be automatically compared with thousands of license plate numbers in the database and prompt an alarm.
License plate recognition rate
Whether a license plate recognition system is practical or not, the most important index is recognition rate. International traffic technology has made a special discussion on the recognition rate index, requiring all cards to have a correct recognition rate of more than 95% in 24 hours. In order to test the recognition rate of a license plate recognition system, it is necessary to install the system in a practical application environment, run for more than 24 hours all day, collect at least 1000 license plates during natural traffic flow, and store license plate images and recognition results for easy retrieval.
Then, we need to get the actual images of passing vehicles and the correct artificial recognition results. If it takes several seconds or even minutes for a system with high recognition rate to recognize the result, then the system has no practical significance, because it can't meet the real-time requirements in practical applications.
