Is the Recognition Rate in the License Plate Recognition System the Standard That Determines the Qua

With the increasing number of vehicles and the increase of urban pressure, people pay more and more attention to the problem of difficult urban parking. Although the application of license plate recognition technology has helped reduce the pressure of urban traffic, with the acceleration of China's urbanization process, the traffic pressure will become more and more severe. Intelligent license plate recognition system has become an important equipment to alleviate the traffic pressure. As an important core equipment in intelligent traffic management system, license plate recognition system has been favored by various industries. However, for the more popular license plate recognition system, how to judge its quality from its appearance and performance? We know that the license plate recognition rate is a problem that people are more concerned about when purchasing the license plate recognition system, but can we judge the performance of the license plate recognition system only from the license plate recognition rate? The answer must be No. Firstly, the recognition rate of the license plate recognition system is not completely determined by its own factors, but also has a great relationship with the external environment. For example, lighting conditions, license plate damage or unlicensed vehicles are the main factors of the direct license plate recognition rate. Therefore, these external conditions are not determined by the quality and performance of the equipment. The recognition speed in the license plate recognition system also determines whether a license plate recognition system can meet the requirements of real-time practical application. For a set of license plate recognition system with relatively stable performance, its recognition speed only takes a few seconds. On the contrary, the recognition time of the parking lot system with unstable quality may take a few minutes to recognize the results, Therefore, there is a sense of violation with the fast traffic advantage of the license plate recognition system itself, so the recognition speed is a powerful guarantee for the license plate recognition system to be used in the parking lot. The background management function of license plate recognition system also determines its performance. The recognition results and vehicle image data are reliably stored. When the network system fails, the image data will not be lost, and it is convenient for manual troubleshooting afterwards; Effective automatic comparison and query technology, the recognized license plate number shall be automatically compared with the license plate number in the database and prompted for alarm, so as to obtain the relatively best comparison result. Therefore, the powerful function of the license plate recognition system determines its scope of use, and its performance determines whether the license plate recognition system can be recognized by more users. For the parking lot system manufacturers, only excellent technology can occupy the market.
