How Is License Plate Recognition Good- TigerWong

How is License Plate Recognition good? License plate recognition technology has been applied in the security industry for a long time, and the technology is relatively mature. The application of artificial intelligence improves the accuracy of license plate recognition. For the manufacturers of license plate recognition algorithm, how to extend the recognition range of target vehicles and achieve more accurate recognition is what the market needs. So how to choose a good license plate recognition system has become the primary task. So what are the technical standards to evaluate the quality of a license plate recognition system? The first is the recognition rate of the license plate recognition system. Whether a license plate recognition system is practical or not, the most important index is the recognition rate. The international transportation technology department has made a special discussion on the recognition rate index, which requires that the correct recognition rate of all signs is 85% 95% 24 hours a day. In order to test the recognition rate of a license plate recognition system, the system needs to be installed in a practical application environment, run for more than 24 hours all day, collect the license plates of at least 1000 vehicles passing in natural traffic flow for recognition, and store the license plate image and recognition results for retrieval and viewing. Then, we also need to get the actual passing vehicle image and the correct manual recognition results. Secondly, the recognition speed of license plate recognition system is also key. The recognition speed determines whether a license plate recognition system can meet the requirements of real-time practical application. If a system with high recognition rate needs a few seconds or even minutes to recognize the results, the system will be of no practical significance because it can not meet the real-time requirements in practical applications. For example, in highway toll collection, one of the functions of license plate recognition application is to reduce traffic time, and speed is a powerful guarantee to reduce traffic time and avoid lane traffic jam in this kind of application. The recognition speed proposed by international transportation technology is less than 1 second, the faster the better. Finally, the background management of license plate recognition system. The background management system of a license plate recognition system determines whether the license plate recognition system is easy to use. It must be clearly recognized that it is impossible for the recognition rate to reach 100%. The damage, blur and occlusion of the license plate and the weather may affect the license plate recognition. What needs to be done is to pre analyze the "problem license plate" as much as possible to achieve the license plate recognition accuracy as much as possible.
