Nowadays, license plate recognition cameras are widely used in intelligent traffic management systems and have played a huge role in vehicle management. As we all know, the license plate recognition (LPR) system is an intelligent recognition system based on image processing, pattern recognition, and other technologies. The camera takes pictures of vehicles driving on the road, forms an image, and then recognizes the license plate number.
Technical Support
License plate recognition has been successfully applied in various industries such as intelligent transportation systems, entrance and exit management systems, public security image frame systems, and mobile police systems. The algorithm combines license plate positioning, license plate character segmentation, license plate character recognition and other algorithms, so that the system has the advantages of high recognition efficiency, fast speed, strong adaptability, easy to use and so on. Widely praised.
