Method for recognizing a license plate number using license plate number recognizer and license plate number recognition system implementing the same

摘要

As a method for a license plate recognition system to recognize a license plate number from a low-resolution image, it receives a low-resolution image and a high-resolution image photographed for one vehicle, and a high-resolution license plate image extracted from the high-resolution image, a high-resolution license plate image, a high-resolution license plate image, and a low-resolution image extracted from the low-resolution image. A license plate image and a low-resolution license plate number are generated as learning data. After training the neural network model using the learning data, the license plate number is extracted from the low-resolution image received from the information collection means. At this time, the learned neural network model includes a first neural network model trained to output a high-resolution license plate image when a low-resolution license plate image is input and a second neural network model trained to map a low-resolution license plate image to a high-resolution license plate image.
