Embodiment Construction
[0027] like figure 1 and Image 6 As shown, it is a method for recognizing license plate characters based on the neural network of data enhancement and data generation involved in this embodiment. Shadows caused by low light, overexposure, rain and sand and other factors. The shooting angle affects the deformation of the license plate. Shooting from the side or looking down will cause a relatively large degree of deformation of the characters. The real-time requirement means that the recognition speed of the license plate is very high. It is necessary to quickly recognize the characters of the license plate at the entrance of the ramp without causing road congestion.
[0028] The data enhancement and data generation method proposed in this embodiment only requires a small amount of manual marking of real license plates. The recurrent adversarial generation network requires a thousand or more real data, but these real data do not require manual annotation, because the traini...
