  • Publication number: 20250139997
    Abstract: An edge-computing method and an edge-computing system for automatic license plate recognition are provided. The edge-computing method is performed in a terminal system of a vehicle. The edge-computing system includes a photographing module and a computing circuit. A streaming video is generated by the photographing module. An object-detection model is used to identify a license plate in each frame of the video and recognize characters from an image of the license plate. A confidence algorithm is used to calculate a confidence level of each of the characters and a confidence score of all of the characters. Confidence scores of the license plate in continuous frames within a period of time are calculated, and the frame having a highest confidence score is stored in a memory. Afterwards, a classification model is used to recognize features of vehicle, such as a vehicle jurisdiction, a color, a brand, and a model.
