Claim 7:
8. The system according to claim 6, wherein, the acquiring vehicle state data comprises acquiring vehicle information, the data acquisition module comprises:
image acquisition unit, used to obtain the vehicle image, and use the YOLOv5 vehicle detection algorithm to extract the license plate image;
image transformation unit, used to transform the license plate image into a positive-view license plate image; and
image recognition unit, used to recognize the positive-view license plate image by using the license plate recognition network,
wherein the image recognition unit recognizes the positive-view license plate image by using the license plate recognition network, comprises:
using the license plate recognition (LPRnet) wide convolutional neural network to extract features from the positive-view license plate image, to obtain contextual information of local characters; and
decoding the probability of the local characters, finding multiple most probable sequences through beam search, and returning the first sequence that best matches a predefined template set, which is the license plate recognition result.
