The invention discloses a license plate positioning and recognizing method based on multi-feature fusion. The method comprises extracting the color difference features and the edge features of a license plate image and the texture projection features of license plate characters; fusing the edge features of the license plate image with the texture projection features of the license plate characters, carrying out mathematical morphology operation to coarsely position the license plate; fusing the color difference features of the license plate image by using the license plate coarse positioning image to finely position the license plate and determine a complete license plate area; normalizing the license plate characters in the license plate area; training samples to obtain a trained network,training four sub-networks by using four samples including Chinese characters, letters, letters and numbers, and numbers in order to obtain the corresponding number of nodes and weights, extracting the positioned license plate image features one by one, reading the corresponding number of nodes and the weights, recognizing the normalized license plate characters in respective networks, and outputting a recognition result. The method can improve the accuracy of license plate recognition.
