The invention provides a vehicle license plate Chinese character recognition method based on multi-feature fusion. The vehicle license plate Chinese character recognition method comprises the following steps: unifying images to be detected; improving HOG features to obtain Chinese character edge features of the to-be-detected images; obtaining Chinese character gray features of the to-be-detected images; obtaining Chinese character textural features of the images to be detected based on LBP feature theory; fusing the Chinese character edge features, the gray features and the textural features of the images to be detected to obtain fusion feature vectors of the to-be-detected images; forecasting a classification result based on an SVM classifier. The vehicle license plate Chinese character recognition method comprehensively uses global features and local features of the Chinese characters, can be used for identifying more accurately, and has high robustness on low-quality images and high-interference images.
