Vehicle re-identification method and device, storage medium and electronic equipment

The invention provides a vehicle re-identification method and device, a storage medium and electronic equipment, and relates to the technical field of image processing. The vehicle re-identification method comprises the following steps: acquiring an image of a to-be-identified vehicle; acquiring sub-images and key point features of the to-be-identified vehicle based on a first neural network, and forming an image feature group; inputting the image feature group into a second neural network, wherein the second neural network extracts global features of the to-be-identified vehicle; splicing and fusing the global features and the corresponding key point features to obtain a fused feature map; and based on the matching operation of the fused feature map and a feature warehouse, determining an identified vehicle. The key point features obtained based on the original image are richer and more fidelity in information, feature loss caused by zooming is reduced, the key point features and global features are fused, a
