An image matching method includes: performing feature extraction processing on a first image to obtain K first feature maps; performing feature extraction processing on a second image to obtain K second feature maps; determining a first feature vector of each of M first feature points in the first image based on the K first feature maps, to obtain M first feature vectors; determining a second feature vector of each of N second feature points in the second image based on the K second feature maps, to obtain N second feature vectors; determining a quantity of feature point pairs based on the M first feature vectors and the N second feature vectors; and determining an image matching result based on the quantity of feature point pairs.
