Image matching method, device, computer device and storage medium

The invention relates to the field of computer technology, and provides an image matching method, a device, a computer device and a storage medium. The image matching method comprises the following steps: a finger vein image to be detected is obtained and grayscale processing is performed to obtain a grayscale image; a fast algorithm is used to extract the feature points of finger vein veins in gray-scale images; a sift algorithm is used to process the feature points, and the eigenvectors of each feature point are obtained; for each feature point, the cosine value between the feature vector ofthe feature point and the feature vector of each legal feature point in the legal image is calculated; if the cosine value is less than the preset cosine threshold value, the feature point of the cosine value is confirmed as the matching point; and if the cosine value is less than the preset cosine threshold value, the feature point is confirmed as the matching point; if the number of matching points is greater than the preset threshold value, it is confirmed that the finger vein image to be detected matches the legal image. The technical proposal of the invention realizes the accurate identification and matching of finger vein patterns, thereby effectively improving the accuracy of finger vein pattern matching.
