Finger vein recognition method, device and equipment

The invention discloses a finger vein recognition method, and the method comprises the steps: obtaining a collected finger vein image, and extracting a target region image in the finger vein image; calculating a plurality of target curvature graphs corresponding to the target area image according to preset curvature calculation angle parameters and window scale hyper-parameters; inputting the target area image and the plurality of target curvature graphs into a first neural network model to extract a plurality of vein features; and performing feature fusion processing on the plurality of veinfeatures to obtain a target vein feature, and identifying the finger vein image according to the target vein feature and a pre-stored reference vein feature. Therefore, according to the invention, thetarget vein feature for identification is ensured to reflect the finger vein information in a richer and more detailed manner, a better finger vein identification effect is finally obtained, and theuser experience is improved
