Document Type and Number:
WIPO Patent Application WO/2022/110492
Kind Code:
A1
Abstract:
The present application relates to a finger vein-based identity identification method and apparatus, a computer device, and a storage medium. Said method comprises: acquiring branch information and bifurcation point information in vein skeleton diagrams corresponding to two finger vein images to be matched; respectively performing matching on the branch information and the bifurcation point information of the two vein skeleton diagrams to obtain multiple groups of matched bifurcation point pairs; acquiring coordinate offset amounts of each group of matched bifurcation point pairs, and obtaining multiple groups of target bifurcation point pairs by screening the groups of matched bifurcation point pairs according to the coordinate offset amounts; acquiring a similarity of each group of target bifurcation point pairs, and acquiring branch lengths of all branches in the vein skeleton diagrams; and according to the similarity of each group of target bifurcation point pairs and the branch lengths of all branches in the vein skeleton diagrams, obtaining a similarity of the two finger vein images, and performing identity identification according to the similarity. The accuracy of a result of calculation of a similarity of two finger vein images can be improved by using said method.
