Title:
PALM VEIN RECOGNITION METHOD AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/075601
Kind Code:
A1
Abstract:
A palm vein recognition method and device, being used for extracting a certain number of features from each part of a region of interest of a palm, improving the recognition rate of the palm vein. The method of the embodiments of the present application comprises: acquiring a target palm vein image of a user (101); extracting, from the target palm vein image, an image of a region of interest (ROI) (102); dividing the image of the ROI into at least two sub-regions (103); using a preset algorithm to extract target feature points from each of the sub-regions (104); performing feature comparison on the extracted target feature points and preset feature points, so as to obtain matching point pairs (105); determining whether each pair of the matching point pairs is a true match (106); if it is a true match, retaining the matching point pair (107); if it is a false match, removing the matching point pair (108).
