Non-contact rapid hand multimodal information fusion identification method

The invention provides a non-contact rapid hand multimodal information fusion identification method, which is characterized by comprising the following steps of: (1) acquiring hand images; (2) positioning key characteristic points of hand shapes; (3) extracting eigenvectors of the hand shapes; (4) positioning a palmprint ROI (region of interest) region and extracting eigenvectors; (5) setting a threshold value and carrying out primary matching of characteristics of the hand shapes to obtain alternative people; and (6) carrying out primary matching on palmprint images of the alternative peopleby a palmprint identification method to provide final judgment. The invention provides the personal identity identification method on the basis of multimodal biological characteristics of the hand shapes and palmprints, which is convenient and rapid to use, has no damage to a human body, cannot spread diseases, has high identification speed and can improve the identification rate and the stability of a system.
