Abstract
Biometric measuring apparatus for recognizing a person's identity based on measurements performed on the person's hand. An arrangement for producing and storing a silhouette image of at least a portion of a person's hand is combined with an arrangement for producing and storing a structured light image of the same portion of a person's hand. An analyzing device analyzes the stored images to produce hand feature data. The silhouette image provides finger silhouette feature data and the structured light image provides finger height characteristic data. The apparatus stores hand feature data obtained during a hand enrollment operation cycle to compare with hand feature data produced in a subsequent hand bid operation cycle to determine if the person has previously been enrolled on the apparatus.
