Abstract
The invention discloses a directly-photographed fingerprint acquisition method which is characterized by comprising the following steps: (1), setting a fingerprint acquisition module which comprises a housing cover, a photographing module and a light filling module, wherein the housing cover is a transparent or semitransparent component for carrying a finger, the photographing module corresponds to the housing cover to photograph a fingerprint on the housing cover and the light filling module is used for filling light for a shooting environment; (2), pressing the finger on the housing cover, filling light by the light filling module, and the photographing module directly photographs a fingerprint image. The invention also discloses a directly-photographed fingerprint acquisition construction used for implementing the method. The method and the construction have the advantages of small size, low cost, excellent operation experience and the like. The implement method is innovated, the photographing module is used for directly photographing the fingerprint so as to acquire the fingerprint, and the light filling module is matched with the photographing module to photograph for more than sixty times within one second in a state of white light and blue light conversion, so that finger acquisition errors are reduced and fake fingerprints are avoided. Moreover, the construction is simple and the product modality can be changed at will.
