Embodiment Construction

[0018] see figure 1 , the pen-hold fingerprint collection method provided in this embodiment includes the following steps:

[0019] 1) A fingerprint collection module is set, the fingerprint collection module includes a housing 1, a photographing module 2 and a supplementary light module 3, wherein the housing 1 is a transparent or translucent member that carries fingers, and the photographing module 2 and the housing Corresponding to the cover 1, the fingerprint on it is photographed, and the supplementary light module 3 supplements the light to the shooting environment;

[0020] 2) Press your finger on the housing 1, fill in the light through the supplementary light module 3, and the photographing module 2 directly captures the fingerprint image.

[0021] 3) Recognize the fingerprint images captured by the photographing module 2 to collect accurate fingerprints.

[0022] Specifically, in step 1), the housing 1 includes a pressure-sensitive element 4, which carries a finger...

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.

Description

technical field [0001] The invention relates to fingerprint shooting processing, in particular to a direct-shoot fingerprint collection method and its structure. Background technique [0002] With the development of science and technology, and due to the singleness of fingerprints, more and more fingerprint collection devices use fingerprint collection and identification to judge people's identity or directly replace passwords to avoid mistakes and ensure safety. The traditional fingerprint collection method is to collect fingerprints by linear scanning and capacitance potential difference, which have the problems of large volume, low efficiency and high cost respectively. Moreover, this method is very cumbersome and error-prone in subsequent identification processing, resulting in certain defects in its reliability. Contents of the invention [0003] The present invention aims at the deficiencies in the prior art, and provides a direct-type fingerprint collection method ...
