Embodiment Construction

[0018] see figure 1 , the wrap-around 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 light to the shooting environment; The ring is set around the shooting module 2 and illuminates upwards, and the diffuser plate 5 is set above the fill light 6 to diffuse and homogenize the light;

[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 photogra...

Abstract

The invention discloses a surrounding type fingerprint acquisition method. The surrounding type fingerprint acquisition method is characterized by comprising the following steps: (1) setting a fingerprint acquisition module, wherein the fingerprint acquisition model comprises a housing, a shooting module and a light supplementing module, wherein the housing is a transparent or semitransparent component and is used for bearing a finger, and the shooting module corresponds to the housing and is used for shooting a fingerprint on the housing, the light supplementing module is used for supplementing light for a shooting environment, the light supplementing module comprises a light diffusion plate and a plurality of light supplementing lamps which are annularly arranged around the shooting module and radiate light upwards, and the light diffusion plate is arranged above the light supplementing lamps and is used for diffusing and homogenizing the light; (2) pressing the finger on the housing, supplementing light through the light supplementing module and directly shooting a fingerprint image through the shooting module. The invention also discloses a surrounding type fingerprint acquisition structure for implementing the method. According to the surrounding type fingerprint acquisition method, the fingerprint can be acquired by direct shooting, the structure is concise and the form can be freely changed. In addition, surrounding light supplementing is adopted, so that the fingerprint is more distinct and distortion is reduced.

Description

technical field [0001] The invention relates to fingerprint photographing processing, in particular to a surrounding 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 surrounding fingerprint collection met...
