Embodiment 1

[0038] Such as figure 1 As shown, the embodiment of the present invention provides a method for collecting fingerprints by rolling and print fusion of living body collection, including the following steps:

[0039] A1, collect the fingerprints presented when the finger is placed flat on the collection panel;

[0040] A2, collect the fingerprints presented during the process of turning the finger from the flat position to the left until the left edge of the finger touches the collection panel;

[0041] A3, collect the fingerprints presented during the process of turning the finger from the position where the left edge touches the collection panel to the right until it is placed flat on the collection panel;

[0042] A4, collect the fingerprints presented during the process of turning the finger from the flat position to the right until the right edge of the finger touches the collection panel;

[0043] A5, collect the fingerprint presented during the process of turning the fi...

Abstract

The invention discloses a living body acquisition rolling and flat printing fusion acquisition fingerprint method and relates to the fingerprint identification technology field. In the method, fingerprints of different positions of fingers are collected in steps and finally a complete finger fingerprint is acquired. During an acquisition process, for a person whose fingerprints need to be collected, a difficulty of rolling the fingers is reduced, handleability of fingerprint acquisition is increased, and a problem that collected fingerprint quality can not be guaranteed because finger edges are not sufficient, a force is not uniform, rotation is not coherent and so on is solved. The collected fingerprint quality is greatly increased. In addition, during one acquisition, a flat printing fingerprint and / or a rolling fingerprint can be acquired simultaneously. In the prior art, the flat printing fingerprint and the rolling fingerprint need to be collected for two times. Therefore, in the invention, an acquisition frequency of the flat printing fingerprint and the rolling fingerprint is reduced by half.

Description

technical field [0001] The invention relates to the technical field of fingerprint identification, in particular to a method for collecting fingerprints by combining scrolling and printing in living body collection. Background technique [0002] Before the 1980s, the collection of printed fingerprints was mainly based on the traditional artificial ink printing method. Therefore, the fingerprint rolling process is limited by the shape of the ink, and the fingerprint collection can only be completed once by rolling. At the same time, during the rolling process, it cannot be moved. , pause, repeat or go backwards, and turn your fingers from left to right or vice versa to leave fingerprints. [0003] With the development of computer technology, live fingerprint electronic collection equipment gradually appears. Because it is not limited by ink printing, it can realize the optimal repeated collection of the same finger under the premise of ensuring quality, simple collection, no ...
