Embodiment Construction

[0058] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0059] In the prior art, the traditional fingerprint identification technology acquires the fingerprint image through light or capacitance technology, but some abrasive tools made according to the fingerprint can also capture the fingerprint image, which seriously affects the accuracy and security of the fingerprint identification technology, and the finger It is unavoidable to leave fingerprints after contact with other objects. Forging new fingerprints throug...

Abstract

The invention provides a fingerprint collection and recognition method and device. The method comprises the steps of collecting a first fingerprint picture when a first pressure value is applied to afinger and a second fingerprint picture when a second pressure value is applied to the finger; and according to a preset first fingerprint sample when the first pressure value is applied to the finger, a preset second fingerprint sample when a second pressure value is applied to the finger, the first fingerprint picture and the second fingerprint picture, carrying out fingerprint identification onthe fingerprint picture passing validity verification. According to the invention, the accuracy of the fingerprint identification technology and the accuracy of finger living body monitoring are improved, the deformation of the finger during pressing is considered, the situation that the finger cannot be successfully identified due to deformation is avoided, and the fingerprint left by the contact between the finger and other articles is prevented from being stolen.

Description

technical field [0001] The present application relates to the field of fingerprint identification, in particular, to a pressure-based fingerprint acquisition and identification method and device. Background technique [0002] In recent years, the application range and scenarios of biometric identification technology have become wider and wider, especially in recent years, the integration of fingerprint collection equipment with mobile devices and terminals has made fingerprint identification technology one of the most widely used and most accepted biometric identification technologies. one. Moreover, the characteristics of fingerprints that are invariable, unique and convenient for life make fingerprint recognition technology almost become synonymous with biometrics. [0003] Fingerprint image acquisition is the first step in fingerprint identification, and the quality of the acquired image directly affects the subsequent fingerprint image identification process. There are...
