Embodiment Construction

[0053] 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.

[0054] The purpose of fingerprint registration is to save the fingerprint, so that the fingerprint image collected during identification can be compared with the registered fingerprint image during identity recognition. The fingerprint registration method provided by each of the following embodiments of the present invention is to collect multiple fingerprint images for each user to be registered, and use the feature values ​​of the pixels in the fingerprint im...

Abstract

The present application provides a fingerprint registration method and device. Multiple fingerprint images are obtained, multiple non-boundary pixel points in each fingerprint image are determined as target pixel points, and the pixel feature values ​​of each target pixel point are calculated respectively. The pixel feature value has translation invariance and rotation invariance. According to the pixel feature value of the target pixel point, the fingerprint image to be stitched is determined in multiple fingerprint images, and then the fingerprint image to be stitched is stitched into a single complete fingerprint image, and the fingerprint image is saved. Single fingerprint image to complete fingerprint registration. Compared with the prior art that uses fingerprint minutiae features for registration, the present invention uses image pixels, that is to say, for fingerprints whose fingerprint lines are damaged but images can still be collected, fingerprint registration can be realized. At the same time, the multiple fingerprint images acquired can be smaller than the single image acquired in the prior art, so that the embodiment of the present invention can be well applied to various small-sized fingerprint sensors, therefore, the present invention has wider applicability.

Description

technical field [0001] The present application relates to the technical field of fingerprint authentication, in particular to a fingerprint registration method and device. Background technique [0002] In today's information society, it is necessary to identify and authenticate people's identities on various occasions. Traditional identity authentication methods such as password authentication are easy to be forged or lost. Therefore, it is more common to use biometric data such as fingerprints for identity identification. Specifically, the fingerprint information is pre-registered first, and when identification is required, the extracted fingerprint information is matched with the registered fingerprint information to obtain the identification result. [0003] The current fingerprint registration method uses a fingerprint sensor to collect a single fingerprint image, extracts the fingerprint lines in the fingerprint image, judges whether the fingerprint image can be regist...
