Problems solved by technology

[0002] Smart terminals can use passwords for security protection. For example, passwords can be entered in smart phones for verification, but based on passwords, users need to memorize and input them, which is cumbersome. In related technologies, biometric technology has begun to be applied to smart terminals, such as face recognition. and fingerprint recognition

Embodiment Construction

[0022] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatuses and methods consistent with aspects of the present disclosure as recited in the appended claims.

[0023] Embodiments of the present disclosure provide a palmprint recognition method that can be applied to a smart terminal, forming another recognition approach different from common fingerprint recognition methods. The smart terminal includes, for example, a smart phone, a tablet computer, etc., and these terminals usually have a camera capable of capturing images.

Abstract

The invention provides an SIFT (Scale Invariant Feature Transform) palmprint recognition method and device, and an intelligent terminal. The method comprises the following steps: acquiring a palmprint image to be verified by using a camera of the intelligent terminal; acquiring first SIFT feature points in the palmprint image to be verified, carrying out matching verification on the first SIFT feature points and second SIFT feature points in a registered palmprint image, and determining that the palmprint image to be verified passes the verification when the palmprint image to be verified is matched with the registered palmprint image. Due to the adoption of the scheme, the recognition process is simpler and more convenient.

Description

technical field [0001] The present disclosure relates to an intelligent terminal, in particular to a SIFT-based palmprint recognition method and device, and an intelligent terminal. Background technique [0002] Smart terminals can use passwords for security protection. For example, passwords can be entered in smart phones for verification, but based on passwords, users need to memorize and input them, which is cumbersome. In related technologies, biometric technology has begun to be applied to smart terminals, such as face recognition. and fingerprint recognition. Contents of the invention [0003] In order to overcome the problems existing in related technologies, the present disclosure provides a SIFT-based palmprint recognition method and device applied to smart terminals, and smart terminals, so as to make the recognition process simpler and more convenient. [0004] According to a first aspect of an embodiment of the present disclosure, a SIFT-based palmprint recogn...
