Problems solved by technology

[0004] However, the fingerprints of the same user will be different under different circumstances. For example, when the finger is wet or sweaty, the fingerprint image is blurred and difficult to identify, making it difficult to confirm the identity even if it is the fingerprint image of the same user. poor experience

Abstract

The present invention proposes a fingerprint recognition method, device and electronic equipment, wherein the method includes: collecting a first image before the user's finger touches the fingerprint recognition component; the second image of the fingerprint identification component; after the user's finger touches the fingerprint recognition component again and the user's finger leaves, a third image is collected; according to the first image, the second image and the third image, a fingerprint for fingerprint identification is generated Fourth image. Through the fingerprint identification method, device and electronic equipment provided by the present invention, the impurity images in the fingerprint image to be identified can be effectively removed during fingerprint identification, and only clear fingerprint images can be identified, thereby improving the accuracy of fingerprint identification , which improves the user experience.

Description

technical field [0001] The invention relates to the field of biological identification, in particular to a fingerprint identification method, device and electronic equipment. Background technique [0002] Everyone's fingerprint is unique, and almost unchanged for a lifetime. Based on the uniqueness and stability of fingerprints, fingerprint recognition technology is widely used in identity verification, and in fields such as time attendance, access control, information security, mobile terminals, and computer applications. has developed rapidly. [0003] The relevant technology mainly matches the fingerprint images of the same user for identification to confirm the identity, and compares the collected fingerprint images with the pre-stored fingerprint images to verify their identity. [0004] However, the fingerprints of the same user will be different under different circumstances. For example, when the finger is wet or sweaty, the fingerprint image is blurred and difficul...
