Embodiment Construction

[0057]In the related technology, the electronic device collects face images, and sends the collected face images to the server, and the server uses face recognition technology to calculate the similarity between the received face images and the pre-stored face images, Authenticate.

[0058] In the case of low light, the electronic device may have poor image quality of the collected face image due to the light problem of the current environment.

[0059] When the image quality of the face image collected by the electronic device is poor, for example, the image is blurred, the light of the image is dark, etc., the similarity calculated by the server is less than the set threshold, which leads to the failure of authentication of the legitimate user. Even if the server preprocesses the face image to obtain a clear face image. However, in the case that the face feature points used for face recognition are incomplete, it will still cause legitimate user authentication to fail.

Abstract

The invention discloses a face image acquisition method and device and electronic equipment, and the method comprises the steps: determining a face posture corresponding to at least one frame of preview image based on the face feature points of each frame of preview image in the at least one frame of preview image acquired by the electronic equipment; determining a first state of the electronic equipment when the electronic equipment collects a preview image, wherein the first state represents the stability of the electronic equipment; under the condition that the face posture corresponding tothe at least one frame of preview image meets a first set condition and the determined stability, represented by the first state, of the electronic equipment meets a second set condition, outputtinga first photo based on the at least one frame of preview image, wherein the first photo is used for the server to carry out identity authentication.

Description

technical field [0001] The invention relates to the technical field of Fintech face recognition technology, in particular to a method, device and electronic equipment for collecting face images. Background technique [0002] In related technologies, in application scenarios involving account fund security or information security involving financial services, face recognition technology is used to determine the identity of the user by calculating the similarity between the currently collected face image and the pre-stored face image. authenticating. However, under the condition that the image quality of the currently collected face image is poor, it will result in failure of authentication of the legitimate user. Contents of the invention [0003] In view of this, the embodiment of the present invention expects to provide a method, device and electronic device for collecting face images, so as to solve the technical problem in the related art that authentication of legitim...
