Problems solved by technology

Since face recognition is sensitive to the pose and lighting conditions of face image acquisition, this face recognition method in the prior art will affect the human face when the face pose or ambient light in the registration link and recognition link changes. Accuracy of face recognition
[0003] It can be seen that the face recognition method in the prior art still needs to be improved

Embodiment 1

[0025] A face recognition method disclosed in the embodiment of the present application, such as figure 1 As shown, the method includes: Step 110 to Step 130.

[0026] Step 110, determine the posture features, ambient lighting features and face features of the face image to be recognized.

[0027] In the process of face recognition, it is first necessary to obtain at least one face image of the face to be recognized, and input the image of the face to be recognized to a preset face recognition engine for recognition. In the embodiment of the present application, there is no limitation on the specific manner of acquiring the image of the face to be identified, and no limitation on the lighting environment for acquiring the image of the face to be identified.

[0028] In some embodiments of the present application, the posture feature refers to the posture of the human face represented by any one or more angles of the pitch angle, left-right rotation angle, and left-right sway ...

Embodiment 2

[0059] A face recognition device disclosed in the embodiment of the application, such as image 3 As shown, the device includes:

[0060] A feature determination module 310, configured to determine gesture features, ambient lighting features, and face features of the face image to be recognized;

[0061] A face feature set forming module 320, configured to select at least one face feature consistent with the posture feature and ambient light feature of the face image to be recognized from the preset face feature library to form a face feature set;

[0062] The face recognition module 330 is configured to compare the face features of the face image to be recognized with each face feature in the face feature set, and obtain the face recognition of the face image to be recognized. result.

[0063] In some embodiments of the present application, such as Figure 4 As shown, the device also includes:

[0064] The weight updating module 340 is configured to update the weights use...

Abstract

The embodiment of the invention discloses a face recognition method, belongs to the technical field of visual recognition, and is helpful for improving the accuracy of face recognition. The face recognition method disclosed by the embodiment of the invention comprises: determining attitude features, ambient light features and face features of a to-be-recognized face image, screening out at least one face feature conforming to the attitude feature and the ambient light feature of the to-be-recognized face image from a preset face feature library to form a face feature set, and comparing the face features of the to-be-recognized face image with the face features in the face feature set to obtain a face recognition result of the to-be-recognized face image. According to the method, a registered face image which is the same as or similar to a to-be-recognized face image in posture and ambient light conditions is selected for comparison, the influence of different postures and ambient lighton face comparison can be reduced, and complex ambient light changes and posture changes can be dealt with, so that the face recognition accuracy of an actual scene is improved.

Description

technical field [0001] The embodiments of the present application relate to the technical field of visual recognition, and in particular, to a face recognition method, device, electronic equipment, and computer-readable storage medium. Background technique [0002] Face recognition is widely used in practical scenarios such as time attendance, payment, meeting sign-in, and entering parks or scenic spots by swiping your face. The face recognition method in the prior art is as follows: firstly, the user to be recognized needs to register one or more face images and store them in the face database; Compare the face images in the image to complete face recognition. Since face recognition is sensitive to the pose and lighting conditions of face image acquisition, this face recognition method in the prior art will affect the human face when the face pose or ambient light in the registration link and recognition link changes. Accuracy of face recognition. [0003] It can be seen...
