Abstract

The application discloses a face recognition method and belongs to the technical field of face recognition, thereby improving the accuracy and reliability of face recognition. The method comprises thefollowing steps: acquiring a two-dimensional face image and a three-dimensional face image which are synchronously acquired by different image acquisition devices for a target face; determining the pixel position of each preset face key point in the two-dimensional face image and the content information of the two-dimensional image, and determining three-dimensional space coordinates of each preset face key point in the three-dimensional face image; constructing corresponding nodes according to the preset face key points, representing the adjacency relation of the nodes corresponding to the adjacent preset face key points in the preset face key points through undirected edges, and constructing an undirected graph; and through a pre-trained graph convolutional neural network, on the basisof the node feature matrix of the undirected graph, the preset adjacency matrix and the unit matrix of the preset adjacency matrix, carrying out graph feature extraction to obtain face features, and carrying out face recognition on the target face according to the extracted face features.

Description

technical field [0001] The present application relates to the technical field of face recognition, in particular to a face recognition method, device, electronic equipment and computer-readable storage medium. Background technique [0002] Face recognition is widely used in attendance, access control, security and other fields. In order to improve the recognition degree of face recognition for living human faces and improve the reliability of face recognition, in the prior art, the depth image of the face collected by the depth image acquisition device is often combined with the plane image of the face collected by the visible light image acquisition device Comprehensive face recognition. For example, in combination with the face key point information in the face plane image, determine the face key point in the face depth image, and then perform face liveness detection according to the depth information of the face key point in the face depth image. When it is confirmed th...
