A face recognition method, a feature extraction model training method and a device thereof. Feature information of a video stream composed of a plurality of face images of the same person is processed through predetermined three-dimensional convolutional neural networks to obtain corresponding feature vectors, and face recognition is performed on the basis of feature vectors of faces in a database, so that optical flow information and spatial variation information can be added in the face recognition process, and the accuracy and generalization ability of face recognition are improved.
