Face recognition method and device and storage medium

The invention discloses a face recognition method and device and a storage medium. The method comprises the steps of face extraction cutting: carrying out feature recognition on a face picture, determining a cutting boundary according to coordinates of face key feature points based on a preset cutting rule, and obtaining a cut picture comprising a face recognition area and an edge area surroundingthe face recognition area; recognition model training: obtaining identity identification information corresponding to the cut picture, and training a face recognition model through the cut picture and the identity identification information based on a deep convolutional neural network to obtain a face recognition feature vector; and face recognition: obtaining a to-be-recognized picture includingface information, obtaining a to-be-recognized feature vector according to the face recognition model, and comparing the to-be-recognized feature vector with the face recognition feature vector to obtain the corresponding ide
