Claim 5:
6. The method according to claim 2, wherein a training process of the face mask recognition model comprises:
establishing an initial face mask recognition model;
acquiring positive and negative image samples and annotation results of the positive and negative image samples, wherein human faces comprised in the positive image samples wear face masks and human faces comprised in the negative image samples do not wear face masks, and the annotation results comprise labels for indicating whether the human faces in the image samples wear the face masks and position information of the face masks;
training the initial face mask recognition model by using the positive and negative image samples as inputs of the face mask recognition model and the annotation results of the positive and negative image samples as outputs of the face mask recognition model, to obtain the face mask recognition model.
