Mask wearing condition monitoring method based on face and posture recognition

Abstract

The invention discloses a mask wearing condition monitoring method based on face and posture recognition. The mask wearing condition monitoring method comprises the following steps of: step 1, acquiring a monitoring video; step 2, performing face detection on an image in the video data, and detecting whether a face exists in the image or not; step 3, if a face exists in the image, identifying theface and performing identity authentication, determining a target identity corresponding to the face, and if all target identities cannot be determined, returning to the step 1; step 4, performing mask detection on a detected face region, and detecting whether the target wears a mask or not and whether the target wears the mask correctly or not; step 5, if the target does not wear the mask or doesnot wear the mask correctly, transmitting a prompt to the target; and step 6, performing posture detection on the target, if a hand touches mouth and nose regions, sending a prompt to the target, andotherwise, continuing the posture detection. According to the mask wearing condition monitoring method, the condition of mask wearing can be automatically monitored and reminded, and the bad habit ofwearing the mask can be corrected.

Description

technical field [0001] The invention relates to the fields of image processing and target detection, in particular to a method for monitoring mask wearing conditions based on face and gesture recognition. Background technique [0002] A mask is a common sanitary protective product. It can filter the air entering the nose and mouth by simply wearing it. It has a significant effect on blocking dust, droplets, harmful gases, etc. It is mostly used in factories, construction sites, hospitals, etc. Where filtering is performed. For the prevalence of infectious diseases, wearing a mask is a good way to block the spread of infectious diseases through droplets, and it needs to be worn by all staff. However, due to some reasons, some people do not wear masks or do not wear masks correctly, and they have wrong behaviors after wearing masks, so that the protective effect of masks has not been effectively exerted. In response to these situations, we need to properly remind these perso...

However, due to some reasons, some people do not wear masks or do not wear masks correctly, and they have wrong behaviors after wearing masks, so that the protective effect of masks has not been effectively exerted.

In response to these situations, we need to properly remind these personnel, and manual inspection and reminders will consume human resources and increase the risk of infection, so a method that can automatically identify and guide personnel to wear masks is needed
