Problems solved by technology

[0005] The present disclosure provides a detection method for a target object wearing a mask and a thermal infrared image processor, to at least solve the problem in the prior art of detecting whether a target object wears a mask manually or based on a visible light image. The detection method requires a lot of human resources and the method of detecting whether the target object wears a mask based on visible light images is easily affected by the light intensity, resulting in low detection efficiency and low accuracy of the target object wearing a mask, which is likely to cause missed detection, false detection and Technical problems with false detection

Abstract

The invention discloses a method for detecting the mask wearing condition of a target object and a thermal infrared image processor. The method comprises the following steps: acquiring a first image acquired by thermal infrared image acquisition equipment; determining a first face image area containing the face of the target object in the first image; determining upper face temperature informationand lower face temperature information of the target object according to the image information of the upper image area and the lower image area of the first face image area; and determining whether the target object wears the mask or not according to the upper face temperature information and the lower face temperature information.

Description

technical field [0001] The present application relates to the technical field of mask detection, in particular to a detection method for a target object wearing a mask and a thermal infrared image processor. Background technique [0002] A mask is a commonly used sanitary product, which can effectively prevent dust, harmful gases, saliva droplets, etc. from entering and exiting the nose. In public places such as offices, shopping malls, and hospitals, wearing a mask can not only ensure that you are not harmed by the epidemic of infectious diseases, but also effectively prevent the spread of the virus; in areas with large dust in the working environment such as construction sites and factories, wear a mask It can prevent oneself from inhaling dust and causing harm to one's own health. In addition, in some key monitoring places, such as ATM cash machines, suspicious elements will deliberately cover their faces with masks in order to avoid being captured by cameras. Therefore...
