A non-contact mouth breathing detection device, method and storage medium

Abstract

The invention discloses a non-contact mouth breathing detection device, method and storage medium, comprising: using a thermal imager module to non-contactly collect the temperature of different positions of the face of the target to be measured and generating a sequence of infrared thermal images; using a steering gear The module receives the pulse signal from the processor, and adjusts the acquisition direction of the thermal imager module; the processor receives the infrared thermal image sequence of the thermal imager module and locates the position of the face in the infrared thermal image, and adjusts the thermal imager module. The acquisition direction makes the face to be tested be located in the detection area, locate the nostril and mouth two regions of interest from the infrared thermal image of the face, and judge whether the target to be tested is Perform mouth breathing and mouth breathing intensity, and generate a breathing report. The invention can distinguish whether the target to be tested is mouth breathing or nasal breathing, can generate a breathing report of the target to be tested during sleep, and will not affect the user's sleep.

Description

technical field [0001] The present invention relates to the technical field of mouth breath detection, in particular to a non-contact mouth breath detection device, method and storage medium. Background technique [0002] Mouth breathing is a bad breathing habit. Long-term mouth breathing will affect the normal development of dento-maxillofacial, form adenoid face, cause sleep apnea disorder, language barrier, and affect health. It is very important to detect and block mouth breathing in time, and the best time for treatment is when children are 3-5 years old. [0003] Most of the existing mouth breathing detection devices are contact type and non-intelligent physical devices. Mouth-breathing symptoms occur more often than during sleep, or can increase the weight of during sleep. The contact detection device will affect sleep, cause discomfort to the user, and cannot accurately reflect the breathing situation during daily sleep. Moreover, non-intelligent detection equipme...

AI Technical Summary

Problems solved by technology

Contact detection devices will affect sleep, cause discomfort to users, and cannot accurately reflect the breathing conditions during daily sleep

Moreover, non-intelligent detection equipment needs to rely on manual records, which adds extra workload to users

[0004] The invention patent with the publication number CN102499664B discloses a non-contact vital sign detection method based on video images. The detection method of the invention is realized by detecting the movement of the chest cavity. This method cannot distinguish whether the target to be measured is the mouth breathing or nasal breathing
