Non-contact oral respiration detection device and method and storage medium

Abstract

The invention discloses a non-contact oral respiration detection device and method and a storage medium. The method comprises the steps of adopting a thermal imager module for collecting the temperatures of different positions of a face of a to-be-detected target in a non-contact mode and generating an infrared thermogram sequence; receiving the pulse signal of a processor by using a steering engine module, and adjusting the acquisition direction of the thermal imager module; enabling the processor to receive the infrared thermogram sequence of the thermal imager module and position the position of the human face in the infrared thermogram, adjusting the acquisition direction of the thermal imager module to enable the human face to be detected to be located in the detection area, and positioning two interested areas of the nostrils and the mouth from the infrared thermogram of the human face; and according to the extracted temperature data time sequences of the nostrils and the mouth,judging whether the to-be-detected target performs mouth breathing and the mouth breathing intensity or not, and generating a breathing report. According to the method, whether the to-be-detected target is in mouth breathing or nose breathing can be distinguished, the breathing report of the to-be-detected target during sleep can be generated, and the sleep of a user is not influenced.

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
