The invention discloses a child
mouth breathing monitoring method, device and equipment and a medium, and the method comprises the steps that a non-
contact sensor group is used for synchronously collecting multi-mode physiological data of a target child in the
sleep period, and the multi-mode physiological data at least comprises a face thermal imaging video
stream, a thoracic and abdominal micro-motion
signal and an environment
audio signal; the multi-
modal physiological data is processed, multi-
modal features related to
respiration are extracted respectively, and the multi-
modal features comprise thermodynamic change features of mouth and
nose areas extracted based on a face thermal imaging video
stream,
respiratory effort waveforms extracted based on thoracic and abdominal micro-motion signals, and the
respiratory effort waveforms extracted based on the thoracic and abdominal micro-motion signals; extracting a sound source spatial position and a spectrum feature of
breathing sound based on the environment
audio signal; inputting the multi-modal features into a pre-trained
mouth breathing recognition model, and outputting a judgment result of the functional
mouth breathing event of the target child within a
specific time period; and generating a mouth
breathing monitoring report of the target child based on the judgment result.
