Diagnostic method and system for identifying mouth breathing of children by using artificial intelligence

The invention discloses a diagnosis method and system for recognizing mouth breathing of a child by using artificial intelligence, and belongs to the technical field of remote intelligent diagnosis, and the method comprises the steps: collecting a face real-time video stream in the sleeping process of the child based on a set timestamp, and transmitting the face real-time video stream to a server side; face recognition is conducted on the face real-time video stream through the server side by means of a face detector, the relative relation alpha between the mouth opening amplitude and the overall lip width is obtained, and the relative relation alpha is used for representing the proportional relation between the mouth opening amplitude and the overall lip width; performing Kalman filtering processing on the relative relation alpha to obtain a continuous change condition of the processed relative relation alpha in the video stream; according to the continuous change condition, the mouth breathing of the child
