Intelligent identification method and device for baby sleep position

The invention discloses an intelligent identification method and device for a baby sleep position. A video analysis and mode identification method is adopted to identify the baby sleep position so as to timely discover important baby events like a baby kicks out a quilt, the face of the baby is covered by clothes, or the baby sleeps on the stomach. The method consists of three parts, namely sample feature modeling, real-time feature analysis and alarm judgment. In the sample feature modeling, textural features and SIFT (Scale Invariant Feature Transform) features of a sample image are analyzed, a sample feature template base is generated by means of feature fusion, furthermore, the features of a set monitoring area are analyzed while the real-time features are analyzed, the sleep position is identified in combination with the sample feature template base, the alarm type is judged, and then the alarm information is output. Due to the intelligent identification method and device, a guardian does not have to monitor the baby all the time by videos or observation on site, especially when the guardian sleeps soundly at night, the important baby events can be effectively and intelligently detected, identified and warned early and timely.
