Infant behavior state detection method based on target detection

The invention discloses an infant behavior state detection method based on target detection. According to the invention, the monitoring process mainly comprises the following steps: firstly, performing function selection on whether an infant sleeps or not so as to determine a specific monitoring task, and if the infant selects to sleep, selecting a judgment basis for kicking a quilt; the obtained RGB video frame is preprocessed; then, inputting the preprocessed picture into a YOLOX-tiny target detection algorithm based on structure simplification and feature enhancement improvement, so as to obtain an infant positioning and behavior state classification preliminary result; then, data storage is carried out, and detection data is processed and analyzed based on a mode filter thought; and finally, outputting infant behavior state detection results under different function selection conditions, and giving an alarm in time when the infant climbs, kicks a quilt and is lost. The method is of great significance in r
