An early warning method of infant suffocation or sudden death based on single-stage face positioning algorithm

Abstract

The invention relates to a method for early warning of infant suffocation or sudden death based on a single-stage face positioning algorithm, which belongs to the field of computer vision; it solves the current problems of preventing and alarming infant suffocation or sudden death through real-time images; its technical scheme is : Based on the Acc-Retinaface network model of the single-stage face positioning algorithm, it can predict the baby face frame, 68 face key points, and face key point occlusion information; monitor the baby face and surrounding conditions, and return the baby face image in real time. Calculate the risk value of sudden suffocation death of the current baby by the weight value of the key point of the baby's face being blocked; compare the risk value of sudden suffocation death with the set alarm threshold and risk threshold, and return the corresponding early warning signal to the terminal device. The invention recognizes the baby's face in real time and detects the occlusion of the face, and provides early warning of suffocation or sudden death of the infant, which can effectively reduce the probability of suffocation or sudden death of the infant caused by reasons such as mouth and nose occlusion, gastroesophageal reflux, and sudden infant death syndrome.

Description

technical field [0001] The invention relates to an infant suffocation or sudden death early warning method based on a single-stage face positioning algorithm, which belongs to the field of computer vision. Background technique [0002] Babies refer to children born in the period of 6 weeks to 12 months. Before the first year of age, the functions of various systems are immature, and the resistance to external dangers is extremely weak. Sleeping on the stomach, covering the mouth and nose, and sleeping with others can easily cause the baby to suffocate. At the same time, gastroesophageal reflux (spitting up milk) caused by the infant's immature digestive function is also an important factor leading to the occurrence of infant asphyxia. According to statistics on the causes of accidental death in children, the death rate caused by accidental suffocation of infants is extremely high. [0003] Sudden Infant Death Syndrome (hereinafter referred to as SIDS) is also one of the im...

AI Technical Summary

Problems solved by technology

[0006] Generally speaking, the current technology lacks relevant algorithms for infant face occlusion detection and there is no method for early warning of infant suffocation or sudden death. The positioning algorithm has achieved excellent baby face occlusion detection results in small baby face occlusion data sets, and can give early warning of infant suffocation or sudden death by returning the occlusion information of key points on the baby's face
