Infant monitoring method and device based on robot vision

Abstract

The invention discloses an infant monitoring method and device based on robot vision. The method includes the steps that visual behavior characteristics and physiological parameter characteristics of an infant are detected and represented according to eye video images, lip video images and cheek video images; the parameters are fused and judged to obtain a sleep state detection result of the infant. The device comprises an embedded system used for extracting the visual behavior characteristics and the physiological parameter characteristics of a testee, fusing and processing the characteristic information and sounding an alarm, wherein the visual behavior characteristics include mouth openness frequency, the head position, duration, posture changing frequency of the infant, and the physiological parameter characteristics include pulses and the like. When the sleep state of the infant is abnormal, an alarm signal is output to an alarm, and an abnormal signal is output to a parent or related guardianship personnel at the same time. Only one camera is used for obtaining the information, more information including physiological parameters of the infant is obtained, and health condition monitoring reliability of the infant is greatly improved.

Description

technical field [0001] The invention relates to the field of machine vision, in particular to a machine vision-based infant monitoring method and device. Background technique [0002] The guardianship of infants and young children is something that many parents worry about. Then, there are many deficiencies in the prior art: [0003] The Chinese invention patent (publication number: CN103700215A) proposed by Zhang Yan "a low-radiation wearable baby monitor" can only monitor temperature, humidity and sound; the Chinese invention patent (publication number) proposed by J.P. Tippan : CN103220967A) "Ultra-Wideband (UWB) Baby Monitor for Detecting Baby's Cardiopulmonary Discomfort", adopts microwave to monitor the baby's state, which is not easy to be accepted by parents; Xu Jing's Chinese invention patent (publication number: CN101564302) "based on multi-source Infant sleep agitation monitoring method and detection system based on information fusion ", which monitors temperatu...

Problems solved by technology

[0003] The Chinese invention patent (publication number: CN103700215A) proposed by Zhang Yan "a low-radiation wearable baby monitor" can only monitor temperature, humidity and sound; the Chinese invention patent (publication number) proposed by J.P. Tippan : CN103220967A) "Ultra-Wideband (UWB) Baby Monitor for Detecting Baby's Cardiopulmonary Discomfort", adopts microwave to monitor the baby's state, which is not easy to be accepted by parents; Xu Jing's Chinese invention patent (publication number: CN101564302) "based on multi-source Infant sleep agitation monitoring method and detection system based on information fusion ", which monitors temperature and humidity and thus infers the baby's agitation, but cannot monitor important vital signs; Shen Yunming's Chinese invention patent (public number: CN202614402U) "Infant based on ZigBee Incubator temperature monitoring and alarm system", which can only monitor the temperature of infant incubator; Han Meng's Chinese invention patent (public number: CN103156617A) "thorax and abdomen respiratory motion waveform sensor", a measurement developed by using the giant stress impedance effect of amorphous wire The waveform of human chest and abdomen breathing movement needs to be wrapped in the body of infants and young children, and can only monitor the breathing of infants and young children; the Chinese invention patent (public number: CN1377628) "Intelligent monitoring device for baby warming bed" proposed by Ning Xinbao, A variety of sensors are used to collect parameters such as body temperature and electrocardiogram of the baby being monitored, which belongs to contact measurement. If the measurement time is long, it will easily cause damage to the baby's skin; the Chinese invention patent (public number: CN1564213) "Baby Sleep Monitoring Device" proposed by Sun Ping ", can only monitor the baby's voice; Ding Yongsheng's Chinese invention patent (public number: CN1961829) "A Baby Sleeping Posture Monitoring Bandage", relying on the baby's sleeping straps to monitor the baby's sleeping position is not reliable. , the information obtained is too little; the Chinese invention patent (public number: CN102968753A) "Newborn Baby Care System Based on RFID Technology" proposed by Cui Lingling uses contact sensors and active RFID tags, which belongs to contact measurement, and the measurement time will be lost after a long time. It is easy to cause damage to the baby's skin, and there are long-term close-range wireless radiation, which is not easy to be accepted by parents

[0004] All in all, the existing technologies for monitoring infants and young children either cannot monitor important physiological parameters such as heart rate and respiration of infants and young children, or can only be measured with contact sensors, or use microwave radiation technology to achieve
