Infant sleeping posture intelligent identification method and device based on thermal infrared imaging

Abstract

Disclosed are an infant sleeping posture intelligent identification method and device based on thermal infrared imaging. The device includes a thermal infrared image acquisition module, a video interface, a thermal infrared image identification and processing module and an early warning module. The infant sleeping thermal infrared image acquisition module acquires thermal infrared images in an infant sleeping process in a real-time manner through a thermal imager. The thermal infrared images are transmitted to the thermal infrared image identification and processing module through the video interface. The thermal infrared image identification and processing module detects the position of a nose hole or an oral cavity and a head area position of the infant and judges a head sleeping position of the infant according to the detected position of the nose hole or oral cavity, relative to the head area. When the judgment result is sleeping postures which are dangerous or have potential safety hazards in that the infant is covered by clothes or the infant sleeps on the stomach and the like, the early warning module is triggered to output early warning information to notify a guardian. Non-contact and radiation-free guardianship is carried out on infant sleeping without using infrared emitter to emit infrared light so that no effect or harm is caused on the infant or sleeping of the infant.

Description

technical field [0001] The invention relates to a method and device for intelligently identifying sleeping postures of infants based on thermal infrared imaging, and belongs to the field of monitoring and monitoring of infants. Background technique [0002] Parents attach great importance to baby safety monitoring. Baby sleeping posture monitoring is an important part of baby safety monitoring. Babies covered by clothes or sleeping on their stomachs can easily cause suffocation of babies. Guardians should promptly and effectively discover and deal with similar important events. The existing baby sleep monitoring technology mainly uses video monitoring, which requires the guardian to actively pay attention to the display terminal at all times. Like manual monitoring, it is easy to cause important baby events not to be discovered and processed in time, especially when the guardian is asleep at night. There are also very few technologies that attempt to analyze surveillance vid...
