Embodiment Construction

[0056] In order to make the object, technical solution and advantages of the present invention more clear and definite, the present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0057] Most of the currently applied face recognition database data is adult facial data, and the recognition methods are mostly aimed at adult test groups. Newborns are immature early risers, and their facial features are quite different from those of adults. In addition, the newborn's face may be covered by a ventilator or a pacifier, resulting in some facial feature points not being recognized. Until it can't be applied to the face detection of infants, because the existing methods are rarely researched on the heart rate characteristics of the newborn test group. Because the normal ...

Abstract

The invention provides a non-contact newborn heart rate monitoring method and system based on a face video. The method comprises the steps that acquiring face video of a newborn; carrying out face detection by using a newborn face local detection algorithm to obtain a newborn face interest region based on eye features; taking the face interest region as a mask, continuously collecting videos underthe mask at a predetermined time, and synthesizing a video at a specified frame rate; inputting the video in the preset time under the mask into an Euler amplification algorithm module, and amplifying the variation amplitude of the pixel value of the frequency band of 2-2.4 Hz; separating the green channel of the amplified video, and processing the green channel to obtain a smoother heart rate signal curve; and performing effective peak detection on the heart rate signal curve, and performing calculation to obtain an average heart rate value of the newborn in the recorded video. Physical discomfort caused by a contact method is reduced to a great extent, meanwhile, heart rate information can be acquired in real time, and heart rate state judgment can be made.

Description

technical field [0001] The invention relates to the field of non-contact heart rate measurement, in particular to a non-contact newborn heart rate monitoring method and system based on facial video. Background technique [0002] Heart rate refers to the number of heartbeats per minute in a normal resting state. The heart rate signal is a physiological signal with important physiological significance and reference value, which can reflect a person's current heart health and psychological state. Sudden Infant Death Syndrome (SIDS) is a phenomenon of unknown cause and the third leading cause of early infant death. It is necessary to use necessary means to promptly warn of events that obviously endanger the life of newborns. Therefore, new technologies are needed to monitor infants' heart rate in real time. [0003] The effective collection of heart rate signals is of great value in the fields of medical monitoring, criminal detection and lie detection. Traditional heart rate ...
