Apparatus based on image for detecting heart rate activity and method thereof

Abstract

An apparatus and method based on image for detecting heart rate activity is provided. The method includes: obtaining a plurality of color images; based on a complexion target condition, defining a target region; performing color composition analysis on the target region to obtain red channel signal, green channel signal and blue channel signal, respectively; performing independent component analysis on separate red, green and blue channel signals to obtain separate first independent component signal, second independent component signal and third independent component signal; performing frequency domain transform, signal energy computation and signal optimization processes on separate first, second and third independent component signals to obtain a filter signal, comparing filter signal based on a pre-set condition to determine if target region belonging to a human, and performing a physiological information analysis.

Description

technical field [0001] The invention relates to an image-type heart rate activity detection device and a detection method thereof. Background technique [0002] With the needs of medical care and the development of science and technology, in recent years, many technicians engaged in research and development have improved and integrated technologies such as electronics, information and communication to apply to medical care. For caring for infants or patients, the monitoring of cardiopulmonary function is a very important part. Taking infants and young children as an example, monitoring their heart rate and breathing activity can significantly prevent infants and young children from having heart rate disturbances, causing subsequent chain health problems and even sudden death crises. Therefore, the use of baby monitors for monitoring and care has become popular in European and American countries. On the other hand, most of the clinical medical or bedridden patients’ physiol...

Problems solved by technology

[0004] In fact, the current technical equipment for heart rate activity detection through images usually has the following disadvantages: First, the existing image detection technology has high requirements for the posture and movement of the monitoring object, for example, requires frontal posture and continuous still

However, the existing skin color detection technology has a misjudgment rate of 15-30% for real and fake people. It is easy to misjudge non-real people with similar skin color as real people, causing false alarms and interfering with calculations and interpretations.

In addition, the existing skin color detection technology will distinguish different areas with disjoint pixels as different detection targets, and cannot distinguish the correlation between disjoint skin color areas, or the correlation between each skin color area and the monitoring object, often Causes a gap between information processing and interpretation
