Problems solved by technology

The contact heart rate measurement method needs to place sensors on certain parts of the body and needs to be in contact with the subject's body surface. This direct connection measurement method limits the mobility of the user and may cause discomfort and inconvenience to the user , these methods are also not particularly suitable for neonates or patients with skin lesions
Additionally, some devices may only be operated by medical professionals and are not intended for daily use by patients

Embodiment Construction

[0078] In order to understand the above-mentioned purpose, features and advantages of the present invention more clearly, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0079] A non-contact heart rate measurement method based on face video, which specifically includes the following steps:

[0080] ——Video collection: continuous video recording of the face to be tested;

[0081] ——Face detection: detect and recognize the face data information in the recorded video, and obtain the face area of ​​the image frame by frame; after the video capture is completed, determine the position of the face in the image, and signal for the selected area of ​​interest Prepare for processing. In order to extract the periodic change information of human skin color, using face detection method is the key to eliminate the background area of ​​the face and locate the region of interest (ROI).

[0082] ——Regi...

Abstract

The invention provides a non-contact heart rate measurement method based on a face video, and relates to the technical field of biomedical information processing, and the method specifically comprises the following steps: video acquisition; detecting a human face; selecting a region of interest; rGB channel separation and space averaging and preprocessing; a fixed point (Fixed-Point) algorithm is adopted; carrying out improved adaptive noise complete set empirical mode decomposition; and heart rate extraction. The non-contact heart rate measurement system based on the face video comprises a video acquisition module, a face recognition and tracking module, a heart rate calculation module and a result display module. According to the method, a signal processing method combining independent component analysis and an empirical mode decomposition algorithm is adopted, non-contact heart rate detection can be achieved, and the accuracy and efficiency of heart rate detection can be improved.

Description

technical field [0001] The invention relates to the field of biomedical information processing, in particular to a non-contact heart rate measurement method and system based on human face video. Background technique [0002] According to the statistics of the World Health Organization (WHO), the number of deaths due to cardiovascular diseases is more than that of other diseases every year. Cardiovascular diseases have become an important factor affecting people's quality of life. Research on the prevention and treatment of cardiovascular diseases shows that most cardiovascular diseases are preventable and monitorable. Heart rate is a physiological indicator closely related to cardiovascular diseases, so heart rate detection is particularly important for the monitoring and prevention of cardiovascular diseases. As the population ages further, it would be helpful for doctors to allow their patients to track factors such as heart rate more continuously, which would allow docto...
