Title:
NON-CONTACT IMAGE-BASED BLOOD PRESSURE MEASUREMENT METHOD AND SYSTEM BASED ON ADVANCED VISUAL INTELLIGENCE
Document Type and Number:
WIPO Patent Application WO/2022/169312
Kind Code:
A1
Abstract:
According to a non-contact image-based blood pressure measurement method and system based on advanced visual intelligence proposed in the present invention, a neural network is trained with an image sequence captured by a webcam in a non-contact manner to generate a blood pressure measurement model, and the blood pressure of a measurement subject is measured using the blood pressure measurement model. Therefore, since the webcam with which a moving image, that is, an image sequence, is captured in a non-contact manner is used, the blood pressure can be continuously estimated while capturing images with the webcam without contact with a device or another person. Moreover, since the blood pressure is estimated from a subject merely being in front of the webcam, the present invention is highly usable and inexpensive, and sufficient precision can be attained using a neural network algorithm.
