METHOD FOR MEASURING PHYSIOLOGICAL INDICES
Document Type and Number:
WIPO Patent Application WO/2022/182156
Kind Code:
A1
Abstract:
A method for measuring a physiological indices is disclosed. A method, which is performed by one or more processors, for measuring physiological indices of a subject by using an artificial neural network in a non-contact manner, according to an embodiment, may comprise the steps of: obtaining a plurality of image frames of the subject; obtaining a first color channel value, a second color channel value, and a third color channel value for at least one image frame included in the plurality of image frames; calculating a first difference value and a second difference value for the at least one image frame included in the plurality of image frames on the basis of the first color channel value, the second color channel value, and the third color channel value, wherein the first difference value represents the difference value between the first color channel value and the second color channel value for the same image frame, and the second difference value represents the difference value between the first color channel value and the third color channel value for the same image frame; obtaining, for a first image frame group obtained over a first preset time, a first characteristic value on the basis of the first difference value for at least one image frame included in the first image frame group; obtaining a second characteristic value on the basis of the second difference value for the at least one image frame included in the first image frame group; obtaining time series data on the basis of the first characteristic value and the second characteristic value; obtaining biosignal characteristic data on the basis of the time series data; and obtaining physiological indices for the subject by using physiological indices acquisition model on the basis of the biosignal characteristic data.
