Title:
HEART RATE MEASUREMENT METHOD AND APPARATUS, AND ELECTRONIC DEVICE AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2023/061042
Kind Code:
A1
Abstract:
The present disclosure relates to a heart rate measurement method and apparatus, and an electronic device and a storage medium. The method comprises: determining a thermal-imaged image sequence that comprises a plurality of thermal-imaged images, which are sequentially collected, wherein the thermal-imaged images are images for representing a temperature distribution in a target region of a human body; determining a feature value of a region, in which a vessel is located, in at least one thermal-imaged image, so as to determine a temperature change signal according to a positional order and a corresponding feature value, and obtain a temperature change of a vessel in the target region of the human body; and on the basis of a characteristic of the temperature of a vessel changing along with the diastole and systole of a heart, further determining, according to the temperature change signal, the heart rate of a human body that is subjected to thermal-imaged image collection. By means of the embodiments of the present disclosure, a thermal-imaged image of a human body can be collected, and the heart rate can be determined according to a temperature change of a vessel therein, so as to realize non-contact measurement of the heart rate. Moreover, the thermal-imaged image of the human body can be collected, only by means of a thermal-imaged image collection apparatus, for heart rate measurement, such that the manufacturing cost is low, and the universality and the portability are good.
