Abstract

The invention discloses a heart rate measurement method and device, and a readable storage medium. The method includes the following steps: acquiring a video stream including a face image of a personto be tested; performing data processing on a selected video frame in the video stream to obtain human face data; and performing data extraction according to the human face data of the selected videoframe and a frame before the selected video frame to obtain a pulse wave signal of the person to be tested. The method provided by embodiments of the invention obtains the pulse wave signal of the subject by data extraction of the human face data of the selected video frame and the frame before the selected video frame, and can solve or partially solve the accuracy problem of current non-contact measurement.

Description

technical field [0001] The invention relates to the field of physiological characteristic measurement, in particular to a heart rate measurement method, device and readable storage medium. Background technique [0002] Heart rate is an important physiological indicator of the human body, and the level and change trend of the heart rate can often reflect the health status of the human body. At present, the main detection methods for heart rate can be divided into two types: contact type and non-contact type. Various contact measurement methods, such as electrocardiographic signal (ECG) detection technology, laser Doppler technology, microwave or millimeter wave Doppler radar and photoplethysmography technology, have played an important role in the field of clinical physiological signal monitoring. Among them, the first three methods are expensive in equipment and complicated in operation, and are not suitable for daily monitoring of physiological signals. Although the physi...
