Abstract

The invention relates to a heart rate information acquisition method and device, computer equipment and a storage medium. The method comprises the following steps: dividing a region of interest of each frame of image in a plurality of frames of images according to a preset division mode to obtain a plurality of sub-frame image sequences; acquiring a sub-pulse wave signal of each sub-frame image sequence; according to the sub pulse wave signals, determining weight sequence information of the corresponding divided areas; obtaining pulse wave signals of the plurality of frame images according tothe weight sequence information and the sub pulse wave signals; and determining a heart rate estimated value according to the frequency corresponding to the maximum power spectral density of the pulsewave signal in the preset time period. By adopting the method, the accuracy of heart rate estimation can be improved.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a heart rate information acquisition method, device, computer equipment and storage medium. Background technique [0002] The heart rate is an important indicator reflecting the physiological health status of the human body. In people's daily life, such as physical exercise, the heart rate needs to be detected. However, the traditional electrocardiogram to characterize human heart rate cannot be used anytime and anywhere due to environmental restrictions. [0003] Therefore, people began to study the way of obtaining heart rate. At present, existing heart rate detection methods can obtain heart rate related data based on recognition and certain analysis of face images. However, the traditional method cannot exclude external interference, such as interference caused by facial movement or expression changes, so the obtained heart rate data is inaccurate.
