Abstract

The application provides a heart rate detection method and device, computer equipment and a readable storage medium. The method comprises the steps of firstly, obtaining a ballistocardiogram signal change curve, and then calculating an initial feature point corresponding to each wave crest in the ballistocardiogram signal change curve; screening a plurality of feature points as marked feature points from initial feature points, wherein the feature values of the screened feature points are not less than a first threshold value and the time for which the feature values are maintained not to be exceeded reaches a first preset time; and finally, calculating the heart rate according to the interval time between two adjacent marked feature points. In the calculation process, the calculated feature points represent the line length change and consistency of an ascending curve and a descending curve of the wave crest. Compared with an existing algorithm which directly calculates the crest valueof the ballistocardiogram signal change, the amplitude of the feature points is more obvious and more identified. The algorithm provided by the invention aims at 'surface extraction ', so that the specificity of the feature position in periodic signals is remarkably improved, and the accuracy of obtaining the heart rate from the ballistocardiogram signals is greatly increased.

Description

technical field [0001] The present application relates to the technical field of physiological data detection, in particular to a heart rate detection method, device, computer equipment and readable storage medium. Background technique [0002] Existing heart rate detection equipment can use the micro-motion sensor to sense the heart shock signal caused by the user's heart shock, and then perform corresponding calculations on the periodic changes of the heart shock signal through an algorithm, thereby extracting the user's heart rate data. However, the heart shock signal is embodied as a series of envelopes that fluctuate according to periodic actions. The maximum amplitude of the envelope is on the R wave of the heart shock, and there are gradually decreasing amplitude change signals on both sides of the highest peak. Therefore, this The maximum amplitude is not significant, and it is difficult to use a benchmark to distinguish, resulting in low accuracy of the heart rate c...
