Problems solved by technology

[0004] However, electrocardiography must use electrodes and chest straps to contact the subject. Optical plethysmography usually requires special light sources (such as infrared light, etc.) and fingertip spring clips to act on the subject. The implementation of heart rate detection is difficult. Moreover, electronic devices such as electrodes have a lifespan, which may affect the accuracy of heart rate detection

Embodiment approach

[0082] As an implementation, the Gaussian standard deviation σ is assigned according to the following formula 3:

[0083]

[0084] Wherein, f is the preset frequency of interest, and r is the frame rate of the face video data.

[0085] Further, the filtering parameters also include a time-domain window width of Gaussian derivative filtering, and in this embodiment, the time-domain window width of Gaussian derivative filtering is set to r / 4f.

[0086] Step S212: Perform Gaussian derivative filtering on the original facial color change signal according to the filtering parameters to obtain the facial color change signal.

[0087] After the computer equipment determines the filter parameters of the Gaussian derivative filter DF(t), the original facial color change signal can be denoised and filtered according to the Gaussian derivative filter DF(t), and the interference noise in the original facial color change signal is filtered out. Get facial color change signal.

Abstract

The invention relates to a heart rate detection method and apparatus, computer equipment and a readable storage medium. The heart rate detection method comprises the following steps: acquiring face video data of a testee, and extracting an original face color change signal corresponding to the testee from the face video data; performing denoising and filtering on the original face color change signal to obtain a face color change signal; and extracting a pulse wave signal corresponding to the testee from the face color change signal, and acquiring heart rate data of the testee according to thepulse wave signal. By adopting the method, the detection precision of heart rate detection can be improved.

Description

technical field [0001] The present invention relates to the technical field of heart rate detection, in particular to a heart rate detection method, device, computer equipment and readable storage medium. Background technique [0002] Heart rate is an important indicator reflecting the physiological health status of the human body, and has important applications in clinical research on cardiovascular diseases, physical exercise and other fields. [0003] In traditional heart rate detection methods, electrocardiography, optical plethysmography, and the like are generally used. Among them, electrocardiography is mostly used in clinical research, and optical plethysmography is a method for obtaining cardiovascular pulse waves by using changes in reflected light and transmitted light, and is often used in detecting exercise heart rate. [0004] However, electrocardiography must use electrodes and chest straps to contact the subject. Optical plethysmography usually requires spec...
