Abstract

The invention provides a heart rate detection method and device, a storage medium and electronic equipment. The method comprises the steps that a physical state signal of a to-be-detected user is acquired; identifying the body state signal by using a pre-constructed body state identification model to obtain a body state identification result of the to-be-detected user, and selecting a preset number of candidate spectrum peaks from a frequency spectrum of the body state signal; calculating a weight value of each candidate spectrum peak by utilizing a heart rate transition probability model corresponding to the body state recognition result and each candidate spectrum peak; and taking the candidate spectrum peak with the maximum weight value as a heart rate detection result of the to-be-detected user. By applying the method provided by the embodiment of the invention, heart rate estimation can be carried out in combination with the heart rate change trends in different body states, and the heart rate detection precision is effectively improved.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a heart rate detection method and device, a storage medium and electronic equipment. Background technique [0002] Accurate and real-time heart rate detection technology can provide guidance for applications such as clinical medical diagnosis and health risk assessment, and is of great significance in the field of health monitoring. At present, when detecting the user's heart rate, it usually collects some physiological state signals of the user, such as collecting the user's photoplethysmography (PPG) signal, and then finds the heart rate peak in the time domain of the signal or the heart rate in the frequency domain. The search of the spectral peak is used to detect the heart rate. [0003] However, if the user is in motion during heart rate detection, motion artifacts will be introduced into the signal, so motion artifacts need to be removed before heart rate detectio...
