Abstract

The invention discloses a heart rate estimation method, device, equipment and system and a storage medium. The method comprises the following steps: respectively controlling each heartbeat acquisition device to acquire a heartbeat physiological signal of a user; performing signal preprocessing on each heartbeat physiological signal to obtain a synchronous heartbeat physiological signal; extracting a heartbeat interval sequence of each synchronous heartbeat physiological signal, wherein the heartbeat interval sequence is a sequence formed by a time interval between every two adjacent wave crests in the synchronous heartbeat physiological signals; and performing weighted summation on the heartbeat interval sequences of the synchronous heartbeat physiological signals to obtain a final heartbeat interval sequence, and estimating the heart rate of the user based on the final heartbeat interval sequence. According to the technical scheme, the heart rate of the user can be estimated by combining the heartbeat physiological signals, collected by an image collecting device, a wearable device and an electrode patch, of the user, the detection error caused by untight attachment of a single sensor is reduced, and the accuracy of heart rate detection in the vehicle driving scene is improved.

Description

technical field [0001] Embodiments of the present invention relate to the field of physiological parameter detection, and in particular, to a heart rate estimation method, device, equipment, system and storage medium. Background technique [0002] The pace of modern life is fast, and people use cars more and more frequently and for more time. At the same time, due to the neglect of physical health problems, the frequency of driver fatigue driving or sudden illness or traffic accidents is also increasing. Therefore, real-time monitoring of driving physiological parameters (such as heart rate) is very necessary. [0003] In the prior art, a single sensor is often used to detect heart rate. However, due to the complex environment in the vehicle, the user's actions during vehicle driving may cause incomplete contact between the sensor and the user, resulting in inaccurate heart rate detection results that cannot reflect the user's actual physiological heart rate changes. Con...
