摘要：
A heart rate measurement method based on a plurality of groups of light sources (200) and a wearable device for implementing the method. The heart rate measurement method based on the plurality of groups of light sources (200), comprises the following steps: receiving a first optical signal emitted by a group of starting light sources (200) reflected by a human body (S1)； performing digital filtering processing on the first optical signal so as to obtain a first photoelectric signal comprising a direct current component and an alternating current component (S2)； and selecting a group of light sources (200) from at least two groups of light sources (200) according to a ratio of the direct current component to the alternating current component and a first pre-set rule, and measuring a heart rate during motion using the one selected group of light sources (200), wherein there are different distances between each group of light sources (200) and an element (201) for receiving the optical signal emitted by the light source (200) reflected by the human body (S3). By arranging a plurality of groups of light sources (200) and using a measurement result of a group of starting light sources (200) to select a group of suitable light sources (200), a heart rate is measured under the selected light sources (200), and thus a measurement result is more accurate.La présente invention concerne un procédé de mesure de rythme cardiaque fondé sur une pluralité de groupes de sources de lumière (200) et un dispositif portatif pour mettre en œuvre le procédé. Le procédé de mesure de rythme cardiaque fondé sur la pluralité de groupes de sources de lumière (200), comprend les étapes suivantes : recevoir un premier signal optique émis par un groupe de sources de lumière (200) de départ réfléchies par un corps humain (S1) ； effectuer un traitement de filtrage numérique sur le premier signal optique afin d'obtenir un premier signal photoélectrique comprenant une composante de courant continu e
