Multi-light source heart rate measurement apparatus, method and wearable device

A multi-light source heart rate measurement apparatus, comprising:

• a first optical receiving group, a second optical receiving group, a first light source and a second light source;
• wherein distances between the first light source and the first optical receiving group and the second optical receiving group respectively are both a preset resting and first dynamic heart rate measurement interval, based on the first light source cooperating with at least one of the first optical receiving group or the second optical receiving group, a resting heart rate of a person to be tested in a non-exercise state or a first dynamic heart rate of the person to be tested in a first exercise state is measured;
• a distance between the second light source and the first optical receiving group is a preset resting heart rate measurement interval, and the preset resting heart rate measurement interval is less than or equal to the resting and first dynamic heart rate measurement interval;
• the resting heart rate of the person to be tested is measured based on the second light source cooperating with the first optical receiving group;
• a distance between the second light source and the second optical receiving group is a preset second dynamic heart rate measurement interval, and the preset second dynamic heart rate measurement interval is larger than the resting and first dynamic heart rate measurement interval, a second dynamic heart rate of the person to be tested in a second exercise state is measured based on the second light source cooperating with the second optical receiving group, wherein an intensity of exercise of the second exercise state is greater than that of the first exercise state.
