Abstract

The invention discloses a heart rate detection method, which comprises the following steps: detecting light brightness of an environment where a detected object is located; judging whether the light brightness meets preparatory conditions or not, if not, generating infrared light; judging whether the head of the detected object is within a valid measurement working distance, if so, conducting 3D scanning on the face of the detected object so as to establish a model; on the basis of the model established through the 3D scanning, conducting face tracking by virtue of a motion tracking algorithm, and extracting motion data; recognizing the face based on the motion data, and extracting spectrum transformation data, so that original data is constituted; conducting independent component analysis on the original data so as to remove noise; and after removing the noise, conducting waveform analysis on the data through fast Fourier transform, so that real-time heart rate data is obtained. The heart rate detection method disclosed by the invention can reduce the influence of a measurement environment on measurement precision, so that the accuracy of heart rate measurement is improved. The invention also discloses a heart rate detection system.

Description

technical field [0001] The invention relates to the technical field of heart rate detection, in particular to a heart rate detection method and system. Background technique [0002] A study by the Computer Science and Artificial Intelligence Laboratory of the Massachusetts Institute of Technology found that when the heart pumps fresh blood to the head, due to the pressure, the human head will shake slightly that is difficult to distinguish with the naked eye. In the case of a light source, due to the slight shaking of the head, the light refraction angle of the facial skin will change slightly, which will cause the regular change of the skin color of the same skin due to the heart rate. Using this phenomenon, the heart rate can be calculated by detecting the change in the skin color of the face caused by the slight shaking of the human head. Therefore, by analyzing the image of the human face in a video, a detailed and accurate heart rate value can be obtained. [0003] Ba...
