Abstract

The invention discloses a signal processing method based on the PPG heart rate measurement technology. The signal processing method includes the steps that a color video is obtained, and a video frame sequence is extracted; all video frames of the video frame sequence are subjected to image processing, and efficient areas of the video frames are determined; according to the efficient areas of the video frames, effective signals are extracted, and noise reduction processing is carried out; signals obtained after noise reduction are subjected to period analysis, and heart rate statistic values are obtained. In addition, the invention provides a signal processing device based on the heart rate measurement technology. The signal processing device comprises an obtaining module, an image processing module, an extracting module, a noise reduction module and an analyzing and processing module, the image processing module is respectively connected with the obtaining module and the extracting module, and the noise reduction module is respectively connected with the extracting module and the analyzing and processing module. According to the signal processing method, measurement signals obtained under multiple disturbed conditions such as movement, lamplight and noise are subjected to pertinence treatment, the signal obtaining accuracy is greatly increased, the application range of the PPG technology is widened, and accurate working in various environments can be achieved.

Description

technical field [0001] The invention relates to the field of signal processing, in particular to a signal processing method and device based on PPG heart rate measurement technology. Background technique [0002] The existing PPG technology can collect video images of the face or other parts of the human body through the camera without contact, detect the difference in the intensity of reflected light after being absorbed by the blood and tissues of the human body, and trace the change rate of the blood vessel volume during the cardiac cycle. The method of signal processing calculates the heart rate from the obtained pulse wave, and realizes the non-invasive continuous non-contact measurement of the heart rate. However, due to the movement of the measurement site, natural light, fluorescent lamps and other interferences, the final measured signal network is weak, and the noise interference and fluctuations are very serious, so the non-contact measurement results of the PPG t...
