Respiration rate and heart rate extraction method based on human body micro-motion signals

The invention discloses a respiration rate and heart rate extraction method based on a human body micro-motion signal, which comprises the following steps of: acquiring weak motion signal data of a human body caused by respiration and heartbeat by using a sensitive piezoelectric sensor in a quiet state, especially a sleep state, and reducing interference signals; obtaining the breathing rate and the heart rate of the testee through continuous updating and segmented calculation of the sampled data samples; continuously performing the detection process for several hours for a long time, continuously collecting data, and continuously obtaining calculation results within a short time after detection is started. The detection process does not interfere with the physiological activity process of the detected person, detection is easy to implement, stable, objective and accurate results are obtained, real and objective evaluation can be given, and the health quality can be effectively improved. 本发明公开了一种基于人体微动信号的呼吸率和
