Abstract

The invention discloses a sleeping-posture judgment method based on MPU-6050. The sleeping-posture judgment method includes the steps that acceleration data and angular speed data of a to-be-detectedperson in the sleeping process are obtained; the obtained acceleration data and the obtained angular speed data are subjected to Kalamn filtering, noise is removed, and thus rotation matrix data is obtained; the acceleration data and the angular speed data are fitted with the complementary filtering algorithm, the fitted data is resolved through a quaternion differential equation, the quaternary posture number is obtained, and is unitized, and eulerian angles are finally obtained; three eulerian angle data series are cut with the sliding window method, and characteristic values are extracted;ranges of the characteristic values of the three eulerian angles are subjected to posture division with the decision tree method, and the sleeping posture of the to-be-detected person is finally judged. According to the sleeping-posture judgment method based on the MPU-6050, the sleeping posture is effectively detected, and the method can assist persons in improving the sleeping quality and promoting good health.

Description

Technical field [0001] The present invention relates to the field of smart home, and in particular to a sleep posture determination method based on MPU-6050. Background technique [0002] Health is an eternal topic in human life. A healthy life is inseparable from adequate sleep. Sleep can promote the recovery of physical strength and brain power and the consolidation of memory. It is an indispensable part of life activities. However, many people wake up feeling dizzy, have back pain, and feel exhausted. The reason is often caused by improper sleeping posture. Therefore, choosing the correct sleeping posture is an important prerequisite for improving sleep quality and maintaining good health. [0003] Sleeping posture is one of the ways to ensure good health and relieve fatigue. By detecting body activity and posture information during sleep, and based on the sleep posture determination algorithm, the sleep posture during sleep is determined. [0004] Currently, there is ...
