Problems solved by technology

It will also cause the pelvis to expand outward, the femur to turn inward, and the knee joint to turn inward, so that the feet may turn inward and affect the walking posture. In severe cases, it will also cause lordosis, affecting the overall sense of balance and coordination of the body

Embodiment Construction

[0039] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0040] Such as Figure 1-2 Shown, a kind of bad sitting posture monitoring method based on Notch sensor of the present invention, specifically implement according to the following steps:

[0041] Step 1: Collect the sitting posture data of the monitored person based on the Notch sensor;

[0042] Step 1.1: Wear the Notch wearable device, that is, place two sensors at the thoracic spine and lumbar spine of the monitored person to collect sitting posture data;

[0043] Step 1.2: Preprocessing of data. The user's sitting posture data collected by the Notch sensor, including time and Euler angle, is transmitted via Bluetooth. Because the data collected by the sensor is susceptible to external interference, the stability and data accuracy are somewhat insufficient. Di...

Abstract

The invention discloses a bad sitting posture monitoring method based on a Notch sensor. The method includes the following steps: collecting sitting posture data based on the Notch sensor; pre-processing the collected data, removing dirty data, improving the reliability and accuracy of the data, and making the data format meet the requirements; performing feature extraction and selection on the processed data, and forming feature vectors by using the extracted features; establishing various sitting posture models by using the extracted features, monitoring sitting postures of monitored personsin real time based on the various sitting posture models, and finally obtaining classification and identification results; and designing a mobile application to remind users of the sitting postures,and proposing correction suggestions. The scheme of the invention has good accuracy and convenience, is beneficial to protect the cervical vertebra and lumbar vertebra and improve myopia and other diseases caused by the bad sitting postures from the source, improves the sub-health of people, and reduces the medical burden of the society.

Description

technical field [0001] The invention belongs to the field of behavior recognition, and in particular relates to a method for monitoring bad sitting posture based on a Notch sensor. Background technique [0002] In daily work and study, the sitting posture is the posture that lasts the longest. Compared with other postures, the sitting posture consumes less energy, making people less prone to fatigue and convenient for office and study, but maintaining an improper sitting posture for a long time will bring serious harm to human health. According to the survey, about 70%-80% of the sedentary people in our country have long-term improper sitting postures during work and study. Improper sitting postures make the spine in a flexed position or certain specific positions for a long time, which not only increases the pressure in the intervertebral disc of the spine , It will also cause the muscles and ligaments of the spine to be in a state of uncoordinated stress for a long time, ...
