Method and device for detecting sitting posture and seat

Abstract

The present invention relates to a sitting posture detection method and device and a seat. An embodiment of the method includes: when the person to be detected is in a sitting posture, using a plurality of strain gauges arranged on the surface of the seat to obtain pressure data; determine at least one of the following characteristics from the pressure data: total pressure characteristics, shape characteristics, pressure distribution characteristics; match the determined characteristics with a preset sitting posture discrimination strategy to obtain the sitting posture category of the person to be detected. This embodiment can realize accurate detection of the sitting posture of the human body without relying on the camera equipment and a large number of pressure sensors arranged on the human body, and without restricting the freedom of human activities.

Description

technical field [0001] The invention relates to the technical field of smart home, in particular to a sitting posture detection method and device and a seat. Background technique [0002] With the popularization of computers, people spend a lot of time in front of the computer. Sitting for a long time will cause long-term fixed compression on the bones and muscles of the spine and buttocks, which will cause irreversible damage to the human body. Therefore, it is necessary to design a device and method for detecting sitting posture, and to collect statistics of the sitting posture data of the user. On the one hand, the user can consciously avoid certain sitting postures and form a good sitting posture habit. In view of the impact of sitting posture on the body, effective exercise methods are provided. For growing minors, the sitting posture during class and study will not only affect the efficiency of class, but also affect the development of their bones. Therefore, sitting ...

Problems solved by technology

[0003] There are mainly two kinds of existing sitting posture detection methods: 1. Machine vision detection method, which uses a camera to take pictures of people’s sitting posture and judges people’s sitting posture through machine vision. This method requires that the human body image is not blocked, and requires that the human body cannot Leaving the field of view of the camera; 2. The body strain gauge method, that is, setting pressure sensors at the main joints of the human body to judge the sitting posture. This method requires a large number of sensors and limits the freedom of human movement.
