Description

Sitting posture monitoring method, device and glasses Technical Field The embodiment of the disclosure relates to the technical field of health monitoring, in particular to a sitting posture monitoring method, a sitting posture monitoring device and glasses. Background Teenager stage is a key stage of human spine development and vision formation, and long-term bad sitting posture has become a primary risk factor for inducing spine development abnormality (such as scoliosis and humpback) and vision decline (such as myopia and astigmatism). Along with the increase of the pressure of teenagers in the learning industry, the duration of the case-setting learning is obviously prolonged, the occurrence rate of bad sitting postures is continuously increased, and the physical and health development of the teenagers is seriously influenced, and the learning efficiency and the psychological state of the teenagers are possibly negatively influenced, so that the sitting postures of the teenagers are monitored in real time and effectively and are intervened in time, and the problem of social health to be solved urgently is solved. The contact type monitoring scheme needs that teenagers wear a binding type sensor and a wearable device or a detection module is arranged at contact positions such as a seat and a tabletop, and whether sitting postures are standard or not is judged by sensing the relative positions of bodies and contact parts. However, the teenagers are in an active and active growth stage, the contact type equipment can generate obvious interference on normal learning and activities of the teenagers, and the wearing or using process is complex, so that the teenagers are easy to cause conflict psychology, the teenagers can actively avoid use, and long-term and stable monitoring cannot be realized. The vision monitoring scheme relies on vision acquisition equipment such as a front camera, an infrared camera and the like, and the human sitting posture characteristics are analyzed through an image recognition technology. Because the monitoring scene is mostly private or public study space such as family study room, classroom, and the like, the continuous image acquisition action of front-end camera is easy to infringe privacy of teenagers and surrounding personnel, causes privacy dispute, and is greatly influenced by environmental factors such as light condition, shooting angle, and the like, the monitoring precision is obviously reduced in dim environment or non-frontal shooting scene, and is difficult to adapt to diversified study environment. Therefore, the existing teenager sitting posture monitoring schemes have technical defects which are difficult to overcome, accurate monitoring cannot be realized on the premise of avoiding interference with users and protecting privacy, and the problems of monitoring and intervention of the teenager bad sitting postures are difficult to effectively solve.
