Sleeping posture spine form testing method without interference with sleep

Abstract

The invention discloses a sleeping posture spine form testing method without interference with sleep. The sleeping posture spine form testing method without interference with sleep is characterized by comprising the following steps. Firstly, a digital human body model is constructed based on personalized human body size. Secondly, man-bed interface sunk shape data is abstracted based on a personalized human body in sleep so that a sunk shape data model is set up. Thirdly, the digital human body model and the human-bed interface sunk shape data model are matched so as to obtain sleeping posture spine form. The sleeping posture spine form testing method without interference with sleep overcomes the defect that a horizontal sleeping posture can not be tested with the prior spine form testing art. The digital human body model and the human-bed interface sunk shape data model are matched to carry out a sleeping posture spine form test and the method is suitable for testing and estimating all sorts of sleeping posture spine forms. The sleeping posture spine form testing method without interference with sleep overcomes the defect that a subject is required to keep a specific posture and position in the prior spine form testing art or a specific testing device is used for carrying out a test and can carry out a natural sleeping posture spine form test in all beds or bed cushions.

Description

technical field [0001] The invention relates to a method for testing the shape of the spine in a sleeping position without disturbing sleep, which is applied to the performance test of a mattress. Background technique [0002] Inadequate support of the back (especially the spine) during sleep is an important cause or aggravation of non-characteristic low back pain. The ideal spinal support condition is to keep the spine in a state of natural curvature, and the lumbar curve is slightly flatter than the standing posture. However, the shape of the spine in the sleeping position is not only related to the mechanical properties of the mattress, but also to individual factors such as body shape and weight distribution. Therefore, the humanized design of spinal support must be based on the individual human body. In addition, the human body will adjust the sleeping position consciously or unconsciously during sleep, and different groups of people have different sleeping position pr...

AI Technical Summary

Problems solved by technology

Among them, the anatomical landmark detection method and the geometric tool test method need to be in contact with the human body, and require certain implementation experience, while the three-dimensional scanning method does not need to be in contact with the human body, but the surface of the back of the human body must be visualized. It is suitable for the spine shape test in the supine sleeping position, and it is not suitable for the test of the spine shape in the natural sleeping position during the real sleep process

There is also a technique that uses a specific device for spine shape testing. This technology requires the subject to perform the test in a specific lying position, that is, the curve of the spine is required to fall on the sensor of the test device. Therefore, it is impossible to test the real sleeping position. , and it is impossible to test and evaluate real mattresses or bedding
