| description | The invention relates to a pillow deformation detection method and device. The detection method comprises the following steps: acquiring a distance C from a distance measuring device to each corresponding point on the surface of a pillow; keeping the distance from the distance measuring device to the pillow unchanged after obtaining the distance C, placing the head of the human body on the pillow, and obtaining the distance W from the distance measuring device to the pillow and corresponding points on the surface of the head of the human body; acquiring the head thickness X of the human head; the distance Y = C-W between each point of the head of the human body and the pillow is obtained; and calculating to obtain the concave distance M of the pillow, wherein M = X-Y. On the basis of pillow no-load modeling, pillow load modeling and human head modeling steps, the depression data of the pillow in the using state can be directly obtained through calculation, quantitative detection of the pillow deformation cond |
