Abstract

The invention provides a three-dimensional reconstruction method and apparatus for human cervical vertebra based on grating projection. The method comprises: obtaining a grating image by shooting a grating projection plane that is formed by projecting a light source on the cervical vertebra and a reference plane via a grating sheet; and performing three-dimensional reconstruction on the cervical vertebra according to the grating image, to obtain cervical vertebra three-dimensional outline information. The method and the apparatus make the obtaining of the cervical vertebra three-dimensional outline information convenient and quick.

Description

technical field [0001] The invention relates to the field of image processing, in particular to a method and device for three-dimensional reconstruction of human cervical spine based on grating projection. Background technique [0002] One-third of a person's life is spent in sleep. As important as sleep is to human beings, pillows are just as important to sleep. The cervical spine of the human body is in direct contact with the pillow, and the cervical spine is closely related to the shoulder and waist muscles, ligaments, and intervertebral discs of the human body. This shows the impact of a suitable pillow on human health. The cervical spine has a lordosis, which is called physiological lordosis. The pillow matches the physiological lordosis of the cervical spine during sleep, so that the normal physiological curvature of the cervical spine can be maintained during sleep. And make the neck skin, muscles, ligaments, intervertebral discs, intervertebral joints, and tissues ...
