Naked eye three-dimensional display method and device based on vibration grating

Abstract

The invention relates to the technical field of naked eye three-dimensional display, in particular to a naked eye three-dimensional display method and device based on a vibration grating. The naked eye three-dimensional display method and device based on the vibration grating aim to meet the needs of the limit of a large three-dimensional watching visual area or a non-three-dimensional watching visual area and three-dimensional image high-resolution display. According to the technical scheme, the naked eye three-dimensional display method based on the vibration grating comprises the following steps that (1) a double-viewpoint three-dimensional composite image is manufactured through a three-dimensional image composite method based on a pixel unit; (2) the grating is manufactured, and the grating is placed in front of or behind a 2D display screen; (3) the grating structure obtained in the step (2) is vibrated in the horizontal direction, the inclined direction and the vertical direction according to certain speed, or is vibrated according to a specifically-designed vibrating curve or with a sub-pixel, or a pixel, or a plurality of pixels or a plurality of sub-pixels as a basic unit; (4) the double-viewpoint composite image is changed along with the change of the vibrating grating structure, the vibrating direction and the vibrating rule. The naked eye three-dimensional display method and device are mainly applied to naked eye three-dimensional display.

Description

technical field [0001] The present invention relates to the technical field of naked-eye three-dimensional display, in particular to a device and principle for increasing the stereo viewing area of ​​naked-eye three-dimensional display under the premise of maintaining high resolution of stereoscopic images. Specifically, it relates to a naked-eye three-dimensional display method and device using a vibrating grating. technical background [0002] Glasses-free stereoscopic display technology has developed rapidly in recent years. Stereoscopic display is favored by people because of its large amount of information and good visual effects. It has broad application prospects in 3D movies, 3D TV, industrial detection, medical inspection, aerospace technology, and entertainment performances. [0003] Since the naked-eye stereoscopic display technology does not require the viewer to wear any auxiliary visual aids, it can bring people more freedom and a better visual experience than...

Problems solved by technology

When K=8, the horizontal resolution of the stereo image is The vertical resolution is That is to say, 1 / 8 of the sub-pixels in the screen image display one of the 8 viewpoint images, which greatly reduces the resolution of the stereoscopic image

Compared with the dual-viewpoint naked-eye stereoscopic display, the multi-viewpoint naked-eye stereoscopic display sacrifices the resolution of the stereoscopic image in exchange for a larger stereoscopic viewing area. Stereoscopic Viewing Area Requirements

Although the multi-viewpoint naked-eye stereoscopic display can provide the viewer with greater freedom of viewing compared with the dual-viewpoint stereoscopic display, the stereoscopic viewing area provided to the viewer is still discontinuous, that is to say, when the position of the viewer moves , you will see a pseudo-stereoscopic image in some areas
