One-dimensional integrated imaging display method based on special-shaped cylindrical lens grating

Abstract

The invention discloses a one-dimensional integrated imaging display method based on a special-shaped cylindrical lens grating, and belongs to the technical field of free three-dimensional display. The invention designs a true three-dimensional display method with multi-view, large-view and high-definition based on a staggered discrete cylindrical lens grating. Firstly, a viewpoint image is obtained through real shooting or a virtual model, the viewpoint image is displayed on a display panel after being processed through a stereogram synthesis algorithm, a staggered discrete cylindrical lens grating and a holographic diffusion sheet are sequentially placed at the proper positions in front of the display panel, and the optimal viewing effect is achieved by designing and matching various parameters of all the devices. By designing the staggered discrete cylindrical lens grating and using the holographic diffusion sheet, three-dimensional display with continuous parallax, dense viewpoints, wide viewing angle and high definition is realized, the problem of small viewing angle of a single viewing area in traditional cylindrical lens grating three-dimensional display is solved, and the three-dimensional display effect is superior to that of a traditional one-dimensional integrated imaging display mode.

[0002] As a hot technology, 3D stereoscopic display technology has attracted the attention of a large number of researchers at home and abroad. Various research institutions have invested a lot of manpower and material resources in research and exploration, and have proposed a variety of stereoscopic display solutions, which are widely used in the current market. Most of the 3D display devices use the principle of binocular parallax, and need to wear corresponding glasses or head-mounted devices to achieve stereoscopic display. , will produce dizziness and discomfort, and long-term viewing may even cause harm to health. Therefore, free stereoscopic display technology without auxiliary equipment has become the 3D display method that people pursue.

[0005] The traditional one-dimensional integrated imaging method can produce stereoscopic display effects, but there are defects such as cyclic jumping of viewing zones, parallax inversion, and small viewing angle of single viewing zone. The existence of this phenomenon leads to the parallax inversion zone at the edge of the adjacent viewing zone, so that the observer cannot watch the correct parallax image in this zone. The above three defects are currently restricting the one-dimensional integrated imaging technology. Three Important Factors for Development
