A desktop naked-eye 3D display system

Abstract

The embodiment of the invention discloses a desktop type naked eye 3D display system. The system comprises a high-speed projector, a light field function screen divided into the preset number of zones, and a rotating device used for driving the light field function screen to rotate. The high-speed projector refreshes parallax sub-graphs with the number equal to the preset number after being encoded to the corresponding zones on the light field function screen respectively, wherein the parallax sub-graphs are received from image processing equipment, and refreshing frequency is matched with rotating speed of the light field function screen. The light field function screen enables the parallax sub-graphs received by all the zones to be defected by a preset deflection angle and diffused by the corresponding preset diffusion angle in the preset direction, so that a three-dimensional image is formed. By the application of the embodiment, the large-size and high-resolution 3D image is obtained.

Description

Technical field [0001] The present invention relates to the field of naked eye 3D display, in particular to a desktop type naked eye 3D display system. Background technique [0002] Autostereoscopic display provides a new type of stereoscopic observation method. Its biggest advantage is that it can experience real three-dimensional stereoscopic images without resorting to any auxiliary means. Achieving autostereoscopic display is a complex and high-tech process. The more disparity maps it displays, the stronger the stereoscopic perception is observed. [0003] Although the existing naked-eye 3D display system based on high-speed projector and rotating screen can achieve 3D viewing within 360 degrees, this system has two obvious shortcomings: [0004] (1) There are high requirements for the refresh rate of high-speed projectors, which means that the rotating screen must be rotated at a certain speed. When the screen area of ​​the rotating screen is large, it will cause a large moment...

Problems solved by technology

[0004] (1) There are high requirements for the refresh rate of high-speed projectors, which means that the rotating screen must rotate at a certain speed. When the screen area of ​​the rotating screen is large, it will cause a large moment of inertia and cannot be realized.

[0005] (2) The rotating screen is composed of a Fresnel lens with a large space. Since the information reproduction is based on viewpoint imaging, it cannot provide the physical depth of the real object, and due to the influence of aberration, the resolution of the final composite image will be large. to drop
