Panoramic space three-dimensional display device simultaneously having horizontal and pitching multiple visual fields

Abstract

The invention discloses a panoramic space three-dimensional display device simultaneously having the horizontal and pitching multiple visual fields. The device comprises a high-speed projector, a selective transmission type directional diffusing screen, a reflecting mirror system and a rotating device, wherein the selective transmission type directional diffusing screen can control the diffusing angles of emergent light in different directions, so observers can see binocular parallax images in different visual angles in different positions in both the horizontal direction and the vertical direction, and the three-dimensional display of three-dimensional objects in the panoramic space can be realized. The panoramic space three-dimensional display device simultaneously having the horizontal and pitching multiple visual fields provided by the invention can display the horizontal periscopic images in 360 degrees in the three-dimensional scene, and can simultaneously provide the polyzonal in-site images in the pitching direction to realize the three-dimensional display. Based on the three-dimensional display system of the invention, the visual spatial three-dimensional perfect display with the space eliminating and hiding function for multiple persons to watch by naked eyes in the 360-degree surrounded way can be realized.

Description

technical field [0001] The invention relates to a display device, in particular to a three-dimensional display device in a panoramic space with multiple fields of view in horizontal and pitch. Background technique [0002] People's three-dimensional perception of objects is generated through a variety of depth cues, mainly including binocular parallax, motion parallax, adjustment, etc. Optical devices or structures that can produce binocular parallax can allow observers to produce three-dimensional stereoscopic vision. With the advancement of science and technology, the display technology is gradually developing from the traditional two-dimensional display to the new three-dimensional three-dimensional display. Currently, 3D display technologies mainly include stereoscopic 3D display, automatic stereoscopic 3D display, holographic 3D display and volumetric 3D display. The application range of 3D display technology is also very wide, and it has good prospects in many aspect...

Problems solved by technology

However, these currently proposed methods have a common feature that although these methods can provide the space occlusion (blanking) effect required by the actual three-dimensional display, they can only provide the spatial three-dimensional display of parallax in the horizontal 360° direction. However, it cannot provide more spatial three-dimensional display information of the pitch field of view.
