Solid-angle three-dimensional display possessing 2pi spherical degrees

Abstract

The invention discloses a solid-angle three-dimensional display possessing 2pi spherical degrees. Vertical and horizontal bidirectional parallaxes are simultaneously possessed. A visual area includes 2pi spherical degrees of an upper half portion of a screen rotation area. The display comprises a projector module, a double-sided reflection grating screen, a screen fixing rack, a transmission shaft rod 2, a bevel gear module group, a transfer bar, a horizontal rotation bottom disc, a plane gear 1, a plane gear 2, a motion detection sensor, a transmission shaft rod 1, a motor and an embedded processor. A high speed projector projects projection images of a three-dimensional object to the double-sided reflection grating screen carrying out bidirectional orthogonal rotation motion, wherein the projection images are formed through combining different angle along horizontal 360 degree and vertical 180 degree directions. An observer can observe corresponding images of the three-dimensional object of different horizontal and vertical angles around a display apparatus. By using the solid-angle three-dimensional display possessing the 2pi spherical degrees, many persons can simultaneously watch a displayed three-dimensional object content by using naked eyes through multiple angles.

Description

technical field [0001] The invention belongs to the technical field of volumetric three-dimensional display, and in particular relates to a solid-angle three-dimensional display with 2π steradian. Background technique [0002] As one of the important development directions of display technology in the future, 3D display technology is more and more favored by people. However, most of the current 3D display technologies are plane-based parallax-type 3D display systems, and 3D displays in the true sense rarely appear. [0003] At present, the main 3D display technologies mainly include: parallax 3D display, holographic 3D display, volumetric 3D display and light field reconstruction 3D display. [0004] Parallax-type 3D display generally enables the observer to observe slightly different left and right views with the left and right eyes of the observer by wearing auxiliary tools such as glasses, and uses binocular parallax to generate stereoscopic vision perception. However, ...

AI Technical Summary

Problems solved by technology

[0008] Restricted by the overall structural design, the screen of the common light field reconstruction technology only has the ability to rotate in the horizontal direction, and cannot segment the 3D image in the vertical direction. Therefore, the current light field reconstruction technology can only achieve 360 ​​degrees of objects in the horizontal angle. Field of view image sequence display, so it can only provide 360° surround viewing function in a single horizontal direction, and cannot realize real stereoscopic display
