Problems solved by technology

[0007] To sum up, the spatial three-dimensional display in the prior art generally requires the movement of the display medium to realize the spatial scanning of the horizontal 360° field of view, and the spatial position of the displayed three-dimensional scene is the same as or close to the movement area of ​​the display medium, resulting in The 3D scene cannot perform interactive operations such as touch, and cannot meet people's needs for realistic 3D display in space

Abstract

The invention discloses a pitching multi-view angle suspension type panoramic space three-dimensional display device based on a combined screen. The pitching multi-view angle suspension type panoramic space three-dimensional display device comprises a combined deviation diffuser screen, a high speed projector, an image control module, a rotation detection module, a motor and a transmission mechanism, wherein the high speed projector projects level 360-degree view field combined images at different pitching view angles of different three-dimensional objects into different regions on the combined deviation diffuser screen; each region of the combined deviation diffuser screen can control vertical deflection and divergence angles and horizontal divergence angles of incident light rays at different angles, so that observers watching around in different heights can observe three-dimensional images in accordance with viewpoint positions by two eyes; and reproduced three-dimensional scenes are suspended above the combined deviation diffuser screen. The pitching multi-view angle suspension type panoramic space three-dimensional display device has the characteristic that: a plurality of people can watch a horizontal 360-degree full view field from a plurality of view angles by naked eyes, along with space shading and blanking, touch interaction and the like.

Description

technical field [0001] The invention belongs to the technical field of three-dimensional display, and in particular relates to a floating panoramic three-dimensional display device based on combined screens with pitching and multi-view angles. Background technique [0002] At present, the traditional two-dimensional flat panel display and projection display can no longer meet people's demand for display technology, and people need a new display technology that can truly reproduce objective three-dimensional objects. [0003] The relatively mature 3D TVs and 3D movies that have been introduced to the market at present often use visual aids such as glasses to provide binocular parallax images to generate stereoscopic vision. This 3D display only provides information from two perspectives for the observer. The 3D images viewed by the observer at different positions are the same, and they cannot observe different sides of the 3D scene as the position changes. Headache, nausea a...
