Problems solved by technology

However, because the stereoscopic technology in the general sense is a false three-dimensional technology, there is a problem of inconsistency between the image focusing distance and the convergence distance, which is easy to cause visual fatigue of the observer, and is limited by the number of parallax images that the display system can provide. Display viewing angles that can be achieved with video technology are often limited

Embodiment Construction

[0040] Based on stereoscopic technology and observer tracking technology, the present invention designs an interactive full-view three-dimensional image display system through reflection scanning of a rotating mirror.

[0041] The system optical path structure using a single fixed modulation device 11 and a single rotating mirror 30 is as follows figure 1As shown: the rotating platform 20 rotates around the system optical axis z-axis; the projection unit 10 is composed of a two-dimensional light modulator 11, a conversion lens 12 and a diffraction element 13, which are used to make the optical path of the projection unit 10 bend along the optical path transmitted along the folded line as required Turning unit 40 is made up of two reflecting mirrors 41 inserted in the optical path of projection unit 10, wherein diffraction element 13 and optical path refraction unit 40 rotate synchronously with rotating platform 20; The mirror 30 is reflected to the observer, and the rotating m...

Abstract

The invention relates to the technical field of three-dimensional image display, and in particular relates to an interactive 360-degree visible three-dimensional display system and an interactive 360-degree visible three-dimensional display system method capable of being implemented based on the stereological technique and time-division multiplex technology. The full-view three-dimensional display system based on the stereological technique comprises a rotating platform, a projector unit, a rotating mirror, a light path reflecting unit, a confocal lens unit, an observer positioning unit, a space mouse unit and a control unit; and the method comprises the following steps in sequence: reasonably designing a parallax image projection light path; spatially separating a distribution space of the protection parallax image and a target image display area; and introducing a space mouse into the target image display area, thus realizing the interactive three-dimensional image display, wherein the space mouse can be used for indicating the display of a three-dimensional image and operating a menu.

Description

technical field [0001] The invention relates to the technical field of three-dimensional image display, in particular to an interactive 360° visual three-dimensional display system and method based on stereoscopic technology and time-division multiplexing technology. Background technique [0002] Because two-dimensional display is difficult to clearly and accurately express the depth information of the third dimension, people have been working on the research of display technology that can display three-dimensional scenes - three-dimensional image display technology. At present, the main three-dimensional technology is stereoscopic three-dimensional image display technology, which provides two-dimensional plane images with different perspectives to the observer's binoculars, and synthesizes them by the human brain to obtain three-dimensional display effects. However, because the stereoscopic technology in the general sense is a false three-dimensional technology, there is a ...
