Problems solved by technology

By providing corresponding views to the observer's binocular eyes, traditional stereoscopic technology can realize three-dimensional effect presentation based on binocular parallax technology, but traditional stereoscopic technology is limited by the spatial resolution of display devices. Therefore, the traditional stereoscopic technology can provide Viewpoints are very limited

Abstract

The invention relates to the technical field of three-dimensional image display, and particularly relates to a multi-viewpoint three-dimensional display system and a display method. The system comprises a control unit and a plurality of time division multiplexing projection units with the same type, and all the time division multiplexing projection units are arranged adjacently in a plane or a curved surface; each time division multiplexing projection unit comprises a display screen, a projection lens and a clear aperture array; the clear aperture array is composed of multiple clear apertures and arranged at a projection lens aperture or an image surface; the clear aperture arrays are arranged in a spatial stagger mode; the control unit is electrically connected with the display screen and the clear aperture arrays, at one time point, the control unit gates one clear aperture in the clear aperture arrays, and the display screen is controlled to refresh and display corresponding information. Clear aperture time sequence gating of each clear aperture array is controlled through the control unit, and presentation of multiple viewpoints is realized based on persistence of vision. According to the system and the method of the invention, through spatial-temporal combined multiplexing, presentation of a large number of dense viewpoints can be realized.

Description

technical field [0001] The present invention relates to the technical field of three-dimensional image display, and more particularly, to a multi-viewpoint three-dimensional display system and method. 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. By providing corresponding views for the observer's binocular eyes, traditional stereoscopic technology can realize three-dimensional effect presentation based on binocular parallax technology, but traditional stereoscopic technology is limited by the spatial resolution of display devices. Therefore, the traditional stereoscopic technology can provide Viewpoints are very limited. In order to obtain a better 3D visual experience, traditional stereoscopic 3D display systems need...
