360 degree suspending type stereoscopic vision three-dimensional display apparatus

Abstract

The invention discloses a 360-degree suspension type stereo three-dimensional display device, and comprises a multi-viewpoint stereo display screen and a pyramidal reflector which are arranged sequentially. The multi-viewpoint stereo display screen is square and is divided into four triangular areas of independent display by the intersectant mode of diagonal lines, and the four areas respectively correspond to the four surfaces of the pyramidal reflector. The multi-viewpoint stereo display screen is a cylinder integral screen, a bicylindrical integral screen or a double aperture slit integral screen. The invention integrates the principles of multi-viewpoint stereo three-dimensional display and reflection images and can display the anaglyph of at least sixteen viewpoints through split joint in the range of 360 degrees. As all the reflectors are made from partial transmission type materials of reflection parts, images present a good suspension effect. The invention has the advantages of simple structure and realizing 360-degree surrounding watch through multi-viewpoint split joint as well as large area three-dimensional display with intensive third dimension.

Description

technical field [0001] The invention relates to a three-dimensional display device, in particular to a 360° suspended stereoscopic three-dimensional display device. Background technique [0002] The difference between three-dimensional display and two-dimensional display is to bring visual depth perception to the viewer through various methods, so that it can naturally or unnaturally obtain the third-dimensional information in the picture. For the viewer, there is a difference between true three-dimensional and false three-dimensional (or quasi-three-dimensional). The development of 3D display technology has produced a large number of achievements today, which can be roughly divided into holographic 3D display, volumetric 3D display, and stereoscopic 3D display. Holographic technology can produce very realistic spatial effects, but it requires high-resolution spatial light modulators and ultra-high-speed data processing systems in terms of dynamic display. These two factors...

Holographic technology can produce very realistic spatial effects, but it requires high-resolution spatial light modulators and ultra-high-speed data processing systems in terms of dynamic display. These two factors greatly limit the progress of this technology, making it Not yet well into practical applications

Both volumetric 3D display and stereoscopic 3D display have relatively good display devices. However, most of the display devices based on these two methods rely on rotating screens to meet the requirements of viewing from all angles, so the structure of the display device is relatively complicated and the cost is relatively expensive.

In US 2008 / 0144175A1, VIZ00 Company discloses a suspended display device with a pyramid-like structure. The device is based on the principle of reflection and mirroring. Through four mirrors, the plane image above or below the mirror is imaged at the center of the pyramid-like structure. It can realize 360° full-angle viewing. The image projected by this simple device is still a flat image, which cannot provide the viewer with the depth information of the object.
