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
The present invention relates to three-dimensional display apparatus, relate in particular to a kind of 360 ° of suspending type stereoscopic vision three-dimensional display apparatus.
Background technology
3-D display is different from the two dimension demonstration will bring visual depth perception to the beholder by the whole bag of tricks exactly, make its nature or obtain the information of third dimension degree in the picture artificially, the nature of this obtain manner and nature just have the difference of very three-dimensional and false three-dimensional (accurate in other words three-dimensional) for the beholder.Dimension display technologies develops into and has produced a large amount of achievements today, and these achievements roughly can be divided into hologram three-dimensional demonstration, body 3-D display, stereoscopic 3-D display etc.Holographic technique can produce Space very true to nature, but its high-resolution spatial light modulator of needs and superfast data handling system aspect dynamic demonstration, these two factors have greatly limited this makes this development of technology, makes it can't enter practical application well at present.Body 3-D display and stereoscopic 3-D display all have reasonable display device at present and occur, yet the display device based on these two kinds of methods mostly relies on rotating screen to satisfy the requirement that full visual angle is watched, so display device structure relative complex cost is also relatively more expensive.VIZOO company discloses a kind of floated display device of pyramid-like structure in US2008/0144175A1, this device is based on the reflection image theory, by four catoptrons, plane picture above or below the catoptron is imaged on the center of pyramid-like structure, can realize that 360 ° of full angles watch, the image that this simple mechanism projects remains a plane picture, and the depth information of object can't be provided to the beholder.
Based on this, we incorporate stereoscopic 3-D display in the scheme of VIZOO company, have proposed a kind of 360 ° of simple and practical suspending type stereoscopic vision three-dimensional display apparatus.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, a kind of 360 ° of suspending type stereoscopic vision three-dimensional display apparatus are provided.
360 ° of suspending type stereoscopic vision three-dimensional display apparatus comprise stereoscopic display screen of many viewpoints and the pyramid catoptron of placing successively, the stereoscopic display screen of many viewpoints is square and the delta-shaped region that is divided into four independent displaying by the mode that diagonal line intersects, and correspond respectively to four faces of pyramid catoptron, the stereoscopic display screen of many viewpoints is cylindrical grating screen, bicylindrical grating screen or double aperture slit grating screen.
Described cylindrical grating screen is made of display surface and the transmission-type cylindrical grating of Projection Display, LCD or PDP.Bicylindrical grating screen comprises first cylindrical grating and second cylindrical grating of two identical outside parallel placements of cylinder, the raster unit of the raster unit of first cylindrical grating and second cylindrical grating is corresponding one by one, the bicylindrical grating shields a plurality of projectors of a side the centre of the image projection of different points of view to first cylindrical grating and second cylindrical grating, in a plurality of one to one viewpoints of opposite side generation of bicylindrical grating screen.Double aperture slit grating screen comprises first slit grating and second slit grating of two identical parallel placements, the raster unit of the raster unit of first slit grating and second slit grating is corresponding one by one, the double aperture slit grating shields a plurality of projectors of a side the centre of the image projection of different points of view to first slit grating and second slit grating, in a plurality of one to one viewpoints of opposite side generation of double aperture slit grating screen.The pyramid catoptron is a hollow positive rectangular pyramid or hollow positive truncated rectangular pyramids shape, and the side of pyramid catoptron and the angle of bottom surface all are 45s, and all make with partial reflection part transmission-type material all sides.
Advantage of the present invention is simple in structure, and many viewpoint splicings realize 360 ° of surrounding watch, can realize that the strong large-area three-dimensional of stereoscopic sensation shows.
