Description
Technical field
The present invention relates to display technologies, it is more particularly related to 3D stereo display technique.
Background technique
3D display technology can be achieved on a kind of display technology of stereo scene true reappearance, can mention respectively for human eye
For different anaglyphs, to make one to generate stereoscopic vision.Usual stereoscopic display is by grating and stereoscopic parallax composograph structure
At.By accurately coupling, stereoscopic parallax composograph pixel can be by grating loss to specified direction, to form viewpoint.
It is when human eye is respectively at different points of view, different anaglyphs can be respectively seen in right and left eyes, to generate stereopsis
Feel.When realizing large scale stereoscopic display, stereo projection apparatus can be used, use projector as stereoscopic parallax composograph
Offer medium.Traditional stereo projection apparatus is in screen frequently with front projection machine mode, i.e. viewer and projector
The same side is projected.A kind of stereo projection apparatus viewer of the invention and projector are distributed in the not ipsilateral of screen and show
Show, convenient for for show surroundings such as outdoor, show windows.
Summary of the invention
The invention proposes a kind of stereo projection apparatus.Attached drawing 1 is the structure principle chart of the stereo projection apparatus.The solid
Projection arrangement is made of the first slit grating, scattering layer, the second slit grating, reflecting mirror and multiple projectors.Described first
It is sequentially placed before and after slit grating, the scattering layer, second slit grating, the multiple projector is placed in close to described
Second slit grating side.The projector can project corresponding anaglyph, and through the mirror imager
Near second slit grating.Have transmissive slit on second slit grating, can by the projector come at
As light beam formation striped, and it is projeced at the scattering layer.The striped that the scattering layer can be formed second slit grating
It is scattered.The striped can be projected again assigned direction in space by first slit grating, to pool viewpoint.
Since in the stereo projection apparatus, multiple projectors point are in different horizontal space positions, then its light
When through the second slit grating, the horizontal space position that imaging beam forms striped on the scattering layer is different.Therefore, first is narrow
Seam grating can will project from the anaglyph of the different projectors and converge to different viewpoint positions.When human eye point
When in different points of view position, corresponding anaglyph can be respectively seen, to realize stereoscopic vision.
If the distance of stereo projection apparatus viewpoint to first slit grating isl 1, the first slit grating to scattering layer away from
From forl 2, the distance of scattering layer to the second slit grating isl 3, the second slit grating to projector imaging in reflecting mirror
Distance isl 4, viewpoint spacing isd 1, projector's spacing isd 2.Preferably, above-mentioned parameter should meet:。
In the present invention, since the stereo projection apparatus is not related to the coupling of anaglyph pixel and optical grating construction, viewpoint
Launching position is only determined by the position of the projector, therefore can directly fix the position of projector in the preparation, and when use only needs
Anaglyph is transported to projector；Since the stereo projection apparatus carries out Projection Display using projector, convenient for real
Existing large scale is shown；Due in the stereo projection apparatus, projector and viewer are distributed in first slit grating, described dissipate
The not ipsilateral of layer and second slit grating is penetrated, therefore convenient for for show surroundings such as outdoor, show windows.

Embodiment
Fig. 1 is the structural schematic diagram of stereo projection apparatus 010 provided in this embodiment, in figure in x coordinate representation space
Horizontal direction, the vertical direction in y coordinate representation space, the direction z indicate the axial direction perpendicular to x-y plane.Please refer to figure
1, the present embodiment provides a kind of stereo projection apparatus 010 comprising the first slit grating 100, scattering layer 200, the second slit light
Grid 300, reflecting mirror 400 and 4 projectors 500.
Below to the present embodiment provides stereo projection apparatus 010 to be further described.
It is sequentially placed before and after first slit grating 100, scattering layer 200, the second slit grating 300, the projector 500 puts
It is disposed adjacent to 300 side of the second slit grating.The multiple projector 500 can project corresponding anaglyph.
Its corresponding relationship are as follows: each projector projects the anaglyph that should be seen that in width viewpoint corresponding with its position respectively.And it passes through
The reflecting mirror 400 images near second slit grating 300.There is transmissive slit on second slit grating 300, it can
The imaging beam that the projector 500 projection comes is formed into striped, and is projeced at the scattering layer 200.The scattering layer 200
The striped that can be formed to second slit grating 300 is scattered.First slit grating 100 can throw again the striped
It is mapped to assigned direction in space, to pool viewpoint.
Fig. 2 is the schematic illustration that the present embodiment realizes stereoscopic display, the horizontal direction in figure in x coordinate representation space, y
Vertical direction in coordinate representation space, the direction z indicate the axial direction perpendicular to x-y plane.Referring to figure 2., due to reflection
The effect of mirror 400, the projector 500 will form mirror image in reflecting mirror 400, then the present embodiment can carry out optics according to Fig. 2
Anaglyph can be projected near the second slit grating 300 by expansion, projector's formed mirror image 510 in reflecting mirror.Due to
In the stereo projection apparatus, the combination point that 4 projectors 500 are formed is in different horizontal space positions, then its light penetrates
When the second slit grating 300, the horizontal space position that imaging beam forms striped on scattering layer 200 is different.Therefore, first
