Specific implementation mode
The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, but the protection model of the present invention
Enclose be not limited to it is as described below.
As depicted in figs. 1 and 2, it is the principle of the present invention block diagram and overall structure diagram, a kind of scene reproduction is holographic to throw
Shadow display system, including stereo display module, secondary light source 3, projection screen 7, motion accompanying drive module 4, eye recognition mould
Block 5 and processor 1；Eye recognition module 5 and processor 1 connect, for positioning 8 position of human eye；Stereo display module and processing
Device 1 connects, and is used for project stereoscopic picture；Secondary light source 3 and processor 1 connect, and are modulated for picture；Motion accompanying drive module
4 connect with projection screen 7 or stereo display module, control projection screen 7 and the movement of stereo display module position, make 8 He of human eye
Stereo display module is in mirror position relative to projection screen 7.
When work, processor 1 controls stereo display module projected picture on projection screen 7, the light projection of secondary light source 3
Onto projection screen 7, the light that light and stereo display module that secondary light source 3 is sent out are sent out generates interference, forms hologram, to
It can watch 3D pictures, eye recognition module 5 that can position 8 position of human eye, by 1 analyzing processing of processor, processor 1 is controlled
Motion accompanying drive module 4 processed acts, and motion accompanying drive module 4 and stereo display module or projection screen 7 connect, and control is vertical
Body display module and projection screen 7 move, and human eye 8 and stereo display module is made, in mirror position, to ensure relative to projection screen 7
Personnel can receive clearly 3D pictures when moving.
Eye recognition module 5 includes video camera and infrared range finder, and video camera identifies people using image recognition technology
Face positions 8 position of human eye, and infrared range finder detects the distance between human body and projection screen.To the control fortune of processor 1
It is dynamic that drive module 4 or projection screen 7 is followed to move, ensure stereo display module and human eye 8 relative to projection screen 7 in mirror-bit
It sets, ensures that viewing personnel can observe clearly image.
Stereo display module includes display module 2 and camera lens 6；Display module 2 and processor 1 connect, and the control of processor 1 is aobvious
Show that module 2 will need in the image projection to projection screen 7 presented, the picture that display module 2 generates is projected by camera lens 6
It goes.
Display module 2 and camera lens 6 can realize the adjusting of projector distance with relative motion, can be in different depth of field shadowgraphs
Depth of field scanning is realized, to realize 3D display in face.
The imaging of display module 2 uses LCD liquid crystal displays, DMD digital micro-mirrors or LCOS chip imaging mode, using such mode
Equipment cost is low, can show clear image.
Secondary light source 3 is that light source is obtained by light splitting in stereo display module, is the relevant of light source in stereo display module
Light source, two kinds of light can generate interference, and the picture that secondary light source 3 can send out display module 2 is modulated.
It is illustrated in figure 3 the imaging schematic diagram of this system, stereo display module forms a real image point in space certain point,
If not on the screen, this picture point can form a larger hot spot to the picture point on projection screen 7, secondary light source 3 is sent out at this time
The light gone out also directive projection screen 7 and is overlapped with the hot spot of projection screen 7 and generates interference, forms hologram, at this time 8 energy of human eye
Enough see that stereo display module projects the conjugate imaging points of picture point.Conjugate imaging points are by level-one it can be seen from imaging schematic diagram
What diffraction light was formed, as long as so solid can be seen in mirror position relative to projection screen and stereo display module in position of human eye
The picture point that display module is projected in any spatial point, so as to see complete 3D rendering.
Projection screen 7 is the screen of transparent material, when image is got to the back side of projection screen 7 by display module 2, human eye
8 can be in 7 front viewing image frame of projection screen.
Projection screen 7 has the function of Automatic-expanding, storage, and projection screen 7 can be with Automatic-expanding, when being stopped when use
7 automatic accomodation of projection screen, can save space.
After adopting the above technical scheme, when total system works, processor 1 controls stereo display module in projection screen 7
Upper projected picture, in the light projection to projection screen 7 of secondary light source 3, light and stereo display module that secondary light source 3 is sent out are sent out
Light generate interference, formed hologram, so as to watch 3D pictures, eye recognition module 5 that can position 8 position of human eye,
By 1 analyzing processing of processor, 1 controlled motion of processor follows drive module 4 to act, motion accompanying drive module 4 and solid
Display module or projection screen 7 connect, and control stereo display module and projection screen 7 moves, make human eye 8 and stereo display module
It is in mirror position relative to projection screen 7, guarantee personnel can receive clearly 3D pictures when moving.By controlling stereoscopic display
The projection depth of field of module（Namely the depth of field scans）It can realize the presentation of true 3D rendering.In addition, although the present invention's is auxiliary
It is that mode relevant in the same direction realizes the reconstruction of hologram, but a kind of this side is not limited to when actual implementation to help light source and projected light
Formula, for example, it is reversed relevant（I.e. projected light and secondary light source are projected from the both sides of screen respectively）It can also realize the reconstruction of hologram.
It, can also be by the way of being projected on 3 dimension media in order to realize the 3D display effect of bigger visible angle.Such as
Using the system of a stereo display module and three-dimensional scattering screen composition.At this point, the light source that stereo display module uses is not necessarily to
Coherent source, solid scattering screen can be such that light scatters, such as the transparent boxes full of vapor or smog.Work as solid
When the converging beam that display module is cast out is irradiated on vapor, under the scattering process of vapor, luminous point can be in office
What angle is observed.This scheme can greatly save cost, provide flexible 3D pictures.
Entirety projection system architecture of the present invention is simple, occupy little space, production cost is low, while can realize that bore hole is watched
The effect of 3D images.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
All any modification, equivalent and improvement etc., should all be included in the protection scope of the present invention made by within refreshing and principle.
