【Embodiment】
Present disclosure is further described below by instantiation.
Deformable Volumetric hologram implementation method, comprises the following steps：
(1) line holographic projections or objective image shown by display device current display interface, are obtained as actual image, is obtained
Observer is taken relative to the subjective image visually recognized shown by line holographic projections or display device current display interface
For hologram；
(2) amplitude that actual image needs to be elongated, is calculated：
A, as shown in figure 3, setting actual image is projeced on horizontal plane, as shown in figure 4, hologram is relative to level
Vertical 90 ° of the actual image in face gets up vertically；
B, the amplitude of elongation is calculated, first to set the eye level of hologram as H, it is as shown in Figure 5 and Figure 6, described
Visual ranges of the eye level H of hologram without departing from observer；Wherein, the eye level H of hologram and actual image
Length be relative, in other words, also first can preset the length of actual image and draw the eye level of hologram；
C, as shown in fig. 6, the distance for determining observer and hologram is D；
D, as shown in fig. 6, the height for determining the actual image of observer's eye distance is Y；
E, as shown in fig. 6, the length for determining actual image is X；
F, the numerical value for assuming D, H and Y is default detectable, and actual shadow can be calculated than formula according to the grade of triangle
As the numerical value corresponding to length x, i.e., the length of stretching required for actual image；
For example, observer and the distance D of hologram are 2 meters, the eye level H of hologram is from display plane (as
Face) 90 degree vertically hold up, and eye level H is 1 meter, and estimation observer's eye distance display plane (such as ground) is about 1.7 meters,
That is the height Y of the actual image of observer's eye distance is 1.7 meters.
As shown in fig. 7, A=2.625
∵ tan (a)=1.7/2
∴ a=40.365 °
B=180 °-a=180 ° -40.365 °=139.635 °
C=90 °-a=90 ° -40.365 °=49.635 °
∵ tan (d)=sin (c) ÷ (A-cos (c))=sin (49.635 °) ÷ (2.625-cos (49.635 °))
∴ d=21.073 °
E=180 °-b-d=19.292 °
∵ tan (e)=tan (19.292 °)=1 ÷ X
∴ X=2.857
1 meter of high hologram is formed in this embodiment, and the length of actual image is 2.857 meters.
(3) proportion of deformation of actual image nearby and faraway, is adjusted：
A, actual image is after elongation, as shown in figure 8, making up the angle formed by observer and actual image, and makes
The eye level H of hologram is corresponding to be changed, and causes the part that actual image is nearer with respect to observer, i.e., visual effect nearby
Upper meeting is larger；Cause the part of actual image with respect to observer farther out simultaneously, i.e., can be smaller in the visual effect of distant place, actual shadow
The nearby and faraway of picture is with respect to observer due to producing the distortion in visual effect apart from upper difference；
As shown in Figure 9, it is necessary to actual deformation of image, make up because image different piece and observer have different distance, and
Cause the deformation of visual image；For example, part drawing of the image apart from observer farther out is wealthy, that is, amplify；
B, the proportion of deformation needed for actual image nearby and faraway is calculated, its proportion of deformation formula is：
R=Lmin÷Lmax,
R is the most nearby size proportion of deformation with farthest, L on actual video visionminFor observer and actual image most
Distance nearby, LmaxFor observer and the distance of actual image farthest；
C, need actual deformation of image, by image processing software, adjust actual image farthest and be arranged to actual shadow
As R times most nearby, for making up different piece of the actual image due to its nearby and faraway with observer apart from upper difference
And cause visual deformation；
As shown in Figure 10, it is assumed that image is most nearby from observer's distance LminFor 1 meter, image farthest from observer with a distance from
LmaxFor 2 meters, Lmin=1, Lmax=2, so R=0.5；So the vision size (width) of actual image most nearby is relative " actual
Vision size (width) ratio of image " farthest is exactly 2: 1, so actual deformation of image need to be made actual image farthest
It is set as 2 times of actual image most nearby.
(4) difference of the actual image of right and left eyes, is adjusted
A, by the calculating and processing of step (2) and (3), actual deformation of image, make up because of actual image and observation
Visual deformation of image caused by the angle and distance that person is formed；But because observer can handle shadow through an eyes and brain
Picture, distance of the image with respect to eyeball is told, as shown in figure 11, and analyse that broken image is non-real erects；Last need to be passed through
The image processing of step, the brain of observer is cheated, it is takeed for image, most nearby relative observer's distance is phase with farthest
Deng i.e. hologram is upright if 90 degree, thus causes image to project the hologram in the eye of observer to erect；Tool
Body is, by 3D display equipment, the part of actual image farther out to be caused visually nearer or actual image is nearer than actual
Cause visually more remote than actual in part；Or actual image part farther out and nearer part are handled simultaneously, i.e., actual shadow
While causing visually nearer than reality as part farther out, also the nearer part of actual image is caused visually than reality
Far, make the left eye of observer and right eye that no image be respectively seen, so as to cheat the brain of observer, cause visual illusion shape
The distance most nearby with farthest eyeball relatively into actual image is equal visual effect.
As shown in figure 12, the adjustment amplitude of right and left eyes image, by distant place image part is pulled to how close determine or nearly
Place image part be pushed into how far to determine or simultaneously distant place image part be pulled to it is how close and will nearby image part point be pushed into how far
Together decide on.
Position and the distance that observer produces place with respect to image is calculated or estimated in the present invention, is calculated or estimated, and
Image is carried out torsional deformation processing by result, causes visual artifacts；So-called torsional deformation processing, in fact just as shown in Figure 2
Deformation process relief painting (anamorphic illusion) principle.But (and in non-photo) under practical circumstances, because people
Class may determine that the distance of image at the moment with eyes；So the only image Jing Guo deformation process, is to cheat in reality
The brain of observer thinks that image is the effect towered or erect.Therefore, it is necessary to further calculate, image is reprocessed, make into
Enter observer left eye and right eye image it is otherwise varied, produce the holographic visual effect in scene.
Therefore, by being calculated or estimated, image or anamorphose processing, then coordinate some 3D display devices, such as scheme
Shown in 13, can of the present invention produces the three-dimensional illusion of (holography) of towering in environment at the scene；It can horizontal plane, tiltedly
(surface that image is shown) is applied on the surface in face, curved surface or any angle；Vision imaging (artefact) can stretch out or go deep into shadow
Surface as shown in, and the vision imaging (hologram) erect can adjust the angle of setting on demand, that is, be not required to be defined to hang down
0 ° of Helicopter-9；And it can be that plane, solid are shone firmly to be used to make the raw video about stereopsis, or plane, 3-D cartoon,
Or plane, three-dimensional video video；And the 3D images through processing are also exportable into hard photograph, animation or video.The present invention's
Using the 3D visual experiences of observer can be expanded, while it can apply to the environment different with traditional 3D stereoscopic approach and application
On face.
It is exactly the example and principle of the present invention above, it is necessary to, it is emphasized that the calculating of the above is model in actual applications
Example, calculation and processing mode can make corresponding adjustment in response to the change of different-effect needs or environmental factor；Example
Such as, when image be not show in a horizontal manner (such as inclined-plane) or hologram be not set 90 ° uprightly, image stands as computer 3D
Body image (on-plane surface image), hologram be absorbed in or the display media below horizontal plane in (and non-protruding) etc., we
It will be appropriately adjusted in calculating or processing；But calculate the original that implementation method of the present invention is all based on the basis of processing mode
