Description

The improvement of three-dimensional imaging
The present invention relates to form the method and apparatus of three-dimensional imaging.
Three-dimensional imaging is a term of having continued to use century more than one, in this period, has developed into the content with complicated implication.
These implications are converted to the imaging of specific type from the meaning of the general imaging degree of depth, and wherein some brings distinct notion.
For example, this term is used to describe the imaging degree of depth, need be from single view, and do not consider other viewpoint.
On the contrary, other imaging three-dimensional description wherein do not have space or depth perception to occur, but show different viewpoints.
For the purpose that illustrates and define, in whole instructions, all adopt " three-dimensional imaging " term, imaging is defined as:
" comprise at least two adjacent visual angles simultaneously, they show three apparent directions from the point that has sufficient distance with respect to convenience center or the line of centres in a relevant visual space; Do not occur simultaneously more than one resemble ".
Most of such three-dimensional imaging is a viewer, and shading mirror and glasses are realized.They comprise simple wood chip and glass plate that the last century adopts, for example " Holmes viewer " and helmet electronic shutter, and they are synchronized with film or TV, the change of the image frame width of cloth.
Above-mentioned these systems rely on usually and stop that the scene on the left side in the object enters right eye, and stop that the video on the right side, object center enters left eye.
The shortcoming of these devices comprises: must use or dress them; Restriction to the visual angle: it is inapplicable that indivedual visions are had an atopic user.
These problems hinder the application of the rapid expansion of three-dimensional imaging for a long time.
After adopting viewer, may the next most possible scheme that adopts be two sides convex array, as a kind of optics grid, their use is documented in the early history of three-dimensional imaging.
Three-dimensional its principle of work of grill designs scheme is similar to viewer.Substantially, the scene that grid is used to isolate the left side, object center is to left eye, and the scene of isolating the right side, object center equally is to right eye.
Main difference between grid and the viewer is, the position of different sight optometries.Grid is placed on the front of imaging usually, and viewer is worn, or is placed on the front of eye.
One makes grid design portrait particularly by report, and it is by the Denmark artist, and S.A.Bois-clair made in 1962.It is narrow, vertical that the drawing of being introduced presents a row, sees respectively for the observer and look the rectangular of two scenes, and each long narrow picture bar is separated by a vertical lath.
Be that in the common design that this embodied image was drawn bar and entered right eye on the left of this film separation scraper was covered, and coverage right side image picture bar enters left eye.This to the segmentations of two complementary portraits and separately, fine if practical operation gets, it can demonstrate three-dimensional grid theory in practicality.In addition, it has also shown the inherent limitation of simple grid.
The principal disadvantage of above-mentioned design is presented by grid self.It need block each fully soon less than the imaging of half, and it is visible just making imaging thus.Based on this, it is poor the situation that grid is placed on the focus place that the mass ratio of effect is looked in its sight.
Second shortcoming of simple three-dimensional trellis system is to lack optical homogeneity.Desire to see three-dimensional imaging completely, element is looked in each sight must be applicable to corresponding eyes.This just restriction resemble size and visual angle become very little, just around the center of resembling.
In fact, big, high-quality three-dimensional image can leniently be seen and to look in the angle for many observers, adopts simple static grid device not obtain.
Two sides convex lens arra is used in the not enough aspect that overcomes above-mentioned first grid and has substantial improvement, looks although it only is used for little image sight usually.This improvement approaches by with transparent, and vertical lens fillet substitutes the solids barrier section and realizes.These lens are angled, and when right side scene was on the focus of right eye, left side video was on the focus of left eye.
Most of glass grid is invisible, because it is transparent, so the edge of lens fillet junction is opaque.
These edges and junction can make resemble smudgy, they also can introduce other undesired effect, comprise the spectrum aberration.
In addition, the restriction of all simple three-dimensional trellis system with other is still worked.
A further local improvement can be obtained from the dynamic barrier system of a kind of being called " in transferring stereoscope ".
Here, described grid can make it rotate around seeing screen with enough speed by rotating it, makes eyes cannot see screen, makes grid removal from sight is looked fully with this.This improvement is by French Patent (FRP) instructions No607, and 961 (Francoise Savoye proposes in 1942.10.8).
This design provides one effectively with solution to the grid visibility problems.As two-sided convex array, in transferring stereoscope to introduce new drawback, it does not solve the other characteristic in the simple grid design.Also have, described improvement is confined to little image, and the 3-D effect of part occurs.
The mechanical constraint that tunes stereoscope is overcome by the improvement that international patent specification No.PCT/AU92/00199 and Australian patent specification No.PL6295 are introduced.
These improvement provide to wear and hide eyepiece or the similar three-dimensional imaging that just can look with the sight of wide visual angle of individual different sighting eye mirrors.
According to an aspect of the present invention, provide a grid device that is used for three-dimensional imaging, comprise that wherein said slat is the lateral separation each other, has certain width and depth dimensions by the formed grid of many intervals slat between viewer and the described imaging; Spacing between its described slat of described grid device is tapered.
Need know that in form of ownership of the present invention, grid device of the present invention can separate, or being combined into a suitable screen apparatus, perhaps another kind of mode can be programmed, become a required computer packages, perhaps provide the grid of obtaining the object of the invention by sequencing.In addition, any suitable public machinery, electricity or the liquid crystal means also can be used for forming creative grid device of the present invention.
The present invention will adopt by way of example, and be described in conjunction with the accompanying drawings, wherein:

Figure 11 represents another kind of device of the present invention.
Figure 12 represents another kind of device of the present invention, especially a kind of situation of total optical-mechanical system.
Figure 13 represents the device according to another kind of form of the present invention.
The present invention has proposed many improvement to three-dimensional imaging, and these improvement are by mobile grating before the imaging that contains the adjacent visual angle of recognizable dislocation is produced.
Best, adjacent visual angle alternately is presented on separately the section, and in the time that human eye is not enough to perceive fast moving.
Best, discrete, the moving of image section that replaces carried out synchronously with the Movable grid element basically.This grating element preferably has certain shape, and section and position are all can represent the situation of each element and imaging from any sight apparent place.
The visual angle that the left side, object center is looked in adjacent sight only represents observer's left eye, and almost at the same time, all imaging that obtained by the right side, object center only represent the right eye in the observer.
The present invention allows from a wide angle, without viewer, sees the area of looking that resembles and sees three-dimensional imaging without restriction.
The present invention also allows from any distance, and without viewer, the area that resembles that sight is looked is seen three-dimensional imaging with being restricted.
The present invention allows each unit of the imaging of the left side by the object center being obtained from any desirable sight apparent place and direction to see to look, so that imaging represents the left eye to the observer continuously and fully, and the while is covered each unit of object center left side imaging continuously and fully and direction observed person's right eye sight is looked.Almost be simultaneously, each imaging unit that is obtained by the right side at object center and direction are represented the right eye to the observer.Meanwhile, each unit and the orientation of the right side imaging of object center are continuous again, fully cover observer's left eye.
The present invention also provides, and can make to see to look difference to resemble required minimal visual angle be changeable.This change is not restricted the possible ultimate range in object range of a signal place, to obtain best 3-D effect.In addition, the change that is provided can not limit obtainable imaging region and represent in arbitrary eyes.
The present invention also provides, and shows the vertical 3-D effect and the 3-D effect of level without restriction.
The present invention also provides, and the focal plane in the imaging is in the focal position simultaneously.If needs are arranged in addition, the focal plane can be without restriction in conjunction with the focused condition change.
The present invention also provides a kind of improvement, promptly allows the seamless apparent combination of each independent elephant, no matter be to three-dimensional or two-dimensional image all passable.This improvement allows the imaging of (as, wide, big, crooked or specific screen) of non-standard picture, increasing actuality, or produces other special-effect.
The shape of grid section and position to of the present invention successfully be important, below this will be further described and discuss.
As everyone knows, grid graph can be placed on the imaging front that comprises adjacent visual angle, to produce 3-D effect.
So far, these effects are restricted, and can not advantageously be applied to TV, and computer screen is in video display monitor central monitoring system and the many public imaging forms.
The many improvement that specifically have been used for three-dimensional trellis system comprise, adopt adaptive lens arra, common form with two sides convex lens, and dynamic barrier device.
There is not a kind of requirement that common imaging system is used of satisfying in above-mentioned two kinds of schemes.
Under the situation of using lens, two sides convex lens arra, a main shortcoming is a focus sensitivity, and it makes to see and looks near the little radian scope that is confined in the object.Actual application requirements is the unusual big display screen many with cost, also can provide enough sight visual angles to even little spectators.
To tune the stereoscope system be impassable shortcoming to being similar to have the inertial force of mechanical grille system of conditional electronic display screen and other main incompatibility.
The improvement that is proposed in international monopoly and instructions No.PCT/AU92/00199 and Australian patent specification No.PL6295 can overcome or reduce above-mentioned some obstacle at least.
This improvement makes the three-dimensional imaging can be from a wide radian, and the big distance relevant with resembling size seen and looked.
Equally, these improvement itself also help having the beholder of ordinary person's sensory features.
For example, the habit that human eye focuses in the imaging tends to increase his sensory property, and does not mind what the caused defective of grid is in face of it.
Can reserve part the memory capability of eye impressions, the additivity of accumulation identification if it is local or successively, all will help to feel by the trellis system imaging.
The human eye movement helps the horizontal scanning essential to this grill designs substantially equally, normally.
The improvement that in international patent specification No.PCT/AU92/00199 and Australian patent specification PL6295, proposes, and observe natural tolerance limit and the compensating action of looking in conjunction with the people, a kind of system quite flexibly will be provided.This system can be very satisfactorily, the optimization work of unusual ground.
These optimized work have determined the quality of three-dimensional imaging.Equally, they determine the size of elephant, and the apparent distance is seen at the visual angle, uses, and spectators how much, with the scope of human eye vision and common equipment.
For realizing purpose of the present invention, these technology optimum values are applied in:
I) imaging on the left side, all objects center is may be obtained by the imaging that the right side at the object center of any object range of a signal obtains from all when the angle of divergence of maximum,
Ii) the imaging of the left side, all objects center acquisition has only left eye, see fully, and the imaging on the right side, all objects center has only right eye to see fully.
Should understand that these criterions are not suitable for simple static grid.So, a kind of improved dynamic barrier device is provided, it is for obtaining desired standard and further feature of the present invention is essential.
In the accompanying drawing that this paper quoted, adopt following symbol:
L left eye position,
R right eye position

Fig. 1 represents a kind of simple, static mounting for grating.
Left eye position L and right eye position R are spaced apart, and typical interocular distance is 21/2 inch.
Eye position L and R towards display screen AB, shield widely 15 inches, and sighting distance e is 30 inches, is positioned at c, c1, c2, c3, the grill portion at c4 and c5 place from position L and R to resembling part a1, b1, a2, b2, a3, b3, a4, b4, a5, b5, a6 and b6 separate certain sight and look radian.
Look to be limited to fully from the sight of right eye position R and resemble part a1, a2, a3, a4, a5 and a6.
Look to be limited to fully from the sight of left eye position L and resemble part b1, b2, b3, b4, b5 and b6.
Grill portion, separately and carry out looking separately from position L to the sight of position L, grill portion simultaneously, separately and carry out looking separately from position R to the sight of position R.
The width of grill portion and position allow non-strictly from position L sight video part a1, a2, a3, a4, a5 and a6.
Equally, the width of grill portion and position allow non-strictly from position R sight video part b1, b2, b3, b4, b5 and b6.
This device shows that conclusion of the business is replaced, and imaging vertical and that the fillet mode is separated is applicable to from two positions to be carried out looking with the sight that separates fully, to any imaging total area partly without limits.
Can see grill portion for this simple static optical devices and be positioned at the focal position.
Can be width less than c, c1, c2, c3, the grill portion of c4 and c5 place width is placed on the bigger distance of imaging on display screen AB, and its effect is equal to those grill portion that is positioned at position c1-c5 place.
A width surpasses 15 inches, and seeing sighting distance is that 30 inches resemble can be used as data and the word processing that the video display monitor central monitoring system advances usually, yet display screen may be arbitrary width, can distinguish imaging in arbitrary distance of visual range.
So, as seen see under the constraint of looking normal, the display screen of any width can be placed on a certain position, and the grill portion that can place correct width in this position is to look with a left side and the right eye sight of the alternately imaging part that separately waits width and area independently fully.
Equally, can settle display screen leaving any distance that can discern imaging and angle place, the grill portion of correct width is placed to see with the left side of the alternately imaging part that separately waits width and area fully and independently and right eye and looks.
Fig. 2 shows, is suitable for the condition of this simple static grid device type.
Fig. 2 (I) representation class in varing proportions is similar to the device of Fig. 1.Among the figure, a left side and right eye position L, R resemble part a1, b1, a2, b2 on the display screen AB; Shield widely 25 inches, seeing sighting distance e is 5 feet.This situation is that the sight of typical home TV is looked.
Fig. 2 (II) representation class is similar to the device of Fig. 2 (I), and its difference is to have sizable sight apparent distance.Among the figure, a left side and the surface of position of right eye resemble part a3, b3, a4 and b4 on display screen CD; Shield widely 25 inches, see these 10 feet of apparent distance e1.
Fig. 2 (III) representation class is similar to the device of Fig. 2 (I), and difference is to have much bigger watching angle.Among the figure, a left side and the position L of right eye, R resemble part a5 on the display screen EF, b5, a6, b6, shield wide 25 inches, 45 ° at visual angle.
Fig. 2 (IV) representation class is similar to the device of Fig. 2 (I), and difference is to have bigger display screen width.Among the figure, a left side and right eye position L and R resemble part a7, b7, a8, b8 on the 60 inches wide display screen GH.
A kind of like this device can be used for the tv display screen of a high definition.
Can see that in all these examples grill portion can be placed on to make and alternately resemble part fully and a position that equally corresponding eyes is separated, what each eye was just seen it fully and equally resembles part accordingly.
So as seen these conditions are seen the apparent distance and visual angle applicable to all sizes that resembles.
Fig. 3 represents the expansion of Fig. 1 and 2 condition.Among the figure, the grill portion that is positioned at c and c1 place only is from resembling part a, b, and the sight that the part that carry out the left side of a1 and b1 and right eye position separates is looked.Different therewith is that the grill portion that is positioned at c2 and c3 place is fully separately looked from the sight of a left side and right eye L and R.
Fig. 4 represents that separately the width that resembles part on a left side and right eye is big more, is used for equating fully, separately and see the grill portion of looking separately by corresponding eyes apart the distance of display screen is big more.
Fig. 5 represents that the very little part that resembles can be equated and fully separates, and complete with corresponding eyes, and separately and individually sight is looked, and condition is that grill portion is close, or the very close part that resembles.
Among the figure, eye position L and R see video part a1, b1, and a2, and 0.6 inch is wide, and seeing apparent distance e1 is 9 feet.As seen, grill portion c, its position of c1 and c2 may be quite close, or almost with display screen AB on resemble part a1, b1 and a2 coincide.
Being positioned at sight apparent distance e1 is 4.5 feet, to the visual angle of display screen AB 45 ° eye position L and R, basically need identical grill portion position, be used for separately and get rid of to corresponding to a left side and right eye position L and R resemble part a1, the left side of b1 and a2 and right eye sight are looked.
Be positioned at and see apparent distance e2 on display screen AB, resembling part a, the eye position L and the R of b1 and a212 foot, a left side that requires the grill portion position separately to get rid of to resemble part and right eye are seen and are looked, and it is substantially the same in the part that resembles that is used for a left side and right eye position L and R that this resembles part.
So, as seen replace resemble the part be little position, can be placed on little grill portion very near the position that resembles the part front, provide distinct, and in wide visual angle and big horizon range, get rid of a left side and right eye is looked the sight partly that alternately resembles that separates with this.
In addition, it is more little to resemble part, to the requirement of grill portion and more little to the requirement of seeing the apparent place dirigibility.From device shown in Figure 5 as seen, this device is applicable to that one comprises that any sighting distance maybe can see any similar device at visual angle that resembles part.This shows, for the little and very little part that resembles, do not exist seeing the restriction of apparent place corresponding to little grill portion, promptly differentiate at human eye vision, fully separately and in the exclusive scope, provide corresponding to a left side that replaces the imaging part and right eye sight and look, and each eye is only seen half that all resembles part in this case.
Eyes grill portion can be placed on the front of any even imaging, so that can be seen the part that resembles of complete and exclusive equal number.
Can also place little grill portion near imaging, so that eyes are seen the part that resembles of number such as complete and exclusive from wide angle and different sighting distances.
Essence to all these devices is, the width that resembles part is identical with area, and the width of grill portion also is identical with area.
This requirement is inconsistent with the application that is used for the simple static grid of three-dimensional imaging.The displacement of corresponding vision element comprises adjacently under the visual angle situation of convenience center resembling, and increases from the center of resembling.
Fig. 6 represents that two resemble, and around convenience center adjacent visual angle is arranged, and have equal altitudes and etc. width, these two resemble and are presented on the screen.IL is the imaging that the left side obtained at object center, and IR is the imaging that the right side obtained at object center.
In any a kind of like this device, vertically resemble geometric center lines c, c1, c2 and c3 can adjust with being overlapped.
With vertical center line c and c1, overlap to adjust c2 and c3, all unit that resemble depart from how much and vertically resemble the center, and it will resemble according to two, resembles the unit and leaves the distance of center line and disperse from the divergence between the direction at common object center to the center of resembling.
In Fig. 6, e is the unit that resembles that resembles IL, and it is resembling of the left side, object center acquisition.
Resemble unit e and resemble vertical centre c, between the c1 apart from d greater than resembling unit e1 and resemble vertical centre c2, between the c3 apart from d1.
Equally, apart from d3 greater than d2.
Equally, the distance that rises apart from d2 and d3 is greater than distance d and d1.
So, as seen comprise around the corresponding unit that resembles of the imaging at the adjacent visual angle of convenience center and can not overlap more than a position adjustment.The deviation that non-adjustment point overlaps will increase from the center of elephant, and increase along with the increase of the divergence between the center of resembling.
To this, as seen can not be placed on the front that has the alternately imaging part of two adjacent angular around convenience center to the grid of equal wide, so that grill portion is separately looked by the sight to left eye that the left side obtained at object center, and looked by the sight to right eye that the right side obtained at object center.In each case, all parts that resemble can be seen by corresponding eyes fully.
Obviously, under the situation of simple static grid, the grill portion of placing unequal length is possible, so that contain by what the left side in the object obtained and resemble part and can fully and see by left eye exclusively, and comprise by the right side in the object obtain resemble part can be fully with see by right eye exclusively.
Yet only see apparent place as seen be to above-mentioned device from one, thus this device can not provide from any position required exclusive and completely separately sight look.
Fig. 7 represents that another kind can not be applied in the imaging situation that contains the adjacent visual angle of distinguishable difference to simple static grid.
If grill portion is to wait width, be placed on and contain adjacent visual angle, by the wide front of dispersing the imaging of place acquisition of distance convenience center, see when will cause watching about each eye and look.
In Fig. 7, grill portion C is resembling between part a1 and the b2, and it separates a left side and right eye position L and R fully and exclusively, resembles part a1 and a2 corresponding to L, resembles part b1 corresponding to R.
Resemble unit e1 and appear at and resemble in the part a1, L sees by the left eye position, it in resembling part b1 neither one accordingly by the appreciable unit that resembles of right eye.
Resemble unit e1 and e2 and appear at and resemble in the part a1, because e2 leaves the distance of center line c is left center line greater than e1 distance.This is a kind of example that typically is referred to as meaning " two imaging " in the partial 3-D imaging device.
Following improvement overcomes those above-mentioned restrictions.
Below other improvement of known technology can be applied in conjunction with each indivedual improvement the according to the requirement of final optics and three-dimensional quality.
At first be that vertical dimensions is used for the dynamic barrier part.
The dislocation grill portion is in the front of the alternately imaging part that contains the adjacent visual angle of visual difference.Make along the blocking effect equalization of each grill portion of light path.If the speed that moves is enough to make eyes can't see, then grill portion disappears, and produces a considerable imaging of looking, the summation of this imaging average blocking effect that to be each grill portion advance along its light path.
The placement grid is close, or very near resembling part, approximately can see grid until eyes, produces the effect of vertical depth or dimension in grid, and until the degree that produces a kind of " tunnel sight " (" tunnel view).This placement can improve grill unit and accurately a left side and the right side be resembled and partly separately proceed to corresponding eyes.
When utilization reduces distance that grid leaves display screen and improves situation that right and left eyes separates and be restricted, can increase the usefulness of grid so by the physical depth that increases grid.
When increasing the physical dimension of each grill portion, can utilize from outwards that stretch and in the imaging direction the vertical component of eye.Produce a kind of " tunnel is seen and looked " effect between any two grill portion, it can be looked each sight that resembles part and be separated into corresponding eyes fully, proposes sufficiently long vertical stretching simultaneously.
Fig. 8 represents two parts of grill unit G1 and G2, and the vertical cell that they comprised stretches to display screen from the observer, and G1 is than the more close display screen of G2.
As seen in Fig., the grill portion G2 of vertical stretching make a left side and the left side of right eye and right see to look fully exclusively separate, G1 does not do vertical stretching at this moment.
The degree of depth of grill portion and width can come fixed its size according to width that resembles part and grid apart from the needed position of display screen.
If grill portion is the identical degree of depth and width, and as width that resembles part and height, the grill portion that then contains vertical depth can be placed on from resembling part to any distance that resembles part fully, and be separated into corresponding eyes resembling part, as long as grill portion has the suitable degree of depth and width.
Can partly have the grill portion of appropriate depth and width by object placement, make to resemble the eyes that fully separately enter to separately to produce three-dimensional imaging, the part that resembles of this moment has the adjacent visual angle of recognizable difference.
Grill unit synchronously moves with resembling part, will produce three dimensional image, if wherein the speed of Yi Donging is sufficiently fast, then grill portion can not be seen.
When increase is used to produce the dynamic barrier part vertical depth of three-dimensional imaging, will reduce to see the visual angle of imaging, be shaped unless contain the grill portion of vertical depth, reduce the visual angle with this.
Fig. 9 represents to have a device of vertical depth grill portion, and it has shape, the wide sight visual angle of permission of band tapering.The shape of this band tapering can be equilateral, also can be the triangle of isosceles, and its size depends on required visual angle, resembles and resembles the size of part and see the distance of looking.
Can select the grille-like of easy adjusting for use for different situations.
The edge surface that makes the band taper simultaneously is to the observer, and the grill portion with vertical depth can be with tapering in other direction.For example, if when display screen is bending.Equally, grill portion can be oval, substitutes the shape or the diamond shape of band edge, and this will depend on the needs according to sight.
Figure 10 represents any one position to grid, and each one that resembles part all can not see; Cause the topographical view of imaging to be looked.When this situation especially appears at grill portion and has vertical depth.
A kind ofly each is resembled seeing fully of part look a kind of acquisition that to adopt in following two kinds of methods.
First kind, make grill portion equal at least along length to move on the continuous path of horizontal width of each grill portion, all grill portion are to wait width.This moving can be continuous in a direction, or oscillatorily carries out.
Second kind, along with the fixed position, for example the variation between the position that forms on a kind of electric light shows comes the Movable grid part, the noninertia device of described demonstration such as a kind of display panels or a kind of dynamic raster of similar formation.
Under second kind of situation, grill portion moves between point of fixity, key is, make mobile distance be equivalent to the width of grill portion, and in total moving range, the single motion of each grill portion resembles the wideest section the length that maximum angle required viewpoint in center is seen the imaging of looking less than be blocked in any position by grid from leaving.
May comprise any mobile minute step number finishing whole mobile routes in grill portion is limited by the regeneration rate in per step, therefore another kind of mode is the velocity variations grid position that can not see with a kind of observer, or with a kind of ratio that fixedly increases or descend, change the grill portion width according to the motion number in the whole cycle, as shown in figure 11.
Among the figure, the shape of grid or position change in whole moving period, and the alternately imaging part in the grid back must change simultaneously in identical mode.
Figure 12 represents a kind of situation of total optical-mechanical system, and wherein fixed view has position L and R, because it fixes, so the just part that can see at this point, or imaging is looked in the sight of sequence.
In moving period, Movable grid is partly by a point of fixity, the position between the position of an eye or two for example, and looking from the sight of this position so to be constant.This left side or right sight that just may cause only can seeing from that position is looked, and perhaps a left side successively and right the sight are looked, and perhaps can't see the zone of imaging.
A scheme that addresses this problem is to adopt a grid device is provided, its grill portion and horizontal line angle at 45, make imaging partly alternately before the grill portion of mobile definite shape and angle, and move with the sightless speed synchronization of eyes, produce the imaging of vertical simultaneously and horizontal scanning and vibration with this.This device comprises the vertical scanning imaging, allows to produce to comprise level and the vertical three-dimensional imaging that separates simultaneously.
Figure 13 represents a kind of device, and any two eyes are seen from any position and looked the left side that all can comprise left eye simultaneously and see and look and the right side of right eye is seen and looked, and can not cause or make eye to be limited to topographical view and look, and perhaps see successively and look.
In all situations, described those regulations can provide by being placed on the trellis system that comprises the imaging front that can distinguish different adjacent visual angles, and wherein grid is to be enough to that the sightless speed of eyes is moved.
In addition, can be used for the stratiform display screen to trellis system, at this moment, resemble part in an alternating manner or the function of while method execution grid and imaging.
Integrate, these devices provide the three-dimensional imaging with maximum angle of divergence that is suitable for any requirement distance to show by making up feature of the present invention.It comprises:
1. Movable grid part, promptly mobile phase contains the alternately imaging at the adjacent visual angle of obvious difference to total center synchronously, and all grill portion are to move with the invisible speed of a kind of eyes.
2. grill portion should be placed near resembling part close or very much, perhaps has vertical depth, and described grill portion is enough to make two visual angles separately to proceed to corresponding eyes fully and exclusively.
3. grill portion is taper, provides maximum visual angle in any direction.
Grid and resemble the part in moving process its shape or position change, in any one complete cycle grid or resemble the part the position do not repeat.
5. grill portion provides vertical and horizontal scanning with 45 to imaging simultaneously, or alternately imaging, and occurs 45 ° and alternately resemble part.
6. grid partly always keeps corresponding equal area with resembling on display screen, and is of similar shape when constant translational speed.
Real object does not have focus: normal sight is looked and is comprised that human eye focuses on by changing the position continuously.
This regulation can be used in the three-dimensional imaging, and this is illustrated by following method.
By changing focal length, in total scope of imaging from the object of the most close sampled point to changing focal length in the distance range away from the object of sampled point.Focus changes with the variation of Guan Huaxian with can connecting will, perhaps has one to put fixed change, and a change in any desired mode is perhaps arranged.
Producing certain imaging artificially and not being from the occasion of actual life record, can put and focus the plane, perhaps change the focal plane continuously according to required result.
Obviously, whenever should keep identical size by the adjacent visual angle that imaging comprised, the object in imaging is even also keep identical size in different focal positions.
In fact, these effects can the focal length by making camera lens automatically change change with picture and produce, in recording process before the camera lens and then scan by the visual field.
Out of phasely on display screen be combined with many difficulties, these difficulties are caused by the target edges non-uniform illumination that mainly it is always very obvious that these resemble the edge, in fact can not block to see and look.
In comprising the device of trellis system, trellis system is positioned at before the imaging, and will guarantee always to make and resemble the front that the edge is positioned at the grid position, is invisible at described edge, this position.
Should understand, among the present invention any type of machinery and/or electricity and/or electronically all can use, or be used to implement the present invention.Especially, grid device of the present invention can be by any machinery, electricity, electronics or other means realize.For example, mechanical system, the mode of electricity, the LCDs mode, or the computing machine producing method, as providing trellis system (for example display screen or tv display screen) with computer program in seeing screen, seeing between the imaging looked and the observer in desire with this provides a good grid device.
Need know, can make various improvement and change, as long as they do not depart from by claims institute restricted portion and just can the present invention.
