Description
Affiliated technical field
The present invention relates to the 3D stereo display technique scheme that a kind of suitable bore hole is watched, especially color by each pixel in the real-time modulation display matrix and image distance realize the 3D stereo display technique scheme to the real scene reduction.
Background technology
At present, known stereo display technique is common following several: 1, polarized light separates stereo display technique; 2, divide the field scan stereo display technique; 3, left and right sidesing shifting stereo display technique; 4, red green separates stereo display technique; 5, holograph stereo display technique; 6, grid skew stereo display technique; 7, prism skew stereo display technique.Wherein 1,2,3,4 all need wearing spectacles, and 5,6,7 do not need to wear glasses.To do the contrast explanation to above various realization technology below.
Preceding four kinds of technology all need to wear special eyeglasses, and wherein 1,2 two kind of display effect be better, 3 effect is medium, and 4 effect is relatively poor.But wearing anaglyph spectacles can make the beholder feel inconvenient on the one hand; On the other hand because it satisfies psychology and physiology depth of field hint (cue)---binocular parallax (binocular display) and convergence (convergence), thus cause and other depth of field hints, as the difference between adaptability and motion parallax.It is tired and dizzy that this species diversity will cause human body to produce, and is not suitable for watching for a long time, more is unfavorable for some crowds, watches as old man, child.Therefore the 3D of wearing spectacles demonstration is called as " ten minutes medium (ten minutes media) ".People need reduce restriction, 3D display technique more natural, more closeness to life mode.
The three kinds of technology in back do not need wearing spectacles, and wherein 5 effect is best, but structure extremely complicated, realize that cost is huge, data volume super large and be difficult to practicability.6 have seen and have been applied to stereo-liquid crystal display device, and effect is better, but narrow viewing angle, and stereoeffect is limited in narrower distance, the angular range, watches number and position to be subjected to a lot of restrictions.Be used for toy and less demanding still frame 7, picture quality is relatively poor more.
More than the described stereo display method of listed technology, exist or must wearing spectacles or effect is relatively poor or the problem that is difficult to realize, can not satisfy the needs of people's practical application.
Summary of the invention
In order to overcome the disadvantage that has stereo display technique now and to realize better display effect, the invention provides the 3D stereo display technique scheme that a kind of image distance by each pixel in the real-time modulation display matrix realizes the real scene reduction.
The technical solution adopted for the present invention to solve the technical problems is: by the dynamic color image of flat panel display device demonstration or projection, by dynamic focusing mixed light mirror matrix to the projection imaging of dynamically focusing of its image pixel unit, its each pixel cell is distinguished dynamically focusing, the real image image distance that is become also changes thereupon, adjust image and the distance of lens and the voltage or the electric current of focusing, make its image distance equal or be proportional to the image-forming range of the three-dimensional outdoor scene appropriate section in image Central Plains tight shot, the mixed light mirror other end will obtain different image distances by the pixel cell real image of mixed light, be big three-dimensional dynamic color real images such as and original image.These three-dimensional real image scioptics or the imaging of little shape lens matrix are watched, then formed three-dimensional display; Perhaps three-dimensional real image is projected to imaging on the video picture eyeglass once more,, then form stereo projection system to realize true reduction to stereo scene.Its light path principle is similar to the contrary principle of shooting, and specific explanations is as follows:
In shooting, three-dimensional outdoor scene is projected on the photoreceptor reading and writing down and just realized the shooting process by pick-up lens to photoreceptor.In common shooting process, adopted the camera lens of the big depth of field to satisfy the panorama sharpness of image, and recording light data only as far as possible, do not write down the range data of scene.
In the light path of the convex lens imaging of reality, the image distance of each some imaging is different in the three-dimensional outdoor scene, according to the light path principle of reversibility, if can be recovered to the color and the image distance of each pixel of image position, the words of back projection will be reproduced the color and the distance of former each part of scene.Therefore, if can obtain the image-forming range data of video file, then when image color reappears, the mode by real-time modulation focusing lens object distance realizes the reproduction to image-forming range, then can recover the imaging color and the imaging image distance of former three-dimensional outdoor scene.As mentioned above, by to its once more projection reproduce three-dimensional outdoor scene.
Dynamically focusing mixed light mirror be a kind of intensified image apart from and do not amplify area or area amplified very little lens set, can transfer to realize that large-scale image distance changes by small electricity, be called for short the mixed light mirror.The mixed light mirror comprises the lens of can dynamically focusing of front end or zoom and the cylindricality plano lens of rear end, and two lens axis overlap, for ease of describing, can dynamically focusing or the lens of zoom are called for short focusing lens, cylindricality plano lens abbreviation post mirror.Post mirror area of section is identical with the original image pixels cellar area, and the focusing lens area is smaller, so that motion.For two kinds of different original images, different focusing formation methods is arranged: to the plane picture that uses display device to show, can be with convex lens to its imaging of focusing; To the real image image that uses projection to produce, can be with convex lens or concavees lens to its imaging of focusing.This explanation will be analyzed with the scheme of using display device.Less than two times of focal lengths, focusing lens is imaged in the post mirror or passes the post mirror original image the distance of focusing lens and original image greater than focal length.In the post mirror during imaging, the light of wherein meeting post Jing Bi by the one or many total reflection after imaging in the cross section of post mirror, its image-forming range does not change, repeatedly the light of total reflection is realized mixed light at imaging plane, because original image is identical with the real image area that is become, therefore, the mixed light mirror has been realized the amplification to object distance, and does not amplify the area of original image.Mixed light mirror matrix is by transferring the small electricity of each focusing lens, and the real image pixel cell that is converged to respectively is combined into the three-dimensional real image of the big depth of field.If image-forming range exceeds the mixed light mirror, imaging area has certain amplification with respect to image distance, but owing to be subjected to the restriction of mixed light mirror tail end section area, the elemental area of imaging also only has faint variation in closer distance.In imaging, dynamically adjust the object distance of focusing lens, the image distance respective change of mixed light imaging then, its variable in distance rule meets the imaging formula of lens: 1/u+1/v=1/f.
Mixed light mirror matrix is to each pixel of a plane picture projection imaging of focusing respectively.Focusing lens do not have modulated in, image-forming range v=fu/ (u-f), on this plane, the original image pixels unit big real image such as is converged to and by mixed light.When adjusting object distance according to the content driven focusing lens of image, its corresponding real image image distance that pixel became will change before and after the quiescent imaging position, its imaging area equals post mirror cross section and equals former pixel cellar area, the light of imaging since repeatedly total reflection and when converging by mixed light.Adjust the control degree of focusing lens, the variation that makes this image distance corresponding to the actual imaging of original image content apart from the time, plane picture will be three-dimensional real image by mixed light mirror imaging.Change the distance of mixed light mirror and plane picture, real image can be positioned at outside mixed light mirror or the mirror.
When needs direct viewing solid real image, can use lens to three-dimensional real image imaging, as telescope or microscopical eyepiece principle, lens can adopt single or multiple combinations such as convex lens, concavees lens, Fresnel Lenses.For example adopt single big convex lens or the miniature convex lens matrix corresponding, adjust the distance of convex lens and mixed light mirror,, at this moment can see the virtual image that three-dimensional real image becomes by convex lens with bore hole to reach the sharpness of the dark scope maximum of panorama with the mixed light mirror.
If three-dimensional real image is further projected on the video picture eyeglass, allow three-dimensional real image between the focal length of projection lens and two times of focal lengths, allow the image distance after the reprojection change in the imaging scope of video picture eyeglass, then can on the video picture eyeglass, see stereo-picture with bore hole
Thisly each pixel of plane picture is focused respectively by the mixed light mirror, the other end at the mixed light mirror reproduces the color of former scape material object and the method for distance, can be used to make three-dimensional display and stereo projector in actual applications, perhaps other needs instrument, equipment, the system of stereo display.
This stereo imaging system by the bore hole direct viewing, the image-forming range in kind when the image-forming range of its three-dimensional real image can be equal to or be proportional to shooting, therefore the stereoeffect that produces is also near real scene.And its light path is made up of optical mirror slip fully, so the brightness and contrast is very high, is a kind of optimal imaging mode.
Principle of work is described with reference to the accompanying drawings:
One, system constitutes: with reference to Fig. 1, the mixed light mirror matrix of dynamically focusing is made up of four parts: 1, planar imaging device; 2, can distinguish the convex lens matrix of dynamically focusing or zoom; 3, cylindricality plano lens matrix; 4, storage and driving circuit.To illustrate respectively below.
Two, the structure of mixed light mirror and control principle: with reference to Fig. 2, Fig. 2 (a) (b) is to use display device and projection real image to produce the light path principle figure of plane picture as original image respectively.For two kinds of different original images, different focusing formation methods is arranged: to the plane picture that uses display device to show, can be with convex lens to its imaging of focusing, as Fig. 2 (a); To the real image image that uses projection to produce, can be with convex lens or concavees lens to its imaging of focusing, as Fig. 2 (b).This explanation will be analyzed with the scheme of using display device.Mixed light mirror matrix is the matrix that is combined into by a plurality of independently mixed light mirror assemblies, each mixed light mirror assembly comprises planar pixel (1), the lens that can dynamically focus or electric control zooming mirror (2), post mirror (3), storage and driving circuit section, and the object distance of each focusing lens (2) can dynamically be modulated separately.Do not have when modulated, focusing lens (2) projects into real image (4) fixed position in the cross section of post mirror (3) to planar pixel (1).When focusing lens is modulated by signal, the image distance of projection real image changes, with reference to Fig. 3, Fig. 3 is a kind of construction profile of the 3D three-dimensional display of being made by mixed light mirror matrix and LCD, the change in location of the corresponding focusing lens of the imaging image distance of a row mixed light mirror of being seen and difference is arranged, image distance increased when object distance diminished, object distance greater than focal length less than two times of focal lengths.Pixel cell to plane picture is focused respectively, image distance equaled or be proportional to the image-forming range of the relative tight shot of former three-dimensional outdoor scene, according to the light path principle of reversibility, this three-dimensional real image by tight shot once more projection will reproduce the color and the distance of former scape.Driving method to focusing lens has a lot, such as: electric field force modulation, electromagnetism modulation, thermal deformation modulation or the like, every technology of the little distortion of may command that can realize can both be used for greatly the object distance of focusing lens is modulated in real time.Also can adopt the electric control zooming mirror to realize modulation to image distance by zoom.Concrete structure and implementation method will illustrate respectively below.The modulating frequency of focusing lens is higher than the field-scanning period that video shows in the matrix, and existing above said modulation technique is all considerably beyond this parameter, and technical being easy to realized.
