Description
Technical field
The present invention relates to computer image processing and optical lens imaging device, especially space multistory imaging and display technique.
Background technology
In real world, we obtain some fine distinction between two observed image of different information----respectively by two eyes when observing object, thereby handle the far and near degree of perception observing object through brain again.Our brain " is known " when an object to come soon when identical two, and when just visual field difference was very little, observing object was positioned at position far away; Observing object is positioned at nearer position when two visual field difference are very big, feels the existence of solid space therefrom.
Stereo-picture is from broadly being divided into the stereo-picture of two formula stereo-pictures and narrow sense.Two formula stereo-pictures are to utilize two to obtain different picture information respectively and comprehensively produce stereo perception by brain again.Utilize the mode of this two sight equation to be made mostly now for three-dimensional display and three-dimensional film known to everybody.But this two formula stereo-pictures can not reflect all information that are expressed thing fully, and can not accurately reflect the locus of the original, stereo-picture technology main flow in the future, should be can be in the space to reproduce the three-dimensional real image that is expressed thing fully, the stereo-picture of the narrow sense of our definition just.A simple example, the observer utilizes visual inspection this when image, changes toward the left side and just can see the face that is expressed the thing left side, just can see the face that is expressed the thing right side toward the right commentaries on classics, just has space visual impression longitudinally.
The stereo-picture of narrow sense comprises holographic technology (holography) and 3 D full-figure technique (integral photography) and other imaging techniques that formed by the two derivation.
The difference of holographic technology and common photograph is that the photosensitive material of the egative film of common photograph usefulness can only write down the amplitude (light intensity) of thing light wave, and can not write down phase place, so can only show the plan view image of object on egative film.And holographic technology is to utilize interference of light that the amplitude of thing light wave and phase place are noted simultaneously, utilizes diffraction of light to make it to reproduce again under certain condition, thereby obtains three-dimensional image.Though the stereo-picture that holographic technology obtained satisfies two parallax and spoke degree and relief relation, but the restriction of technology such as Stimulated Light and high-resolution recording film and price, make large scale, the wide visual field, and the hologram of reflection original color is quite difficult; Because Stimulated Light can not be shone the influence of human eye and human body movability (the requirement subject was static when hologram was taken) etc., human body can not directly be made hologram in addition; And the regeneration efficiency of position phase shape holograph is common below 20%, and amplitude shape hologram is below 10%, can not obtain high-level efficiency.
The initial notion of 3 D full-figure is the lenticular lens sheet that utilizes insect compound eye shape at film photographs 3-D view completely.Owing to need high-precision technology and high-resolution photo technology, do not noted at that time by the people.It is at the end of the sixties that this technology begins to study in the world, concrete grammar is a principle of utilizing optical imagery, the focus face of recording film and compound eye shape lenticular lens sheet is consistent, utilizes laser radiation to be recorded thing, on recording film, form small image corresponding to each lens.Its cost of manufacture is low than hologram, and can write down three-dimensional information completely, realization or the effect that can reach above hologram.But because recording medium uses is film, therefore has equally and can not make animation, and the film after the exposure can not reuse etc. problem to be solved is arranged.
Goal of the invention
Though holographic technology can be obtained stereo-picture true to nature, large scale, the wide visual field are made in the restriction of Stimulated Light and high-resolution recording film etc., and the hologram of reflection original color is but quite difficult.Though and original stereo-picture technology cost of manufacture is low than hologram, and can write down three-dimensional information completely, also have film and can not reuse weak points such as more can not making animation.This shows, reduce technical difficulty and production cost, realize simpler production and regeneration stereo-picture, reach and to reuse, can show on display that particularly the image of making to reach the effect of making the dynamic solid image, is current stereo-picture urgent problem.
The objective of the invention is to reduce technical difficulty and the production cost of making stereo-picture, the effect that other servicing units can with the naked eye observe directly the space image that is expressed object is realized in any place, be need not to the stereo-picture completely that exploitation has characteristics such as colour, animation, bias free.The another one purpose is to make the wide visual field, be not subjected to the size restrictions and the accurate stereo-picture of reflection body structure and locus, and utilize existing simple animation display device (as display, projector), the three-dimensional image information that only need import into after the processing can be seen dynamic stereo-picture.
Summary of the invention
The present invention copies the imaging mode of insect compound eye type convex lens (miniature hexagon convex lens) array, utilize special computer image processing and corresponding algorithm to replace original optical imagery mode, produce the position and the color (or gray scale) of each picture element in the X-Y scheme image planes, and then utilize compound eye type convex lens array that image is after treatment gathered the stereo-picture that becomes to be expressed object again in the space, and between distance observer and image display device, place the sharpness that a light scatter plate is used to increase stereo-picture.
The present invention to the design of the miniature convex lens array of ultraprecise and lens sizes (radius, focal length) to the work of the influence of image quantitative analysis, propose to generate the lens arra processing scheme of best stereo-picture.
The present invention can make stereo-picture with any stereoscopic image data.Former stereoscopic image data can adopt profile scanning figure that ct machine (CT) or nuclear magnetic resonance equipment (MRI) etc. obtain and any solid figure data that can be produced by computer image processing.In the present invention, utilize the space structure of the three-dimensional thing of computer graphics methods analyst, set up algorithm correspondingly, making can the distinct space multistory image that reflects the inner structure of former three-dimensional thing.Utilize the color digital photo in the space, to superpose in addition, made the anaglyphs with far and near stereovision that can compare favourably with former photo image quality as original stereoscopic image data.
The present invention has also done further research to the dynamic solid image that generates high definition simultaneously, utilize existing simple animation display device (as display, projector), the stereo image information that only need import into after machine is handled as calculated promptly can be made into vivid stereo-picture.
The invention effect
The present invention can develop the stereo-picture completely of characteristics such as having authentic color, animation, bias free, realize in any place, need not other devices (for example special glasses) with the naked eye (simple eye getting final product) observe the effect of the space image of former indicated object thing, and can not produce any visual fatigue to naked eyes.Feature of the present invention is to utilize the computer picture technical finesse to obtain observed image, only needs to change observed image and can reach recycling effect.Maximum characteristics of this effect are that only need be imported machine processing back continuous images information as calculated in existing simple animation display device (as display, projector), can see dynamic stereo-picture.
The present invention utilizes computing machine to make, represent stereo-picture because of from the geometric angle of space multistory, does not have the image shift problem that is produced by lens devices.Be in the record or the restriction that is not subjected to light wave of regeneration in addition, so reproduced picture can reappear the realistic colour that is expressed object exactly.
The present invention can be used in simpler production and the real stereo-picture of regenerating, and does not need the stereo-picture technology of other servicing units.The present invention can be widely used in following field: 1, support the stereo-picture prompting of operation usefulness in the medical field; 2, stereo-picture association area (for example: stereoscopic photograph, stereotelevision, binocular projector etc.); 3, stereoscopic teaching; 4, three-dimensional artwork etc.
Technical scheme and embodiment
The invention will be further described below in conjunction with drawings and Examples:
Fig. 1 is stereo-picture generating principle figure of the present invention.Fig. 2 is the stereo-picture presentation graphs of regenerating in the space.Among the figure, (1) compound eye type convex lens array, the image surface that (2) computer image treatment generates, (3) stereo-picture raw data, the regeneration stereo-picture that gathers in (4) space, (5) observer.
(1) selection of the design of convex lens array and stereoscopic image data
Because the design of compound eye type convex lens array and the selection of lens material will directly influence the quality of stereo-picture, at first we make technical descriptioon to the best design of the compound eye type convex lens arrays (1) that occur among Fig. 1 and Fig. 2 in Fig. 3.
The lens starting material are optional high and be processed into the material of optical lens easily with light penetration, and organic material or optical glass all can be used as the object of its selection.The present invention selects methacryl resin for use, be that (refractive index is 1.49 because methacryl resin has the superior transparency, good free processability and good features such as permanance, the light penetration directional light is 92%, light is 93% entirely, heat distortion temperature is 100 ℃), it also has characteristics such as light and handy, tough, corrosion-resistant and electrical isolation in addition.
Because the field of view of stereo-picture and the center of curvature (8) that effect is subjected to single miniature convex lens (7) are to the influence of the mutual relationship of distance (9) between the picture plane (2) and lens diameter (10).For the solid figure of same resolution, lens are long more to the distance between the picture plane (9), and the field of view scope is more little, and it is clear more to draw a portrait; Lens radius is big more, and the field of view scope is big more, and the portrait sharpness reduces.
Lens arra among the present invention adopts convex lens to arrange the convex lens array (6) that forms, and the purpose of this arrangement is to hold the miniature convex lens (7) of maximum number in same area.Miniature convex lens with a diameter 2.32mm are example, and (203 * 254mm) can arrange the micro lens (134 per square inch) about 10,000 on the lens arrangement face of an approximate A4 paper size.The processing key of lens is that the focal length (11) of the single miniature convex lens in the compound eye type lens arra (1) and the picture plane (2) that calculates generation are consistent.
Secondly, in Fig. 4, the stereoscopic image data among Fig. 1 (3) is described in more detail.(12) are the profile scanning image that nuclear magnetic resonance equipment (MRI) etc. is obtained among Fig. 4, and (13) are several the stereo datas that photo is superimposed as.
There are some kinds of approach in the stereoscopic image data source.Former stereoscopic image data can adopt the raw data (12) of the profile scanning figure that ct machine or nuclear magnetic resonance equipment etc. obtain, and any stereoscopic image data that can produce by computer picture (CG) treatment technology, these data both can be that the bitmap images that pixel constitutes also can be a vector graphics.Utilize medical profile scanning image, can obtain the image that the inside of human body and other real objects be can't see, adopt this approach the stereo-picture technology can be used for fully the association area of medical field and other diagnostic imagings.If only want to make the stereo-picture of different far and near levels, then can be superimposed as stereo data by different far and near photos (13).We utilize the color digital photo to superpose as original stereoscopic image data in the space, have made the anaglyphs with far and near stereovision that can compare favourably with former photo image quality.
(2) computing machine generates the algorithm and the stereo-picture renovation process of stereo-picture
The pre-treatment that more than is the stereo-picture imaging is prepared, and below in conjunction with Fig. 1 stereo-picture generating principle and Fig. 2 stereo-picture presentation graphs of regenerating in the space, concrete grammar of the present invention and ultimate principle is described further.
Usually when making stereo-picture, because observer's viewpoint and the homonymy that display surface is positioned at the object that is shown, the object that is expressed that just we see is the back that appears at display surface, therefore when imaging from from display surface nearest be expressed object begin carry out the back and handle.But, the thing that is expressed that stereo-picture is shown is the place ahead of appearing in one's mind at display, the homonymy that is positioned at the object that is shown from observer's viewpoint and display surface just, if utilize same back disposal route, the stereo-picture that is observed so becomes the picture (pseudomorphism) of concavo-convex counter-rotating.The algorithm of image processing of the present invention is according to the special imaging mode of stereo-picture, and the closest approach that begins from observer's viewpoint direction just begins farthest point from display and carries out the back and handle.Concrete grammar is laying down a definition in conjunction with Fig. 5, send at each picture element center (14) on the prolongation light (15) at pairing lens curvature center (8) by it, come on this picture element of projection with picture information, utilize the inner product of the surface normal direction of probing light direction vector and indicated object thing to calculate picture element color or the gray scale asked simultaneously from the crossing (17) of observing the initial and represented object (16) that side sees.The present invention utilizes this back Processing Algorithm, has not only finished the technical matters of having drawn but also solved the concavo-convex counter-rotating when record generates of original stereoscopic imaging method to three-dimensional thing structure.
Fig. 6 makes figure for calculating the gained stereo-picture, the one-piece construction figure of stereo-picture generation figure among the left figure of Fig. 6 is amplified to behind the single picture element among the right figure of Fig. 6 behind the image, in each hexagon (20), all comprised the projection of former three-dimensional shape as can be seen, that is to say in the hexagon scope of each miniature convex lens correspondence and writing down the Global Information that is expressed object.This Global Information is embodied in by on each picture element (21) that calculates the ganmma controller, shape and the spatial positional information that generate.The resolution that we can find to write down the picture plane that is expressed object is high more, just holds many more picture elements in same hexagon (20) scope, so just can critically write down the information that is expressed object more.
Fig. 2 is stereo-picture regeneration principle figure: stereoscopic images displayed on calculating face, then begin to launch the light of the scioptics center of curvature (8) and ray intersection fork that other pixel sends, just in time can see luminous point (19) at there from observer's side from each picture element (18).Constitute the object of expression in the space of the luminous point that gathers like this (19) before display, observer thereby can see the stereo-picture (4) that is gathered into regeneration.
(3) theoretical analysis of compound eye type convex lens optical imagery
Fig. 7 has represented the relation of light spot position and other parameters.At first reference field (22) is set on the face of the center of curvature (8) of each lens by compound eye type convex lens arrays (1).The diameter of miniature convex lens is D (10), and reference field (22) is h (23) to the distance of picture plane (2), and the size of single picture element is r (24), and i is for to begin to the distance at i picture element (25) center from the center.On the crossing of the light that sends from two adjacent lenses, the distance of note from reference field (22) i intersection point of beginning (26) to reference field is Hi (27), can obtain by the relation of similar triangles
In the picture element in the hexagon scope of single lens correspondence, the position, lens center begins to count the light that i picture element (25) sends, with the light of scioptics center in the adjacent lenses and corresponding center pixel point in i luminous point (26).Here the maximal value of i is i
Max=D/2r.Same and lens standoff distance are in the light (29) that sends of lens diameter j times j lens (28), begin to be designated as H to the distance of i crossing from reference field (22)
I/j(30), its expression formula
As can be seen in (A) formula irradiation less than the position, according to (B) formula may by the irradiate light of other lenses emission to.In addition by (B) Shi Kede, can be descried nearest luminous point be H to the distance of reference field
1/ i

Resolution to the space projection image performs an analysis below.
Luminous point as Fig. 8 (a) longitudinal projection's image that is shown in is a double cone shape by two oval awl be combined intos.H (31) is the distance of luminous point to reference field.The sectional drawing that can arrive in Fig. 8 (b) by central point is a quadrilateral (32).Note is 2 α (33) from the interior angle of observer's angle near point and far point, and 2 β (34) then arrive the luminous point longitudinal length R of reference field (22) distance for the H place
z(35), amplitude R
x(36) be
Under normal conditions, because lens diameter D (10) compares lessly with spot distance H (31), can see approx
R then
z(35) and R
x(36) relation can be expressed as
By formula (C) and formula (F) R as can be known
z(35) and R
x(36) all be directly proportional with distance to reference field.Because square being inversely proportional to of the brightness of luminous point and distance, the luminous point that is projected along with to reference field apart from increase and deepening fogs.
(4) stereo-picture regenerating unit and sharpening are handled
Fig. 9 is the static stereo-picture regenerating unit of high definition.From left to right arrangement is followed successively by and calculates picture plane (2), compound eye type convex lens arrays (1), the scatter plate (37) that generates among the figure.In fact we upward just can see stereo-picture as long as compound eye type convex lens arrays (1) are placed on the picture plane (2) that calculates generation, but owing to these stereo-pictures are to be formed by luminous point (38) combination that the light that each picture element on the picture plane sends can synthesize, these luminous points are dispersed after polymerization again, what therefore the image that forms in human eye became is smudgy, and this situation increases the weight of along with the increase of miniature convex lens diameter.In order to increase the sharpness of image, place a scatter plate (37) in the stereo-picture space that we gather before compound eye type convex lens array.Figure 10 is the comparison that has or not scatter plate.Observed result during (39) for no scatter plate, (40) observed result when scatter plate is arranged, after using scatter plate, because the light diffusion increases the light number that enters in observer's eye, the resolution image that is lower than the picture element of lens diameter also can clearly be seen like this.
Scatter plate can be selected frosted glass or film.When miniature convex lens diameter during, do not use scatter plate to can be observed image clearly less than 1mm yet.
(5) embodiment
According to above method, the present inventor uses the C++ coding, and the different qualities at the static dynamic stereo-picture of high definition makes different execute files and generates compound stereographic map image planes.
Embodiment 1: the static stereo-picture of high definition
The present inventor utilizes the computing machine of PentiumIII 500MHz internal memory 256M, generate an A4 paper size, image resolution 600dpi, pixel value is Raw form (24Bits/pixel) image file of 4320 * 5760 (pixel), need 10～15 minutes computing time, and the file size of generation is 72M.Be that the color laser printer of 600dpi is printed the image after machine is handled as calculated with resolution simultaneously.Why the present invention uses the Raw form to come storage data is in order to preserve all images information after machine is as calculated handled, to should be emphasized that and should not use the high compression form to store data.
Figure 11 is the observed from different perspectives effect of same static stereo-picture.The present inventor utilizes the method for Fig. 9 to make the stereo-picture sample.Fixed sample during shooting is taken while change the observation place, can find all to have for any one viewing angle the embodiment of corresponding with it movement vision difference.Five width of cloth figure among Figure 11 be respectively can be from the top the different outboard profiles of the same static stereo-picture that photographs of (41) below (42) left (43) right-hand (44) and positive (45) different angles, we can see that stereo-picture has strong whole continuity thus.
Embodiment 2: the dynamic solid image
Figure 12 is the dynamic solid image display device that utilizes LCD to make.Current liquid crystal display resolution is about 100-200dpi, on the screen of LCD (46), place compound eye type convex lens arrays (1), regulate scatter plate to the appropriate location, the three-dimensional image information that only need import after machine is handled as calculated can be seen dynamic stereo-picture.This dynamic solid image can look to being used to make in the future stereotelevision.
The high resolving power dynamic solid image display device of Figure 13 for utilizing projector (47) to make.Prices are rather stiff because the colour liquid crystal display device that liquid crystal display resolution is subjected to the restriction of the present art, resolution to be higher than 200dpi is made.In order to address this problem, consider to utilize projector as display device, by adjusting to projector (47) focal length, the high-resolution picture (can reach more than the 1000dpi in theory) that gathers is projected to screen (48) go up formation perspective view (49), improve the light penetration of scatter plate simultaneously, then can be made into the stereo-picture of high definition.This dynamic solid image can be used for making the stereo-picture film in the future.
