Description
The present invention relates to Computer Applied Technology, the new method that especially a kind of stereotome is made.
The method of existing three-dimensional imaging is broadly divided into several big classes such as holographic photography method and parallax method three-dimensional imaging.Holographic photography is to adopt laser to make light source, record thing light wave and with reference to the interference pattern of light wave, go out the three-dimensional image of the original then with laser or white light reconstruction, this is a kind of upright monomer figure truly, but because photographic light sources, the harsh requirement of recording medium and other technology, process aspect, it is civilian to make that this technology does not really enter at present as yet.Figure is to the method three-dimensional imaging, because principle is simple, is easy to realize that cost is low to be to enter civilian main method at present.Early stage figure is the picture that has parallax with two to the method three-dimensional imaging, and " stereoscope " by a special use enters images of left and right eyes respectively with two figure and observe, and obtains stereo-picture; Developed " optical filter method " and " polarized light approach " afterwards again and observed stereo-picture, two figure that are about to scheme centering become different colours by filtering method, or become mutually perpendicular polarized illumination with polaroid, with having optical filter glasses or polarised light glasses observation figure right mutually, make two figure of figure centering enter images of left and right eyes respectively and obtain stereo-picture again.Above-mentioned figure will just can obtain having relief image by specific purpose tool to the method three-dimensional imaging, and both inconvenient, observing effect is also poor.
A few years ago, people utilize the Computer Design disparity map, adopt the method for " the eyes intersection is looked ", promptly so-called " bore hole " observation can obtain having relief image, and this method is except picture material has limitation, when seeing sheet, also need eyes are done special adjusting training, the eyes utmost point is unnatural when therefore observing picture, and some people just can't observe at all.
" column mirror grating method " and " slit grating method " Stereographing system had been developed in recent years again, be to belong to figure to another new method in the method three-dimensional imaging, basic skills is to adopt many stereo cameras machine single exposure or one-shot camera repeatedly to take by displacement, obtain having one group of egative film of parallax information, with of stereo enlarging print machine or enlarger on special grating printing paper the imaging of this group egative film through particular design, obtain having relief photo, also can imaging on the common photosensitive material, again through the compound stereoscopic photograph that obtains of grating.This stereoscopic imaging technology need adopt complicated optical system, precision optical machinery and computer controlled automatic etc., and therefore, equipment is expensive, and energy resource consumption is many, and floor area is big, and the photo flushing has chemical contamination etc.
The objective of the invention is deficiency, provide a kind of electronization to make the new method of stereotome, to overcome the many disadvantages of art methods at existing stereoscopic photograph technology.
For achieving the above object, solution of the present invention is: use a computer, image capture and Input/Output Device, adopt suitable Computer Image Processing method, make stereotome in conjunction with existing grating complex technique.
The present invention has broken away from the optical stereo formation method because of having adopted the computer technology construction drawing to answer print, have more flexible than optical means, characteristics more easily; Along with popularizing of home PC, function constantly strengthens, and the relevant input-output device ratio of performance to price improves constantly, constantly miniaturization, and the exploitation of image processing software is perfect etc., will make the inventive method make more and more high-quality of stereotome, cheapness, equipment is more and more lighter; Utilize the inventive method can also produce the artificial stereotome of fabricating, also can be used as stereoprojection, obtain having the large screen projection figure of parallax stereoeffect.Can be widely used in stereoscopic photograph, three-dimensional lamp box advertisement and stereotome decoration etc. for this reason.
Below in conjunction with accompanying drawing, the present invention is further detailed explanation.
Fig. 1 is the principle schematic of this bright method.
Fig. 2 is the Computer Image Processing process synoptic diagram of figure to answer print.
As shown in Figure 1, connect one or more camera heads 2 on the computing machine 1, be installed on the guide rail 3 as the camera head 2 of image capture and input equipment; One group of two or more image with parallax information by camera head 2 picked-ups claim figure right, machine 1 is gathered, is stored as calculated, and can on display, show, figure is to after machine software meets many image samplings of three-dimensional imaging parallax requirement and comprehensively waits processing as calculated, by print out equipment 4 outputs, thereby obtain a stereographic map to answer print 5 with stereoscopic parallax information, stereographic map is compound with slit grating or column mirror grating 6 to answer print 5, promptly obtain a stereotome.
As the camera head 2 of image input device can be CCD camera or other camera head, also can be by replacing with computing machine 1 joining image reading apparatus, and scanner can scan one group of figure with stereoscopic parallax information respectively in the computing machine 1 sheet; This set of diagrams can once be taken with many stereo cameras machine sheet, also can equidistantly move a plurality of egative films that repeatedly photograph by one-shot camera, respectively through the common amplification or the photo of enlarging and print and obtaining.
The set of diagrams that constitutes with two pictures is to being example below, and the concrete steps of stereotome method for making involved in the present invention are illustrated.As shown in Figure 1 and Figure 2, two pictures of figure centering can by two camera heads 2 takes simultaneously or by 2 displacements of single camera head once shooting obtain; The about 65mm of the desirable human eye interocular distance of the spacing of two camera heads 2 or the translocation distance of single camera head, the figure of picked-up is received by computing machine 1 converting digital signal to, storage and processing: computing machine 1 is equidistantly cut apart two pictures by the pixel of setting respectively and is in strip Fig. 7, keep single (or two) respectively several numbers then and leave out two (or single) number bar shaped and obtain two strips sampling Fig. 8, again two strip sampling Fig. 8 are merged, to note there be not the direction of parallax during merging, as strict alignment on the vertical direction of photographed, the direction of parallax is being arranged, as centrally aligned on the horizontal direction of photographed, and make the complementary superimposed Fig. 9 of one-tenth of mutual dislocation, with superimposed Fig. 9 by a certain percentage by promptly obtaining stereographic map to answer print 5 after print out equipment 4 printouts; Then figure is carried out compoundly every certain thickness to the interplanar of answer print 5 and grating 6, the parameter of this thickness and grating 6 and the optimum distance of observation stereographic map are relevant, and the transparent material of available different-thickness is controlled as sheet glass 10; Glass 10 is made substrate, and figure is compounded in respectively on two faces of glass 10 answer print 5 and grating 6, promptly obtains a stereotome, notes during composition operation that strip sampling direction and grating fringe orientation are strict parallel.
The control of the value of pixel and superimposed Fig. 9 export ratio will be complementary with employed grating 6 during image sampling, and promptly figure equates with the grating constant of used grating 6 is strict the developed width of each periodic unit in the answer print 5 (comprising from two image strips in two anaglyphs).The grating of existing three-dimensional imaging, its grating constant view sheet size and viewing distance etc. different and different, scope does not wait at 0.1mm to 2mm, as seen 5,6,7,8,9 all be enlarged diagram among the figure, the figure of actual output is much smaller to the grating constant size of answer print 5 strip width and grating 6, and the separation vertical line among the figure does not occur when real image is exported.
