Description
Technical field
The invention belongs to the shooting and the imaging new method of three-dimensional film, mainly is a kind of unit polarisation three-dimensional film imaging system and formation method.
Background technology
3 D stereoscopic image is taken and imaging technique is popular in the world at present technology, is used in the production of film and TV field widely.Its captured image has visual impact, and spectators put on the picture energy emersion of watching behind the special glasses or are absorbed in curtain.Along with the 3D motion picture technique is constantly progressive and perfect, the story of a play or opera lengthy motion picture of many complete 3D three-dimensional films that emerged at present.Nowadays, the huge curtain of IMAX film also begins to combine with the 3D three-dimensional film.70 millimeters big screen color solid films have been put on display in build in 1985 in the ripple fair.Nineteen fifty-nine, first two-shipper polarisation three-dimensional film taken by China.
Present 3 D stereoscopic image is a picture of taking down scenery with two camera lenses as human eye from two different directions simultaneously, makes cinefilm; When projection, by two projectors, two groups of films that take with two video cameras are shown synchronously, make this slightly two width of cloth doublings of the image of difference in screen, and at every pre-installed polaroid of projector, its effect is equivalent to the polarizer, the light that penetrates from two projectors is by behind the polaroid, just become polarized light, about the polarization direction of polaroid before two projectors orthogonal, thereby the polarization direction of the two bundle polarized lights that produce is also orthogonal, and this two bundles polarized light projects and reflexes to the spectators place in the screen again, and direction of polarized light does not change, spectators watch with above-mentioned polarising glass, every eyes are only seen corresponding polarized light image, and promptly left eye can only be seen the picture that left machine mirrors, and right eye can only be seen the picture that right machine mirrors, object produces a picture respectively in right and left eyes, these two different slightly pictures are superimposed through remarkable brain, will produce stereo perception, the principle of Here it is three-dimensional film.
The present three-dimensional film mode of watching has (1) light point-score, generally adopts in the cinema.There are many movie theatres all to have the 3D three-dimensional projection Room now, play the film that two video cameras take by two projectors during projection, on screen, will occur two groups of differentiated images synchronously.(2) color separation technology method, this is another kind of 3D stereoscopic imaging technology, also comparative maturity now red indigo plant, red various modes such as green are arranged, but the principle that adopts all is the same.The look point-score can be printed on the image of two different visual angles photographs in the same secondary picture with two kinds of different colors respectively.Video is only just to watch with naked eyes seeing fuzzy ghost image in projection like this, and just can see stereoeffect by the anaglyph spectacleses such as red indigo plant of correspondence, with red blue glasses is example, red eyeglass can only be seen red image down, blue eyeglass can only be seen blue image, two the different images overlapping 3D of presenting stereoeffects in brain that eyes are seen.(3) time-sharing procedure, time-sharing procedure are the application that NVIDIA promotes mainly now, need the cooperation of display and 3D glasses to realize the 3D stereoeffect.The anaglyph spectacles structure that time-sharing procedure adopted is the most complicated, and cost is also the highest certainly.Two eyeglasses all adopt Electronic Control, can carry out the switching of state according to the output situation of display, the printing opacity of eyeglass, light tight switching make human eye can only see corresponding picture (under the light transmission state), and eyes see that different pictures just can reach the effect of three-dimensional imaging.(4) raster pattern, this method can allow the TV programme that receives can three-dimensional, China has now produced the spatical television set of raster pattern, but raster pattern also has shortcoming, be exactly that sharpness and other cubic phase are than difference, only sharpness is high slightly on very large TV, and this also makes the price of cost raise significantly.(5) authentic formula, by unique successful full real three-dimensional television technology in the world today of German Thomas Hou Henglaike invention, original each the standard television equipment compatibility in this stereo TV technique and the whole world, from television production, broadcast system, home television set to the user, all need not to increase any equipment and investment, just when taking three-dimensional program, on video camera, install special device additional and get final product.When spectators watch program, only need put on one pair of special 3D glasses and get final product.Glasses are with low cost, identify through national health department, can not have side effects to eyes.If do not wear glasses with see that common TV is as broad as long, at present such program seldom, this technology is on the verge of being replaced.Shortcoming is that program source is few, and stereoeffect is not very outstanding.(6) observation mirror was exclusively used in the past and saw that the picture that stereoscopic camera claps was right, and picture presents about general.Present this observation mirror also can be seen the left right model three-dimensional film.Can only be at most half size of screen when shortcoming is picture with the aid of pictures or film, advantage be very clear.(7) holographic formula thisly can't be promoted at present.Look it all is three-dimensional in all angles, without anaglyph spectacles.The Soviet Union grinds in the seventies and has tried holographic three-dimensional film, needn't wear glasses when watching, and very big image brilliance scope is arranged.Because the vision accommodation of spectators' eyes and convergence are natures, can not cause overstrain and fatigue, spectators have bigger depth perception than common film, as real-world object as long as rotation head can be seen the change in location as material object.This film is still in the development test stage.
Three-dimensional film adopts curtain previous irradiation shape half-cone lenticulation, limited by the strictness of position, seating area, auditorium, and spectators' head moves the back stereoeffect and can disappear.In the three-dimensional film of watching of wearing glasses, extensively adopting colorized glasses method and polaroid glasses method.The colorized glasses method be about two images taking of two visual angles, with red and blue overlapping printing on the same picture, make a cinefilm respectively.Can use general projection equipment during projection, be that red another sheet is blue glasses but spectators need wear a slice.Make by the eyes of red eyeglass and can only see red image, can only see blue image by the eyes of blue eyeglass.The shortcoming of this method is that spectators' two winks feel uneven, and is tired easily; Advantage is not need to change projection equipment.The three-dimensional film at initial stage is used this method always.Japan built and has put on display the ball curtain black-and-white film that adopts this method in the fair of ripple International Technology in 1985, and effect is better.
The three-dimensional film of polaroid glasses method was paid attention to by various countries since nineteen twenty-two always, and some country combines with wide-field film, clapped into that quality is higher, the color solid film of better effects if.This film is when projection, left and right sides picture can not destroy on the metal curtain of polarization direction with polarization axle 90 ° polarized light projection each other, become overlapping slur, spectators put on 90 ° each other of polarization axles when watching, and with the projection picture the corresponding polaroid glasses of polarized light, can separately obtain stereoeffect to slur.Because making and projection technology is different, the polarisation three-dimensional film has the branch of two-shipper and unit.Unit polarisation three-dimensional film be adopt video camera to clap about three-dimensional even picture, by the special optical device with about solid be coupled to same picture two parts up and down, implementation is arranged above and below, and respectively accounts for two film perforations, is unit anaglyph picture.After projector is joined the polarisation deflecting mirror, just can emit the unit three-dimensional film.The advantage of unit polarisation three-dimensional film is: the cinefilm of saving half; Use a projector projection, save equipment investment; Two pictures can not produce dislocation during projection, guarantee that left and right sides picture is in full accord.Shortcoming is: because the picture area reduces half, Gu the quantity of information luminous flux of picture also reduces.The shortcoming of two-shipper polarisation three-dimensional film is: shooting and projection can't make two machines synchronous fully.
Summary of the invention
The present invention will solve the shortcoming of above-mentioned prior art, and a kind of unit polarisation three-dimensional film imaging system and formation method are provided, and uses unit and light-dividing device to realize the shooting and the broadcast of 3-dimensional image.
