Abstract
The present invention discloses a real-time synthesized stereoscopic and cartoon photographic method and a device thereof. A camera of the present invention comprises a telescopic camera body, a camera lens seat and a film jacket holder which carries a lenticular screen and an image recording material. In a shooting process, the camera moves along a suite of linear sliding track to a predetermined distance and simultaneously deflects around an object to be shot. Under the combined action of two movements, the camera scans the object to be shot from every side and focuses rays on the lenticular screen which secondarily focuses the rays which are imaged on an image recording material. In a scanning process, the camera lens seat and the film jacket holder deflect at respectively predetermined angles and in respectively predetermined directions so that images at different scanning angles can be imaged in different positions of the image recording material and be synthesized stereoscopically in real time. Due to large shooting angles and large scanning angles, the present invention is capable of shooting uncountable continuous multi-azimuth pictures of sceneries and has the advantages of strong stereo perception and little image jittering and flicker.
Description
The present invention relates to the method and apparatus of a kind of solid and cartoon photographic, especially a kind of can multi-faceted continuous shooting, synthetic in real time stereoscopic photograph method and device.
We live in the three-dimensional world, and all existing height and width of any object wherein have the degree of depth again., traditional photography can only be taken 2-dimentional photo, promptly can only reflect the photo of the height and width of subject.Therefore, since the nearly century, many inventors are attempting inventing the camera that can take stereoscopic photograph.This photo can also reflect its degree of depth in the height and width of reflection subject.
People's vision system obtains three-dimensional consciousness by many visual cues, and parallax is the wherein the most effective clue.When the people watched an object attentively, two eyes were pass by from a different perspective, thereby formed two slightly different images.Right eye is more seen the right of this object, and left eye is more seen the left side of this object.People's vision system can extract depth information from the parallax of two video corresponding point.Produce stereoscopic perception in order to use principle of parallax, camera must produce the image that at least two width of cloth have binocular parallax, and this two width of cloth image can receive respectively for two institutes.
Now existing a lot of methods can produce stereoscopic photograph.A kind of method of using the earliest is the binocular stereoscopic imaging method, and this method uses two cameras or a camera at two different locus photographs two width of cloth images.When watching, by means of certain special equipment, people's right eye is only seen the image of clapping from the right side, and left eye is only seen the image of clapping from the left side.This two width of cloth image is synthetic automatically in human brain, forms a width of cloth stereo-picture.Because such image is only synthetic by two width of cloth two dimensional images, can only see the static stereo-picture in an orientation of scenery when watching as stereoscope by device.The three dimensions imaging technique is called again from the three-dimensional imaging technology, is the significant improvement to stereoscopic imaging technology.In the three-dimensional imaging technology, the camera multiple photos, then these several photos synthesize a width of cloth stereoscopic photograph through aftertreatment.The quantity of information (quantity that depends on the 2-dimentional photo that is used for the compound stereoscopic photo) that such width of cloth stereoscopic photograph is contained is much larger than the quantity of information of the photo that uses binocular stereoscopic imaging method gained.If the observer is being shielded moving-head when watching photo by certain device as column mirror screen or slit, he can feel watching same object from different directions, watches object very similar in this real world of feeling to coexist.
When a kind of implementation of three-dimensional imaging technology is shooting, use a multiple lens camera, perhaps use an one-shot camera, but this camera can move to different locus.Each of subject not ipsilateral clapped by camera, and then these photos (are used optical devices or computing machine) in some way and synthesize stereoscopic photograph.China Patent No. is 93203576.0 " small-sized four-barrel stereocamera ", and U.S. Patent number is that 5337096 and 4800407 patent promptly is this kind design.A major defect of these class methods is that image has the sense of jump when watching: when observer's moving-head, he can see that image becomes another width of cloth from a width of cloth hop jump, and hop jump becomes an other width of cloth again.This jump is because it is discrete being used for the two dimensional image of synthetic stereo image, and is discontinuous.Another shortcoming of this method is three-dimensional synthetic can not the acquisition in real time.Must be through one post processor, time-consuming, may be directed at error again.In addition, the general number of shots of multi-lens camera is few, and the camera lens spacing is little, thereby synthetic photo observation visual angle is little, and stereoscopic sensation is not strong.
Realization is that the anthropomorphic dummy observes the process of seeing from a kind of preferred mode of three-dimensional imaging technology, uses an one-shot camera scanning subject.This camera must possess certain mobile means, so that from the angle continuous sweep subject of conversion.This continuous sweep method is compared with discrete image pickup method, and the photographic intelligence amount increases greatly, thereby observed bearing is wide, and it is few to beat, and stereoscopic sensation is strong.This kind smear camera combines with column mirror screen or slit screen usually, and the latter is positioned near the camera focal plane, and is positioned at before the sensitive film that is used for document image.Removable camera and column mirror screen or slit screen combine the real-time acquisition that causes stereoscopic photograph, thereby avoided the post processor of the necessary complexity of many lens shootings.
What United States Patent (USP) 2508587 was proposed promptly is a kind of like this method.In this design, camera moves along an arc track, and the center of this arc track is the place of subject.In scanning process, camera lens is always facing to subject.Another together motion be column mirror screen and be close to thereafter sensitive film in the camera movement process around a Z-axis with respect to camera lens deflection.The application of this camera is restricted, because subject is pre-determined to the distance of the camera radius by arc track, can't change.
United States Patent (USP) 4107712 has proposed the another kind of camera designs of application scanning method.In this design, the body of camera is fixed in whole scanning process.The little diaphragm of camera lens back scans the incident ray by camera lens in the horizontal direction when shutter opening.Be positioned near the column mirror screen in camera lens focal plane and move a predefined distance with the moving direction straight line identical with little diaphragm, sensitive film is then the same with the camera body to be maintained static.The weak point of this design is: 1, it needs a heavy caliber, and high-quality camera lens, this camera lens are difficult to make; 2, the diaphragm scanning distance is less, thereby the photo viewing angle of taking the photograph is little, and stereoscopic sensation is not strong; 3, the about pitch of the small movements of column mirror screen needs high-quality control system, and any error of this system all can cause the quality of gained stereoscopic photograph to descend.
China Patent No. is that " Stereophotography apparatus with single objective lens multi-slit scanner " described camera designs of 94237196.8 comprises two set of shots: one group is common lens, and another group is the macroshot camera lens.This design has replaced column mirror screen with the slit screen.The assembly that does relative motion in exposure process has the camera body, macroshot camera lens, and slit screen.The camera body moves along rectilinear orbit, and meanwhile macroshot camera lens and crack screen is done rectilinear motion in the opposite direction.A real-time compound stereoscopic photo produces therefrom.The motion that this designing institute relates to is more more complicated than above-mentioned United States Patent (USP) 4107712, and the quality of final photomontage will be subjected to the restriction of each kinematic accuracy.And this design only is used for 120 little pictures, if amplify, has complicated aftertreatment work, has lost synthetic in real time meaning.
As mentioned above, oneself has many ready-made designs aspect stereoscopic imaging technology, but also has various problems, and it is high-quality to make that these designs can't produce, the stereoscopic photograph of sensation nature.
Fundamental purpose of the present invention is exactly method and the device that a kind of real-time compound stereoscopic and cartoon photographic are provided at the deficiency of prior art, it does not need can produce the method and apparatus of synthetic in real time stereo-picture through any complicated post processor (except film rinsing and the attaching column mirror screen).

Referring to Fig. 1-5, describe image-forming principle of the present invention and method in detail.
In order to obtain the continuous image stronger with stereoscopic sensation, camera must be done continuous sweep to subject in a big scope, thus the shot object multi-aspect information.When this kind continuous sweep method guarantees observer's moving-head, can in a big way, see the not ipsilateral of subject continuously, rather than see that a picture saltus step becomes another picture.Big scan angle is another key element that makes stereo perception outstanding.The scan angle of camera is defined as line and the formed angle of line from the camera sweep stopping point to subject from the camera sweep starting point to subject.This angle increases with the increase of the straight line displacement of camera, accompanys or follow camera and reduces to the increase of the distance of subject.The present invention uses big camera straight line displacement, thereby has obtained big relatively scan angle.
Should form stereoscopic photograph in real time with correct depth information.If do not do any adjustment after column mirror screen put into camera, each post mirror unit on the column mirror screen is to incident ray imaging again, can cause image to produce opposite depth perception, promptly object is being seen to resemble and is being ensconced the back in fact the preceding, and in fact after object seeing and resembling in front.The present invention has adopted the compensating motion of column mirror screen with respect to the deflection of camera lens, can synthesize the image with correct depth relation in real time.Its synthetic in real time characteristics make this method faster and more accurate than the method for all use post processors.
And existing flickering refers to brightness irregularities on the stereoscopic picture plane in the prior art, and it is that exposure area deficiency or repeated exposure by each post mirror unit imaging of column mirror screen causes.Here relate to two angles, one is the scan angle of column mirror screen upper prop mirror unit, is defined as the angle of two limit incident raies about the post mirror unit; Another is the image angle of post mirror unit, and it is a technical indicator of column mirror screen, by the cylinder radius of post mirror unit, and thickness, and pitch determines.The reason of exposure area deficiency is the image angle of the scan angle of post mirror unit less than the post mirror unit, and repeated exposure then results from the scan angle of post mirror unit greater than the image angle of post mirror unit.Therefore, only when these two angles equate, could eliminate flickering, obtain the even brightness stereoscopic picture plane.
For reaching this, at camera lens, between subject, column mirror screen and the image recording material relative motion to be arranged in the scanning process from three-dimensional photography.Any error in these Relative motion control all can cause image quality decrease.For example, not precisely controlled as the relative motion of camera lens and column mirror screen, can present vertical dark fringe or bright fringes on the stereoscopic photograph, and phenomenons such as degree of depth compression or expansion.Therefore, before scanning, adjust the amplitude of relative motion easyly, in scanning process, strictly control relative motion, become key then from the success of three-dimensional imaging technology.
Referring to Fig. 1,, scan subject 10 when camera 12 moves along line slide rail ABC.Camera lens seat 30 makes camera lens optical axis aim at subject 10 in whole scanning process around pivot point 24a deflection.L and r represent the left side and the right side in subject space.Light r, m and 1 represent respectively at two extreme position A and C, and centre position B is incident to the chief ray of camera from subject 10.2 β are angles of light r and l, and it has represented the scope of camera 12 in object space scanning.Camera sheet holder 14 is positioned at the rear portion of camera 12, and it is loaded with column mirror screen and image recording material.Because the camera lens of camera 12 all points to subject 10 in whole scanning process, this method has guaranteed to utilize to greatest extent the aperture of camera lens when producing stereoscopic photograph.
Referring to Fig. 1, camera sheet holder 14 also is the motion of column mirror screen 28 as can be known.If camera sheet holder 14 remains unchanged with the relativeness of lens mount 30 in whole scanning process, the image of Pai Sheing can drop on the same position of image recording material 26 from different perspectives, has no idea to separate, thereby can't obtain stereoscopic sensation.In order to separate different images, camera sheet holder 14 must be with respect to lens mount 30 motions in scanning process.In the present invention, camera sheet holder 14 is on pivot point 24b, and is axle with the perpendicular bisector.In the A position, camera sheet holder 14 becomes counterclockwise angle with baseline BL dotted line.In the B position, camera sheet holder 14 is parallel with baseline BL.In the C position, camera sheet holder 14 becomes clockwise angle with baseline BL.And the optical axis of camera lens is always perpendicular to baseline BL, and intersects with sheet holder perpendicular bisector.
Fig. 2 a to 2c has described at three scanning position A, B, C, the imaging procedures of the part post mirror unit of column mirror screen 28 central authorities.The post mirror unit in bosom and its two next-door neighbours have only drawn among the figure.The meaning of L and R is similar with the front, promptly points out the corresponding imaging of object space left and right directions.Because an imaging of camera lens resembles for counter, L on the face of resembling, the direction of R is just in time opposite with object space.Pr, Pm, P1 become image point with 1 for three chief ray r, m marking among Fig. 1 on sensitive film.All light is the photocentre 0 by the post mirror unit all, so its direction is not changed by the refraction on post mirror unit surface.To point out a bit that also promptly every bit is that the light with certain clear aperature by the center is formed with the chief ray by a branch of on the post mirror unit focal plane, and its chief ray that only drawn in the drawings.Can derive from the principle of plane geometry, chief ray r, m and 1 and the angle of column mirror screen 28 normal n equal the angle of camera sheet holder 14 and baseline BL.Therefore, this angle equals α in A position and C position, and equals 0 in the B position.Release thus, the scan angle of column mirror screen 28 is 2 α.
Fig. 3 has described the geometrical construction of a certain post mirror unit on the column mirror screen 28.This post mirror unit has an optical centre 0, cylinder radius r L, pitch P, thickness t.The image angle of post mirror unit is 2 φ, and it is drawn by following formula:
2 φ=2arctan{P/ (2t-2rL) } in order to take high-quality stereo-picture, the column mirror screen thickness t should equal the focal distance f of post mirror unit, and scan angle 2 α of column mirror screen 28 should equal image angle 2 φ of post mirror unit.
Fig. 4 is the situation when watching the stereo-picture of being taken by camera 12.Owing to Fig. 2 is the Polaroid reverted image that is, will overturn when watching is erect image, and its left and right orientation is opposite with Fig. 2.When the observer watched image with bore hole, right eye Er received the light from picture point Pr, and left eye E1 receives the light from picture point P1.Return Fig. 2 now.Picture point Pr and P1 are formed r and 1 by chief ray, right side imaging of the same area and left side imaging in their representative spaces.Therefore, what observer's right eye was seen is resembling of the right side, is resembling of the left side and left eye is seen, thereby the correct depth that has guaranteed this stereo-picture shows.
