Abstract
The multilens digital stereo camera has structure comprising digital imaging units, image memory, view finder, sync shutter, port power supply, control chip, flash light, etc. The present invention also provides the method of correcting the geometrical aberration of the imaging systems in the stereo camera. The combination of digital stereo camera, the aberration correcting method and digital stereo synthesis technology results in raised stereo picture quality, lowered cost and shortened making period.
Description
The invention belongs to optics display technique field, the structure that relates to a kind of stereoscopic camera is formed.
Along with reaching its maturity of grating stereo imaging technique, the quality of stereoscopic photograph is more and more higher, and cost of manufacture is more and more lower, and stereoscopic photograph begins to be popularized, and many lens stereos camera is the indispensable instrument of non-still life stereoscopic shootings such as personage, animal.Stereoscopic camera in the market is divided into popular and professional, and popular camera mostly is three-lens or four-barrel, takes half range 135 egative films, and professional camera mostly is five to 11 camera lenses, takes 120 egative films.Obtain to have the egative film of parallax by stereoscopic shooting, on three-dimensional enlarger, amplify then, make stereoscopic photograph through processes such as exposure, development, photographic fixing, oven dry, grating are bonding.
Universal day by day along with digital image input-output device, the digital stereo synthetic technology has obtained very great development because of its economic advantage such as convenient.The process of making the digital three-dimensional photo comprises: the photography of (1) digital stereo, (2) software is synthetic, the output of (3) composograph, (4) and the bonding formation stereoscopic photograph of 3 D grating.The present invention mainly separates the problem of still life digital stereo shooting by no means, so-called non-still life is taken, when being meant stereoscopic photographes such as wedding gauze kerchief, art, motion, pet, animal, can not be with single-lens camera follow shot on slide rail, can only be in one line by stereoscopic camera or single-lens camera set, exposure is synchronously taken.Non-still life digital stereo is taken problem and is had only two kinds of solutions at present: one, and adopt stereoscopic camera to take, film scanning is imported computer, obtain several parallax numbers word images, shortcoming is to need to consume sensitive film, film scanning cost height, the cycle is long; Its two, adopt a plurality of digital cameras to take synchronously, then with parallax numbers word image input computer, shortcoming is to require the digital camera volume little, avoids arranging producing excessive parallax, requires design additional shutter synchronization mechanism and image transmitting switch, globality is poor, the cost height.It should be to design a kind of multilens digital stereo camera that non-still life digital stereo is taken the problem best solution.
When taking stereoscopic photograph, no matter be to adopt many lens stereos camera, also be to use a plurality of single-lens cameras (comprising digital camera and traditional film camera), the geometrical aberration between each imaging system is difficult to avoid.Geometrical aberration not only derives from optical lens, the inconsistency of film flatness, each imaging system image distance also can cause the deviation of magnification during exposure, between each parallax egative film (or parallax numbers word image) that shooting obtains except parallax information, also there be a large amount of the interference, increase the sense of feeling dizzy of stereoscopic photograph, reduced image definition and stereoscopic sensation.
The objective of the invention is to design a kind of multilens digital stereo camera, and the geometrical aberration of each image-generating unit of stereoscopic camera is proofreaied and correct.
The structure of stereo digital camera comprises: digital imagery unit (1), video memory (Memory) (2), view finder (3), synchro-shutter (4), port (5), power supply (6), kernel control chip (7) and flashlamp (12).
According to the actual requirements, stereo digital camera can adopt five to 11 identical digital imagery unit (1), and each image-generating unit constitutes by optical lens (8), photoelectric sensor (CCD or CMOS) (9), analog to digital converter (A/D) (10), image processor (DSP) (11).
CCD (Charge Coupled Device), i.e. " charge-coupled image sensor " is a kind of light receiving semiconductor chip, is used to catch figure.When light when camera lens converges to CCD and goes up, photosensitive device induces the electric charge of varying number because of the difference of experiencing light intensity, read circuit by charge transfer circuit, charge information and call over charge information by time clock, be sent to A/D converter, form and the proportional binary number of light intensity the data of the promptly corresponding pixel of this binary number through conversion.CCD charge-coupled device charge stored information, need after ground of synchronizing signal control next bit is implemented to shift, to read, charge information shifts and reads output and need clock control circuit and match with three groups of different power supplys, its circuit is comparatively complicated, because the starting of CCD technology early, technology maturation adopts PN junction or silicon dioxide (SiO2) separation layer noise isolation, the image quality height.Make the stereo digital camera good imaging quality of sensor by CCD, but cost is higher.
CMOS (Complementary Metal Oxide Semiconductor), i.e. " complementary metal oxide semiconductor (CMOS).The image information that the CMOS photoelectric sensor produces after opto-electronic conversion directly produces voltage (or electric current) signal that is directly proportional with light intensity via field effect transistor, is sent to A/D converter and is converted to digital signal, and signal reads very simple.Because CMOS photoelectric sensor integrated level height, distance is very near between each photo electric sensitive element, the circuit, and each other light, electric and magnetic interference are more serious, noise is big, picture quality is relatively poor, and along with the continuous development of cmos circuit noise cancellation technology, the image quality of cmos sensor will further improve.The stereo digital camera image quality of being made sensor by CMOS is poor slightly, but cost is comparatively cheap.
The present invention is reconfiguring based on mature technology mainly, be that structural framing derives from the conventional stereo camera, digital imagery unit, video memory and internal control chip derive from digital camera, therefore the detail of logarithmic code stereoscopic camera such as lens parameters, control circuit, chip etc. are not described in detail, and narrate the bearing calibration of geometrical aberration between the structure of camera and each image-generating unit (1) here emphatically.Only will be clear that camera structure and geometrical aberration bearing calibration,,, also can assemble out stereo digital camera, shoot high-quality digital three-dimensional photo by purchasing suitable parts even be ignorant of the digital camera principle.
Bearing calibration below in conjunction with structure that illustrates stereo digital camera and image-generating unit geometrical aberration.
Fig. 1 is the structural representation of stereo digital camera, comprises digital imagery unit (1), video memory (2), view finder (3), synchro-shutter (4), port (5), power supply (6), control chip (7) and flashlamp (12) etc.
Fig. 2 is the structural representation of digital imagery unit (1), comprises optical lens (8), photoelectric sensor (9), analog to digital converter (10), image processor (11) etc.Light from outside sees through camera lens (8), converges on the photoelectric sensor (9) behind the camera lens; Photoelectric sensor is converted to the analog electrical signal that is directly proportional with light intensity with light signal, is sent to analog to digital converter (10); Analog to digital converter is converted to binary digital signal with analog electrical signal, is sent to image processor (11); Image processor is stored in the storer (2) after data image signal is handled, compressed.Above-mentioned imaging process is to finish under the control of control chip (7).
Fig. 3 is the arrangement position synoptic diagram of seven lens stereo digital camera image-generating units (1) and view finder (3).Image-generating unit (1) one word level equidistantly arranges, view finder (3) be positioned at the intermediate image unit directly over.The optical axis of all image-generating unit camera lenses (8) is parallel to each other and on same surface level, perhaps the optical axis intersection of all image-generating unit camera lenses (8) is in any and on same surface level; View finder can adopt independent optical lens, also can be by additional turning catoptron and the same optical lens of intermediate image units shared, and its structure is identical with 135 slr cameras.
Fig. 4 is standard network point chart board (13), is covered with equidistant site A (14) above, and (x, y), x, y are integer to the position coordinates of known every bit.Here, it not is necessary that each site equidistantly distributes, and chooses so just for convenience of calculation, and the necessary condition of network point distribution is that every coordinate is known, and can be corresponding one by one with the point on the distorted image (15).Carry out when correcting captured, simpler method is a distance, dead ahead that on-gauge plate (13) is just being placed stereoscopic camera intermediate image unit, make and have a few on the on-gauge plate (13) all and can on the distorted image (15) of whole image-generating units (1), manifest, and the site of distorted image (15) distribution all over the screen as far as possible, press the shutter shooting and can write down several distorted images, calibrated processing (the treatment for correcting method will describe in detail at the paragraph of back) obtains going back original image.Utilize a plurality of image-generating units that the on-gauge plate of same position is taken the correction data that obtains, when solid space shooting figure is carried out treatment for correcting, in fact also introduced additional parallax in the original image, but this additional parallax has positive effect at every width of cloth.More accurate method is the same distance place, dead ahead that on-gauge plate (13) is just being placed each image-generating unit respectively, takes the distorted image of all image-generating units of record several times.
Fig. 5 is distortion halftone dot image (15), through the digital picture pre-service, each stain on the image is refined into a pixel A ' (16).(x y), is imaged as A ' (x ', y ') through image-generating unit (1) to site A on the on-gauge plate.
Following paragraph mainly illustrates the functional structure of correction principle, method and the correction software of distorted image.
Geometric distortion all is by conventional coordinates (x arbitrarily, y) to distorted coordinates system (x ', y ') conversion, this explanation should appear at the picture position (x, pixel value t y) (x, y), after the image-generating unit imaging, appear at distorted image (x ', y ') locate, the pixel value of establishing this point is f (x ', y ').The correction of this distorted image is actually mapping transformation, promptly t (x, y)=f (x ', y ').We only need according to site coordinate known on the on-gauge plate (x, y) with the corresponding relation of distorted image site coordinate (x ', y '), by interpolation method find out coordinate system (x, y) in institute a B (x is arranged
0, y
0) (correction of whole distorted image just can be finished, i.e. t (x in α, β) (18) to (17) position B ' in distorted coordinates system (x ', y ')

0)=f (α, β), wherein, x
0=0,1,2 ..., w-1; y
0=0,1,2 ..., h-1; W, h are respectively the number of proofreading and correct back image horizontal stroke, vertical pixel.
The bearing calibration of distorted image can follow these steps to carry out:
At first, set two two-dimensional array C and D, be used for the storage standards coordinate system (x, y) with distorted coordinates system (x ', y ') between mapping relations.If (x, y) for on-gauge plate (13) n are listed as the coordinate of the capable site of m, x=n*p then, y=m*p, wherein p is an integer, represents the spacing between the site, and the value of p is more little, and the geometrical aberration correction accuracy is high more, 0≤x≤w-1,0≤y≤h-1.(x ', y ') be the coordinate that distorted image (15) is gone up corresponding point, the value of x ', y ' is read by software, is stored in then in the array, i.e. C[x] and [y]=x ', D[x] [y]=y '.
Obviously, most of elements of array C and D are by assignment, below we calculate α and β, with element assignment all in the array.

Here α and β differ and are decided to be integer, so can not overlap with any point in the coordinate system (x ', y ') usually, promptly can not find corresponding pixel points in distorted image, can take two kinds of methods to handle:
First method is simpler, and promptly the pixel value with neighbor point replaces.Find with (α, β) hithermost point records its coordinate figure among array C, the D C[x
0] [y
0]=MOD (α+0.5), D[x
0] [y
0]=MOD (β+0.5), all array elements all have been endowed coordinate figure.Two-dimensional array C, D are exactly the table of corrections of image-generating unit (1), as long as table of corrections has been arranged, the correction of distorted image is very simple:
T (x
0, y
0)=f (C[x
0] [y
0], D[x
0] [y
0]) that is to say that read coordinate figure in order from table of corrections, according to coordinate figure read pixel value in distorted image, forming new image is correcting image.
Second kind of disposal route is complicated, and (α, the pixel value of four neighbor points β) determine that by certain interpolation method (α, (α β), revests correcting image t (x to pixel value f β) then need to read encirclement in distorted image
0, y
0)=f (α, β).
The calibration software module of distorted image should comprise following function:
1, the distorted image pre-service.Distorted image to on-gauge plate is taken through pre-service such as binaryzation, contractions, is refined into a pixel with each site, and pixel coordinate is recorded in the array, sets up the site mapping relations between standard drawing and the distorted image.
2, the coordinate interpolation.Coordinate points between the segmentation site is set up the pixel mapping relations between standard drawing and the distorted image.
3, set up table of corrections.According to the pixel mapping relations between standard drawing and the distorted image, set up the mapping table of each image-generating unit from the distorted image to the correcting image.
4, the correcting distortion image.Utilize the mapping table of each image-generating unit, proofread and correct any distortion anaglyph of taking from solid space.
