Referring to Fig. 2, the stereo digital camera of a kind of variable twin-lens spacing that the utility model provides includes in the described camera case 1:
Two imageing sensors are connected with two camera lenses respectively, thereby form two cameras by imageing sensor and camera lens, and these two cameras are used for stereo-picture (left eye image and right eye picture) gathered;
Microprocessor is connected with two graphical sensory devices, and described microprocessor is built-in with memory controller and lcd controller, and described microprocessor is used as the control core in the stereo digital camera that the utility model provides;
Constitute double-deck LCD by LCDs and liquid crystal polarization apparatus, be used for the right stereo display of image;

Polarising glass comprises left eyeglass and right eyeglass, and wherein left eyeglass is the vertical polarization sheet, and right eyeglass is the horizontal polarization sheet.
Making and stereo display principle to double-deck LCD describes below.
For the utility model, double-deck LCD is made of a slice liquid crystal polarization apparatus of a slice LCDs and covering on it, and the emergent light of LCDs is a horizontal linear polarization light.The liquid crystal polarization apparatus is that the graphic dot matrix Liquid Crystal Module is peelled off to make by oneself after two polaroids and the backlight and formed, and it is used for the image light that penetrates from LCDs is carried out Polarization Modulation.Be specially: when LCDs showed left eye image, microprocessor was to each pixel of liquid crystal polarization apparatus making alive not, and the liquid crystal polarization apparatus revolves the polarization direction of the linearly polarized light of incident and turn 90 degrees, and becomes orthogonal polarized light; When LCDs show right eye as the time, microprocessor is to each pixel making alive of liquid crystal polarization apparatus, the liquid crystal polarization apparatus can not change the polarization of incident light direction, left eye image and right eye picture penetrate with the timesharing from double-deck LCD of orthogonal two kinds of polarized lights respectively like this, and people's right and left eyes can be observed left eye image and right eye picture respectively by polarising glass.
In the utility model, about the spacing of camera lens, all have vital role and meaning for taking stereoscopic photograph and common photo, be embodied in following several aspect:
One, when changing camera lens spacing baseline, because known-as people's binocular interval be 65 millimeters, its resolving power can reach 1 ' arc angle, binocular stereopsis about 30 meters apart from the time stop when beginning to drop to 230 meters left and right sides, promptly can't distinguish the level apart from object in addition.But, the people bigger to binocular interval, this binocular vision limit point also will correspondingly prolong.
Fig. 3 is for limiting the synoptic diagram of stereoprojection distance, and among Fig. 3, L is a left eye, and R is a right eye, and b is the spacing between two, and the object that d will observe for us, X are the distance of object distance right eye.
When Fig. 3 increases for the spacing when eyes, can make the spacing and the field angle of imaging still can remain unchanged, but need to increase the diagram of projector distance, this principle is called super stereoscopic effect far away when being used for stereographic shooting, and it sees in the requirement at the stereopsis that stretches is extremely useful.
To above-mentioned situation, can be summarized as: when taking stereophotograph as if the stereoscopic camera that equals binocular interval n times with the camera lens spacing, then its stereoeffect is presented as 1/n in size and is presented as 1/n on distance; In other words, if with the camera lens spacing less than the stereoscopic camera of binocular interval (being specially the 1/n that equals binocular interval) take stereotome, when watching with normal binocular interval or stereoscope, the size of its imaging and apart from all being exaggerated 1/n times.Otherwise, if with the camera lens spacing greater than the stereoscopic camera of binocular interval take stereotome, when watching with normal binocular interval or stereoscope, the size and the distance of its imaging all will be dwindled 1/n doubly, need to illustrate, n is greater than zero integer.
Two, hyperstereoscopy.
Hyperstereoscopy can be divided into super near and super far away two types.Among Fig. 4, L is a left eye, R is a right eye, this earlier with (A) of Fig. 4 as object is discussed, promptly the camera lens spacing of used camera is the stereographic map of clapping less than the situation of normal binocular interval, that is to say to surpass closely stereoscopic achievement, when consequently watching with stereoscope, stereoeffect has been subjected to gain, and promptly thing shape is amplified, and aerial perspective is strong.The camera lens spacing is shorter, and gain is bigger, therefore can be used to take the stereotome of miniature toy, insect, clock and watch, Xiao Hua, seedling class or similar object details, can watch the well-bedded stereoscopic picture of imaging and prospect like this.
When adding the macro lens spacing, (c) of the stereotome that stereo digital camera is clapped such as Fig. 4, when watching with normal binocular interval and stereoscope, has super stereoscopic effect far away, make distant objects, particularly be in object outside the binocular stereopsis critical distance, still have suitable front and back level to be seen clearly.This takes extremely useful to being positioned at utmost point landscape, the overlapping chain of mountains at a distance.Therefore, the spacing between the camera lens spacing of baseline-stereoscopic camera or stadimeter, binoculars two object lens is big more, and then its stereoscopic effect is also big more, airborne survey and the photogrammetric usefulness of the earth also all be super stereoscopic photographic equipment far away.
Three, the stereoscopic camera hyperfocal distance determines.
For the stereoscopic camera with variable lens spacing that the utility model provides, its main application is many-sided, both can take tiny nearly thing, also can take outdoor landscape, but is difficult to have concurrently super far away stereoscopic and super closely stereoscopic on same camera.
Usually, when watching a place scenery, do not need all being watched attentively by the object that has entirely to the utmost point far away nearby, only changing by nearby to slightly at a distance view the time, just need be noted some nearly things.With regard to the camera lens of camera, all drop on the object outside the nearer object plane in the focus, that just belongs to hyperfocal requirement.Therefore also can think to have one hyperfocal to normal eyes, to no limit far away, when watching any object, all need not to do apparent material object and watch attentively from this plane.
Preceding 3 meters of eyes are the hyperfocal distances corresponding to eyes, and the binocular integration angle on this distance is 1 °.
For eyes are being looked when seeing stereoscopic photograph, unlikely circle focusing or set and make the eyes anxiety.By twin-lens the nearest face of object in the original stereotome that the stereoscopic camera of spacing claps is arranged, its subtended angle should be too not big, that is to say, shown nearest face should not be shorter than the hyperfocal distance of eyes in stereoscope.
Fig. 5 is for normally looking the synoptic diagram to the effect spacing, in Fig. 5, L is a left eye, and R is a right eye, and b is the spacing between two, B is the spacing between the twin-lens, L ' is left camera lens, and R ' is right camera lens, and A is an object point, D is the vertical range of twin-lens to object point A, and d is the vertical ranges of people's eyes to object point A.
To any specific example. calculating its required camera lens spacing or base length is a simple thing.According to Fig. 5. spacing is that the object point on distance d of the eyes sight that LR looks of b is A.And suppose that it is to be on the hyperfocal distance of eyes.In order to obtain corresponding photographical condition, the spacing of the twin-lens of stereoscopic camera is B, and the latter's subtended angle is identical with subtended angle at A, and supposes and be placed on the nearest face.When the latter was in hyperfocal distance, A was just mirrored in the eyes.
Be not difficult to find out to have the stereoscopic camera of variable lens spacing, its main application is many-sided, both can take tiny nearly thing, also can take outdoor landscape.Weakened the drawback of original stereo digital camera fixed lens spacing to a certain extent.In addition, each camera lens of this camera also can independently use, and can adapt to the needs of taking stereoscopic photograph and common photo.
The stereo digital camera of a kind of variable twin-lens spacing that provides for above-mentioned the utility model, can be by the camera lens of two same sizes, same scenery is taken simultaneously, since two camera lenses of this digital camera can be in sliding tray parallel interlock, thereby change two distances between the camera lens, the needs of can better adaptation taking three-dimensional 3D close shot and three-dimensional 3D distant view, at last, the utility model is handled respectively the image that these two camera lenses obtain by microprocessor, make this a pair of image show by LCDs and liquid crystal polarization apparatus respectively, form double-deck LCD by LCDs and liquid crystal polarization apparatus, this bilayer LCD shows left eye image and the right eye picture of taking the photograph with orthogonal polarized light and the timesharing of horizontal polarization light respectively, the people watches this to having the right and left eyes picture of certain parallax by wearing polarising glass, and then can watch the stereoscopic photograph of oneself taking, experience the stereoscopic visual effect of object.
In sum, compared with prior art, the stereo digital camera of a kind of variable twin-lens spacing that the utility model provides can be adjusted the distance between two camera lenses that it had at any time, satisfies the needs of taking three-dimensional close shot and three-dimensional distant view, stereoeffect is stronger, its main application is many-sided, not only can take tiny nearly thing, also can take outdoor landscape, help strengthening stereo digital camera user's product use experience, be of great practical significance.
The above only is a preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
