Description
Affiliated technical field:
The invention belongs to optics display technique field, the structure that relates to a kind of stereometric camera is formed.
Background technology:
Stereoscopic photograph needs professional equipments such as many lens stereos camera, many lens stereos video camera, because technical difficulty that the flash synchronization particularly of exposing is synchronously realized in multi-lens camera and cost have influenced applying of this class stereoscopic device all than higher.On the other hand, high performance professional film camera, digital slr camera are not particularly also effectively used in personage's stereoscopic photograph in stereoscopic photograph.In order to take stereo-picture with the plane camera, people have been developed two kinds of technology, a kind of be can take about the stereoscopic photograph mirror of two width of cloth images, need to cooperate anaglyph spectacles or stereo viewer to watch stereo-picture; Another kind is use a plurality of cylindrical mirrors or cylindrical lens horizontal, the anaglyph of subject is compressed into perpendicular narrow strip gets off with a shot record then, usually can once take 4 to 5 anaglyphs, be made into the column mirror grating stereo picture by post-production, because horizontal direction is compressed into 1/4～1/5, resolution reduces relatively more seriously.
Summary of the invention:
The objective of the invention is to design a kind of windowing adapter, utilize windowing adapter and photographic apparatus, realize the shooting of stereopsis.
A kind of stereometric camera is made up of photographic apparatus (1) and windowing adapter (2), and by windowing adapter (2), photographic apparatus (1) can be taken the stereo-picture of split screen form, revises with image correction unit for the image deviations that occurs in the photographic process.Windowing adapter (2) is made of dichroic reflector (3) and potential difference catoptron (4), dichroic reflector (3) has the square catoptron of certain difference to be spliced by the polylith reflection angle, potential difference catoptron (4) is one group and equidistantly arranges in the horizontal direction, each reflex block of reflection angle and dichroic reflector (3) is catoptron one to one, and the body that is taken can be recorded on the corresponding blocks of split screen format-pattern after through two secondary reflections.
Photographic apparatus (1) is meant the equipment that comes document image by lens imaging, and typical photographic apparatus comprises film camera, digital camera, video camera, video camera etc., the present invention mainly with digital slr camera as description object.
The effect of windowing adapter (2) is, subject mode with square after a plurality of observation station imagings with horizontal position difference is aligned on the recording medium, and record split screen format-pattern, each observation station is equivalent to the optical center of many lens stereos camera.When the dichroic reflector (3) of windowing adapter (2) was positioned near the focus of photographic apparatus (1) camera lens, the efficiency of light energy utilization was 50～65%, suitably strengthened the distance of dichroic reflector (3) and camera lens, helped to improve the sharpness of image border.Potential difference catoptron (4) can also adopt optics amplifier elements such as cylindrical mirror, spherical mirror to improve coverage.
Dichroic reflector (3) adopts the two-dimensional arrangements of sphere of movements for the elephants shape, and the potential difference catoptron of equidistantly arranging with four levels (4) constitutes windowing adapter (2).Certainly, dichroic reflector (3) can also adopt the two-dimensional arrangements of the capable J row of other I, I 〉=2, and J 〉=2, the potential difference catoptron of equidistantly arranging with I * J piece level (4) constitutes windowing adapter (2).
The deviation that image correction unit utilizes standard picture and correction software to come correction image to occur in shooting process.These deviations mainly come from the geometrical aberration of imaging lens, the reflecting element position deviation of windowing adapter, the optical path difference of each path channels etc.Compare with stereoscopic camera, the combination of imaging lens and windowing adapter is equivalent to a plurality of independently image-generating units of stereoscopic camera, therefore can proofread and correct with patented claim 02104319.1 disclosed method.
The split screen format-pattern is meant two width of cloth disparity maps or several parallax sequence chart is arranged in a width of cloth plane picture in complete image block mode, is kept on the image recording media.The sharpest edges of windowing type stereo technology are, can utilize single image equipment to realize stereoscopic shooting, and are accompanied by the update of vision facilities and are obtaining the upgrading development aspect wide visual angle, the high definition.Split screen mode comprises symmetry split screen and asymmetry split screen.
The feature of symmetry split screen is: parallax sequence image piece big or small identical, divide equally image recording media.Typical split screen mode has four split screens, six split screens, eight split screens, is example with image definition (1024 * 768), can realize that sharpness is 512 * 384 * 4,512 * 256 * 6 stereo display.Obviously, the problem that too high split screen number can bring sharpness to reduce, particularly the one dimension split screen of only realizing on height or direction of width will cause sharpness seriously to descend, thereby not have practical value.
In stereo display, when in a width of cloth anaglyph is at least during a weak point, showing with the desired enough resolution of vision, resolution that can another width of cloth anaglyph of sizable reduction, up to half, and can not cause the decline of sharpness subjective impression, and the decline of depth preception ability.The characteristic of utilizing this asymmetric spatial resolution to require under the constant situation of equipment sharpness, image signal transmission bandwidth, can adopt the asymmetry split screen mode to improve the sharpness of stereo-picture.The feature of asymmetry split screen is: the varying in size of parallax sequence image piece, and the resolution of little image block is not less than half of big image block, and sharpness is as the criterion with the bulk image.Needing to add lens (or post mirror) and catoptron in the part path channels of asymmetry windowing adapter increases image magnification ratio and compensates light path.The emphasis that the asymmetry windowing adapter is not described as the present invention.
Description of drawings:
