The utility model passes through technique scheme, the beholder watches the 3D anaglyph of left and right sides form, just can in brain, form the 3D stereo-picture, can keep existing left and right sides form 3D and help the high advantage of view apparatus color fidelity, can keep angular magnification again in the vertical direction is 1, and angular magnification reaches about 2 in the horizontal direction, thereby allows the eurythmy of the 3D rendering that the beholder sees; In addition, left cylindrical lens and right cylindrical lens adopt the cylinder Fresnel lens, have both reduced cost, have improved image quality again.
[description of drawings]
Fig. 1 is the structural representation of a kind of stereopsis playback system embodiment described in the utility model.
[embodiment]
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
As shown in fig. 1:
The described a kind of stereopsis playback system of the utility model embodiment includes cylindrical mirror stereopsis sight screen 1 and display screen 2, and described cylindrical mirror stereopsis sight screen 1 is located at the centre position between display screen 2 and the beholder's eyes 3; Wherein, described cylindrical mirror stereopsis sight screen 1 mainly is made up of left cylindrical lens 11 and right cylindrical lens 12, described left cylindrical lens 11 and right cylindrical lens 12 design side by side and are adjacent to mutually and connect, and all can be the cylinder Fresnel lens, its focal length is all smaller or equal to 50cm, and the distance between described cylindrical mirror stereopsis sight screen 1 and the display screen 2 is smaller or equal to the focal length of left cylindrical lens 11 and right cylindrical lens 12; 3D rendering is presented on the described display screen 2 with left and right sides form, form side by side left eye image district 21 and right eye picture district 22, the photocentre of described left cylindrical lens 11 and right cylindrical lens 12 faces the axis in left eye image district 21 and right eye picture district 22 respectively, perhaps outside the axis facing to left eye image district 21 and right eye picture district 22, be the photocentre of left cylindrical lens 11 side of taking back over against the center in left eye image district 21 or in the axis in left eye image district 21, the photocentre of right cylindrical lens 12 side that takes over over against the center in right eye picture district 22 or in the axis in right eye picture district.
In addition, between the photocentre of described left cylindrical lens 11 and right cylindrical lens 12 apart from d=cf/u, wherein c is the distance between the axis in left eye image district 21 and right eye picture district 22, f is the focal length of left cylindrical lens 11 and right cylindrical lens 12, and u is the distance between left cylindrical lens 11 and right cylindrical lens 12 and the display screen 2.
Height l 〉=the hu/D+4mm of described left cylindrical lens 11 and right cylindrical lens 12, wherein h is the height of left viewing area 21 and right viewing area 22, u is the distance between left cylindrical lens 11 and right cylindrical lens 12 and the display screen 2, D is the distance between beholder's eyes 3 and the display screen 2, and 4mm is the diameter of beholder's eye pupil.
The mm of the width b of described left cylindrical lens 11 and right cylindrical lens 12 〉=(c+65)/2, wherein c is left eye image 21 and right eye as the centre distance between 22,65 unit is mm, the average interpupillary distance of expression human eye.
The principle of work of stereopsis playback system described in the utility model is: the image angular magnification Г in the horizontal direction on the display screen 2 that the beholder sees by cylindrical mirror stereopsis sight screen 1 is:
Wherein, D is the distance between beholder's eyes 3 and the display screen 2, and u is the distance between left cylindrical lens 11 and right cylindrical lens 12 and the display screen 2, and f is the focal length of left cylindrical lens 11 and right cylindrical lens 12; Work as D=2u, and during u ≈ f, angular magnification Г ≈ 2, then the left eye image district 21 on the display screen 2 and right eye picture district 22 are under the situation of demonstration all over the screen, In the view of the beholder, the width (horizontal direction) in left eye image district 21 and right eye picture district 22 has been exaggerated nearly one times, and the size of height (vertical direction) is not amplified, and the 3D figure that finally forms in human brain has just recovered normal ratio.
For example: display screen 2 is the display screen of ipad, its width is 200mm, highly be 140mm, the viewing distance (being the distance B between eyes 3 and the display screen 2) of people's custom is about 530mm, accordingly, the focal distance f of left side cylindrical lens 11 and right cylindrical lens 12 is 280mm, between left side cylindrical lens 11 and right cylindrical lens 12 and the display screen 2 is 270cm apart from u, be 104mm apart from d between the photocentre of left cylindrical lens 11 and right cylindrical lens 12 then, the height l of left side cylindrical lens 11 and right cylindrical lens 12 is 75.3 mm, and width b is 82.5 mm.The horizontal direction magnification is 1.9.
Like this, the 3D anaglyph of watching left and right sides form by cylindrical mirror stereopsis sight screen described in the utility model and stereopsis playback system, the beholder just can form the 3D stereo-picture in brain, can keep existing left and right sides form 3D and help the high advantage of view apparatus color fidelity, can keep angular magnification again in the vertical direction is 1, and angular magnification reaches 1.9 in the horizontal direction, thereby realizes the eurythmy of the 3D rendering of reproduction; In addition, left cylindrical lens 11 and right cylindrical lens 12 adopt the cylinder Fresnel lens, have both reduced cost, have improved image quality again.
Above content be in conjunction with concrete optimal technical scheme to further describing that the utility model is done, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the professional and technical personnel of technical field under the utility model, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be considered as belonging to protection domain of the present utility model.
