Abstract
The utility model relates to a digit polarization space division image device, by constituteing in projector (1), polaroid combination (2), polarising glass (3), curtain (4) and computer (5), polaroid combination (2) sets up in projector (1) front side, the perpendicular setting of light of curtain (4) and projector (1), curtain (4) amount to captions cloth, computer (5) are connected with projector (1) and curtain (4) respectively. Projector (1) is DLP projector, including two projecting apparatuss. Polaroid combination (2) includes the analyser lens of two mutually orthogonals including the polarizer of two mutually orthogonals, polarising glass (3). The utility model provides a two effects that two projected image were watched respectively to eyes about digit polarization space division image device has realized. The refresh rate of projector requires than lower. Spectator only need wear the lighter polarising glass of weight and just can realize watching, and the price of glasses is also cheap relatively. Image separation degree is high, and viewing effect is good.
Description
Technical field
The utility model relates to a kind of digit Polarization compartition imaging device of compartition mode 3-D display, belongs to 3-D display field.
Background technology
There is spacing (average interpupillary distance value is 60mm) in the horizontal direction in two eyes due to people, therefore for same scenery, on the retina of right and left eyes, imaging relative position is variant, this species diversity just can form three-dimensional perception by cerebral neural process, binocular parallax principle that Here it is.Parallax display is exactly based on binocular parallax principle, to be synthesized by computing machine or multiple-camera shooting has two width images of parallax, also referred to as " stereoscopic to ", by some beam splitters, make observer's right and left eyes see the two dimensional image of corresponding different visual angles respectively, merged by brain and form 3-D view.Different according to the stereoscopic right mode of separation, binocular parallax display can be divided into utility appliance display, integration imaging display and Auto-stereo display two class.Beholder needs to wear the glasses of specifying or the helmet just can see stereo-picture.Existing spectacle comprises frequency division, time division according to dividing as the unusual of principle.
Frequency division mode easily realizes, cost is low, but there is the problems such as color is dimer, height loss serious, crosstalk, and comfort is very poor.Time division mode requires that the frame frequency of display is the twice of regular display, generally needs to reach 120hz, so just there will not be flicker problem.And liquid crystal shutter glasses is expensive, many people watch can increase cost.
Utility model content
In order to overcome the deficiencies in the prior art, resolving the problem of prior art, making up the deficiency of existing existing product in the market.
The utility model provides a kind of digit Polarization compartition imaging device, be made up of projector, polaroid combination, polarising glass, curtain and computing machine, described polaroid combination is arranged on front side of projector, described curtain is vertical with the light of projector to be arranged, described curtain is digital curtain, and described computing machine is connected with projector and curtain respectively.
Preferably, above-mentioned projector is DLP projector, comprises two projector.
Preferably, above-mentioned polaroid combination comprises two mutually orthogonal polarizers, and polarising glass comprises two mutually orthogonal analyzer eyeglasses.
Preferably, AD converter is provided with between above computer and projector.
Preferably, two projector of above-mentioned projector respectively corresponding polaroid combine two different polarizers.
The digit Polarization compartition imaging device that the utility model provides achieves the effect that two, left and right eyes watch two projected images respectively.The refresh rate of projector requires lower.Spectators only need the polarising glass wearing lighter in weight just can realize viewing, and the price of glasses is also relatively cheap.Separation of images degree is high, and viewing effect is good.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Reference numeral: 1-projector; 2-polaroid combines; 3-polarising glass; 4-curtain; 5-computing machine.
Embodiment
Understand for the ease of those of ordinary skill in the art and implement the utility model, below in conjunction with the drawings and the specific embodiments, the utility model being described in further detail.
The digit Polarization compartition imaging device that the utility model provides, be made up of projector 1, polaroid combination 2, polarising glass 3, curtain 4 and computing machine 5, polaroid combination 2 is arranged on front side of projector 1, curtain 4 is vertical with the light of projector 1 to be arranged, curtain 4 is digital curtain, and computing machine 5 is connected with projector 1 and curtain 4 respectively.Projector 1 is DLP projector, comprises two projector.Polaroid combination 2 comprises two mutually orthogonal polarizers, and polarising glass 3 comprises two mutually orthogonal analyzer eyeglasses.
AD converter is provided with between computing machine 5 and projector 1.Two projector of projector 1 respectively corresponding polaroid combine 2 two different polarizers.
The digit Polarization compartition imaging device that the utility model provides, stereoscopic the projector 1 that image consists of two projector to be projected, projection ray is respectively by mutually orthogonal two polarizers in polarization direction, and two bundle polarized lights of generation are projected on same screen 4.Beholder wears the polarising glass 3 that the polaroid corresponding with the polarizer is made, and utilizes the polarization characteristic of polarized light to realize the separation of horizontal parallax image.The 3-D display of which needs two identical projectors 1 of parameter, for DLP projector.The light projected is the natural light not fixing polarization direction.After analyzer, luminous energy at least loses half, becomes linearly polarized light.Linearly polarized light is projected on special curtain 4, and this curtain 4 will ensure that the polarization state of polarized light does not change, and last polarized light enters human eye through analyzer again.Finally achieve the effect that two, left and right eyes watch two projected images respectively.The refresh rate of projector requires lower.Spectators only need the polarising glass wearing lighter in weight just can realize viewing, and the price of glasses is also relatively cheap.Separation of images degree is high, and viewing effect is good.
The embodiment of the above is better embodiment of the present utility model; not limit concrete practical range of the present utility model with this; scope of the present utility model comprises and is not limited to this embodiment, and the equivalence change that all shapes according to the utility model, structure are done is all in protection domain of the present utility model.
