Abstract
The utility model relates to a suspension stereoscopic display system, including a plurality of projectors (1), a plurality of rotatory diaphragm (2) and screen group (3), screen group (3) comprise a plurality of rotating screen, and projector (1) corresponds diaphragm (2) and sets up, and rotating screen corresponds rotatory diaphragm (2) and sets up, is provided with protection glass (4) in screen group's (3) top. A week, projector's syncline top slope are arranged by a plurality of projectors on the horizontal plane. Rotating screen and rotatory diaphragm (2) equal perpendicular to projector (1) optical axis direction are placed. The play pupil of projector (1) is constituteed the strip through the screen with protection glass (4) again and is gone out the pupil through rotatory diaphragm (2). The utility model provides a suspension stereoscopic display system can satisfy 360 panoramas to be watched, and protection glass has increased the security guarantee, has also realized the reference of hoverheight, is more comprehensive, effective, safe stereoscopic display equipment.
Description
Technical field
The utility model relates to a kind of novel panorama, suspends, and tangibly three-dimensional display system, particularly relate to a kind of suspension three-dimensional display system, belong to Volumetric display technical field.
Background technology
Three-dimensional stereo display technique gives observer with impression on the spot in person to a certain extent, the scene of objective world can be reappeared truly, the depth perception of displaying chart picture, stereovision and authenticity, its application widely, as medical science, building, visualization in scientific computing, video display amusement, military training, video communication etc.The anaglyph spectacles used when watching three-dimensional film now, technology is comparative maturity, but it only has two width disparity maps, and the disparity map of auto-stereoscopic display also only has 9 width, only can form eight anaglyphs pair, and range of observation is by considerable restraint.But people are no longer satisfied with less range of observation, and have the view mode of distance perspective and estrangement sense, wish that obtaining one can panorama watch, stereopsis suspends, and tangibly three-dimensional display system.The 3D stereo display technique overwhelming majority is now not very touch-type, and namely observer and stereopsis are in a distance, there is estrangement sense, can not realize man-machine interaction.
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 suspension three-dimensional display system; comprise multiple projector, multiple rotary diaphragm and group of screens, described group of screens is made up of multiple Rotation screen, and the corresponding diaphragm of projector is arranged; Rotation screen corresponding rotation diaphragm is arranged, above group of screens, be provided with cover glass.
Preferably, above-mentioned multiple projector arranges one week in the horizontal plane, and projector tilts obliquely upward.
Preferably, above-mentioned Rotation screen and rotary diaphragm are all placed perpendicular to projector light direction of principal axis.
Preferably, the emergent pupil of above-mentioned projector through rotary diaphragm, then forms strip emergent pupil through screen and cover glass.
Preferably, above-mentioned Rotation screen comprises multiple Fresnel Lenses.
The suspension three-dimensional display system that the utility model provides can meet 360 ° of panorama viewings, and cover glass adds security guarantee, also achieves the reference of hoverheight, is that one is more comprehensive, effective, safe stereoscopic display device.

Reference numeral: 1-projector; 2-rotary diaphragm; 3-group of screens; 4-cover glass; 5-bar shaped emergent pupil; 6-human eye.
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 suspension three-dimensional display system that the utility model provides, the directional screen group 3 that the projection unit be made up of some minitype projection machines 1, four groups rotates, and four groups of rotary diaphragms 2 form.Minitype projection machine arranges one week in the horizontal plane, and projector tilts obliquely upward, and four groups of screens rotated and four groups of rotary diaphragms are all placed perpendicular to projector light direction of principal axis.The emergent pupil of projector through rotary diaphragm, then forms strip emergent pupil through directional screen.Projector's horizontal rotary puts one week, directed screen and rotary diaphragm carry out synchronous rotary, the observation domain of system is the seamless spliced cone space of a series of bar shaped emergent pupil, when eyes are positioned at two different emergent pupil places of cone space, according to binocular parallax principle, right and left eyes can see two width disparity maps respectively, after brain merges, produce stereopsis, can feel that stereopsis is just suspended on directed screen, obtain close to real stereoscopic sensation.
As shown in Figure 1, realize suspension effect needs consideration three aspects to the principle of work of the suspension three-dimensional display system that the utility model provides: (1), by the parallax of change two disparity maps, makes stereopsis emersion screen; (2) working method that projector 1 projects obliquely is taked.This working method not only ensure that the stereopsis of synthesis can emersion group of screens 3, be positioned at the top of spin orientation group of screens 3, and direction of observation is pleasant, can arranges some projectors more; (3) cover glass 4 is installed in directed screen top, and cover glass 4 both can have safeguard protection effect to beholder, also can as the basis of reference of stereopsis hoverheight.
In order to realize the imaging of system, need a condition: the emergent pupil of projector 1 projection objective and the entrance pupil of system below will overlap and dock, and aperture diaphragm also must be positioned at this joint.But because the emergent pupil of existing most of projection lens is all inside projector, in this case, if rotary diaphragm directly switches image, the cutting of visual field will be caused, so special projector must be selected in this three-dimensional display, this projector requires that the emergent pupil of its projection objective is positioned at outside, is namely positioned at the rotary diaphragm place of system, as shown in Figure 2.
The suspension three-dimensional display system that the utility model provides can meet 360 ° of panorama viewings, and cover glass adds security guarantee, also achieves the reference of hoverheight, is that one is more comprehensive, effective, safe stereoscopic display device.
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.
