The utility model provides an intelligence suspension bore hole stereoscopic display equipment 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

Intelligence suspension bore hole stereoscopic display device

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 intelligent suspension bore hole stereoscopic display device, 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.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 intelligent suspension bore hole stereoscopic display device; comprise multiple projector, multiple rotary diaphragm, Fresnel Lenses group and computing machine; described Fresnel Lenses group is made up of multiple Fresnel Lenses; the corresponding diaphragm of projector is arranged; Fresnel Lenses corresponding rotation diaphragm is arranged; above Fresnel Lenses group, be provided with cover glass, described computing machine is connected with projector and Fresnel Lenses group respectively by controller.

Preferably, above-mentioned multiple projector arranges one week in the horizontal plane, and projector tilts obliquely upward.

Preferably, above-mentioned Fresnel Lenses group 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.

The intelligence suspension bore hole stereoscopic display device 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.

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 intelligence suspension bore hole stereoscopic display device that the utility model provides, the directed Fresnel Lenses 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 Fresnel Lenses rotated and four groups of rotary diaphragms 2 are all placed perpendicular to projector light direction of principal axis.The emergent pupil of projector 1 through rotary diaphragm 2, then passes through directed Fresnel Lenses group 3 emergent pupil into strips.Projector 1 horizontal positioned one week, directed screen and rotary diaphragm 2 carry out synchronous rotary, the observation domain of system is the seamless spliced cone space of a series of bar shaped emergent pupil, when observer 6 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 intelligence suspension bore hole stereoscopic display device 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 Fresnel Lenses group 3, be positioned at the top of spin orientation Fresnel Lenses group 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 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.
