And popularization.
The content of the invention
The problem of to overcome current holographic display to exist, the utility model provide itself a kind of visible holographic display
Device, can both be provided for holographic display interaction may, be line holographic projections technology application increase practicality and interest,
Also achieve summary, the cost degradation that interactive holographic display makes.On this basis, the utility model also has and taken
The advantages of band is convenient, folding storage, device is set to prevent take up excessive space when on the shelf.
The method that the utility model solves its technical problem underlying is to combine mirror image, holographic imaging and motion capture
Get up, by observer's mirror image and the interaction of holographic imaging, reach and realize a kind of itself simple and feasible visible holography
The purpose of display device.
The device includes LCDs, Bright View, holographic imaging screen, central shaft, camera, four positioning strips and eight
Individual anchor point.
LCDs, holographic imaging screen are identical with Bright View length, width, respectively have side connection on center shaft, its
With central shaft to be fixedly connected, holographic imaging screen and Bright View are hinged middle LCDs with central shaft；Camera is arranged on mirror
At directly over face；Respectively there is a positioner side of holographic imaging screen, and described positioner is hinged on entirely including one end
Cease the first positioning strip and the second positioning strip of the first anchor point of imaging screen side, the free end of the first positioning strip optionally with
Second anchor point of Bright View side or the 4th anchor point of holographic imaging screen side releasably connect, the second positioning strip from
By hold optionally with the 3rd anchor point of LCDs side or the 4th anchor point of holographic imaging screen side releasably
Connection.
Preferably, LCDs and Bright View are mutually perpendicular to, when free end and the Bright View side of the first positioning strip
Second anchor point is connected, while the free end of the second positioning strip is connected with the 3rd anchor point of LCDs side, holography into
As screen and LCDs and Bright View are all into 45 degree of angles.
When the present apparatus is in use state, holographic imaging screen and Bright View are rotated, device is opened, by the first positioning strip
Vacant aperture connects the second anchor point, the vacant aperture of the second positioning strip is connected into the 3rd anchor point, now Bright View is set
Put in the position vertical with LCDs, holographic imaging screen is arranged on the position into 45 degree of angles with LCDs.
When the present apparatus is on the shelf, in order to save space, holographic imaging screen and Bright View are rotated, retracting device, by the
Aperture of one positioning strip away from holographic imaging screen connects the 4th anchor point, and aperture of second positioning strip away from holographic imaging screen also connects
Connect the 4th anchor point, the first positioning strip and the second positioning strip is overlapping collapses in holographic imaging screen both sides, whole device is with notebook
The state closed up collapses, and saves placement space.
The use principle of the device is：When the present apparatus is under use state, LCDs playing video, observer
The reflecting surface of Bright View is faced, it was observed that the hologram that image reflects to form through holographic imaging screen, while pass through holographic imaging
Screen sees oneself mirror image in Bright View, and two images are overlapped, produces also very also unreal holographic display effect.Take the photograph
As the picture in head seizure image pickup scope, the movable information such as skeleton, gesture and face in picture is followed the trail of, and according to pre-
The animation first set is made a response to these motions, is generated corresponding video pictures and is shown on LCD screen.Due to from shooting
The time that head catches picture to generation video is extremely short, forms the effect of hologram and observer itself image immediate interactive,
So as to reach the purpose that observer interacts with hologram.
The utility model has the advantage of：The combination of line holographic projections and mirror-reflection imaging based on imaging film, for observation
Person provides a kind of enhancing display effect of virtual reality fusion；Motion tracking based on camera, for user provide with virtually
Interaction effect between hologram；The design of positioning strip and anchor point, can fast folding this equipment, be easy to carry about with one.
