Art personnel all other embodiment obtained without creative labor belongs to the present embodiment protection
Range.
Referring to Fig. 1, solid ball curtain projection system provided in this embodiment, including global formula screen ontology 1, transparent viewing
Platform 2 and multiple projecting cells 3；Wherein, global formula screen ontology 1 includes ball-type frame and is covered on the complete of ball-type frame inner surface
Screen is surrounded, transparent viewing platform 2 is connect across the centre of sphere with the both ends of ball-type frame, and multiple projecting cells 3 are distributed in transparent viewing
2 two sides of platform surround screen fusion projection to complete to realize.
In solid ball curtain projection system provided in this embodiment, by global formula screen ontology 1, transparent viewing platform 2 and throw
3 three parts of shadow unit composition, wherein global formula screen ontology 1 includes the ball-type frame that play fixed supporting role and for projecting
The full encirclement screen of image completes transparent viewing platform 2 by the way that the both ends of transparent viewing platform 2 are separately fixed on ball-type frame
Inside global formula screen ontology 1 across installation, multiple 3 distributing installations of projecting cell are used in transparent 2 two sides of viewing platform
The scheme of multi-channel projection, the projected picture that can be realized each channel completely cover screen curved surface, reach 720 degree of ball-screen projections
Stereo display effect.
As it can be seen that spectators, which are sitting on transparent viewing platform 2, can watch arbitrarily due to the high penetration characteristic of transparent viewing platform 2
The ball-screen projection picture of angle, for example, spectators can pass through the shadowgraph that screen body bottom portion is looked down on transparent 2 floor of viewing platform
Face brings the viewing experience of spectators' full view.
Preferably, door (attached drawing of at least two fans for spectators' disengaging is also provided on the ball-type frame in above-described embodiment
It is not shown), in order to keep surrounding the integrality of screen entirely, screen also is covered on the surface of door, closes shape to be in door
It can combine together with full encirclement screen when state.The purpose that two fan doors are arranged is that spectators can enter transparent viewing platform 2 from Yishanmen
Viewing, and orderly left after viewing from another Yishanmen.
It will receive weather-beaten influence in view of surrounding screen entirely, the global formula screen ontology 1 in above-described embodiment is also
Including for waterproof thermal-insulated outer housing, outer housing is attached to the outer surface of ball-type frame.It can not only by the setting of outer housing
Enough play the role of LP blades protection, but also have the effect of heat and moisture preserving, makes to be in always inside global formula screen ontology 1
The state of constant temperature and humidity, achievees the effect that energy-saving and emission-reduction.
Specifically, the transparent viewing platform 2 in above-described embodiment include fixed bracket 22, slewing (attached drawing is not shown) and

The spectators rided on grandstand gallery 21 at this time can look around the projection of ball curtain all angles with the rotation of grandstand gallery 21, give
Spectators build a kind of visual angle experience of depths space center；In addition, the setting by multiple rows of endless glide can be to grandstand gallery
21 reinforce fixing, and ensure that safety when system operation.
Preferably, referring to Fig. 2, the amount total of projecting cell 3 12, is respectively installed in the two sides of fixed bracket 22 respectively
6, the projection angle of every fixed bracket 22 is different, be allowed to entirely surround screen on projection can complete fusion, this
The stereo display effect of 720 degree of ball-screen projections can be realized in sample.
It is to be understood that since the present embodiment uses the technical solution of multi-channel projection, each projecting cell 3
The projection that lesser dispensing ratio, which need to only be arranged, can meet in ball curtain large area covers, and is compared to list in the prior art
The technical solution of the big dispensing ratio in channel, the present embodiment can effectively ensure that the clarity and brightness of imaging, improve film sight
The visual effect seen.
Please continue to refer to Fig. 2, it is contemplated that the case where spectators will appear dizziness during rotation, above-described embodiment also exists
The edge of grandstand gallery 21 is provided with protective fence 23, to reduce the accidental falling risk of spectators during viewing.
Optionally, fixation bracket 22, grandstand gallery 21 in above-described embodiment, anti-in order to guarantee the viewing effect of spectators
Guardrail 23, great circle endless glide and ringlet endless glide are using high degree glass steel material thoroughly, to reduce the area of visual occlusion.
Referring to Fig. 3, the system in above-described embodiment further includes sequentially connected data storage cell 4, display distribution list
Member 5 and data processing unit 6, the output end of data processing unit 6 are also connect with the input terminal of each projecting cell 3；Data storage
Unit 4 is for storing video image data；Allocation unit 5 is shown for obtaining video image data in real time, and by video image
Data, which are divided into, exports corresponding distribution image data with each projecting cell 3；Data processing unit 6 is used for each distribution image number
The data for projection of output can be identified according to corresponding projecting cell 3 is converted to.In addition, further including being located at number in above-described embodiment
According to the Fusion Edges fine-adjusting unit 7 between processing unit 6 and projecting cell 3, Fusion Edges fine-adjusting unit 7 is used to throw each channel
The edge of shadow image carries out fusion adjustment, and the projected picture in each channel is made completely to cover screen curved surface.
When it is implemented, by the setting of display allocation unit 5, data processing unit 6 and Fusion Edges fine-adjusting unit 7,
Each projecting cell 3 in system can be made to correspond to the specified region for projecting to full encirclement screen according to the data for projection received,
It ensure that different projecting cells 3 are projected on ball curtain with preferable continuity, avoid multiple projection images and go out on ball curtain
The case where now misplacing ensure that the quality of projection imaging.
