Abstract
The utility model discloses a digital planetarium. The digital planetarium is characterized in that the digital planetarium comprises a dome (1), a projector (4) is arranged under the dome (1), the image input end of the projector (4) is connected with the image output end of a computer (5), the image output end of the projector (4) is connected with a fish-eye lens (2), and the fish-eye lens (2) is located just below the dome (1). According to the utility model, the projection technology is adopted, all planetarium astronomy science teaching programs can be played, and advantages of simple structure and low cost can be realized, not only various starry sky movements that can be demonstrated by an optical planetarium can be demonstrated, and but also almost all astronomical phenomena that cannot be simulated and demonstrated by the optical planetarium on a real time basis can be demonstrated. Moreover, the digital planetarium is also a ball screen theatre system which can be used to play dynamic digital ball screen programs.
Description
Technical field
The utility model relates to a kind of space theatre, especially relates to a kind of digital astronomical phenomena Room of Projection Display.
Background technology
At present domestic school and the space theatre of science and technology center use the optics planetarium more.Optics planetarium main body is the hollow ball of a built-in bulb, presents each fixed star with pin hole, the simulation diurnal motion.Add the image that can play the sun, planet, satellite, nebula galaxy after various planetarium projectors, other astronomic knowledges such as demonstration graphed lines, constellation need more projector equipment.Be subjected to structural limitations, it is very difficult wanting to show starry sky astronomical phenomena and other dynamic scene in addition.In addition, the operation of optics planetarium is also very complicated, safeguards also cumbersome.There is function singleness, complicated operation, the problem that film source is few.
Summary of the invention
The purpose of this utility model is to overcome the deficiency that the traditional optical space theatre exists, and a kind of digital astronomical phenomena Room is provided, and adopts the mode of projection to show the demonstration picture on dome, and realizes the content that the optics planetarium can not real time modelling be demonstrated.
The technical solution adopted in the utility model is as follows:
A kind of digital astronomical phenomena Room is characterized in that it comprises dome, and the below of dome is provided with projector, and the image input end of projector connects the output end of image of computing machine, and the output end of image of projector connects fish eye lens, fish eye lens be in dome under.
Described flake border head is provided with a plurality of, and projector also is provided with equivalent amount accordingly, and a plurality of projectors all are connected with same computer.
The utility model also provides another scheme, and is as follows:
A kind of digital astronomical phenomena Room is characterized in that it comprises dome, and the below of dome is provided with many projectors, and the image input end of many projectors connects the output end of image of computing machine, and the output end of image of described projector connects each self-corresponding short-focus lens.
The beneficial effects of the utility model have:
Adopt shadow casting technique, can play all astronomical phenomena astronomical popularization educational programmes, simple in structure, cheap, not only can demonstrate the various motions of the starry sky that the optics planetarium can demonstrate, can also demonstrate nearly all chronometer phenomenon that the optics planetarium can not the real time modelling demonstration.This digital space theatre or a ball screen cinema system, can play dynamic digital ball curtain program in addition.

Embodiment
The utility model is further described below in conjunction with accompanying drawing:
As shown in Figure 1, be a kind of embodiment schematic diagram in the digital astronomical phenomena of the present utility model Room.It comprises dome 1, fish eye lens 2, projector 4 and computing machine 5; Fish eye lens 2 be positioned at dome 1 under, and the light that projector 4 sends is projected on dome 1; Computing machine 5 is connected with projector 4, is used for controlling projection machine 4 to the projection of dome 1.
As shown in Figure 2, be the multi-projector stacked system embodiment schematic diagram in the digital astronomical phenomena of the present utility model Room.Compare with the digital astronomical phenomena Room in Fig. 1, comprise a plurality of fish eye lenses 2 and Duo Tai projector 4; Computing machine 5 is connected with many projectors 4, is used for controlling many projectors 4 to the projection of dome 1; By the superpose image of software control many projectors output of computing machine, the projection that makes it on dome 1 overlaps.
As shown in Figure 3, be the multi-projector splicing amalgamation mode embodiment schematic diagram in the digital astronomical phenomena of the present utility model Room.It comprises a plurality of short-focus lens 3 and Duo Tai projector 4; The image that many projectors 4 will throw separately by short-focus lens 3 respectively is presented at the various piece of dome 1, thereby covers whole dome 1; Computing machine 5 is connected with many projectors 4, is used for controlling many projectors 4 to the projection of dome 1; Control the image of many projectors 4 outputs by computing machine 5 splicing fusion software, the projection that makes it on dome 1 forms complete image.
Other undeclared part that the utility model relates to is same as the prior art.
