Embodiment Construction

[0015] The present invention will be further described below in conjunction with accompanying drawing:

[0016] Such as figure 1 Shown is a schematic diagram of an embodiment of the digital planetarium of the present invention. It includes a dome 1, a fisheye lens 2, a projector 4 and a computer 5; the fisheye lens 2 is located directly below the dome 1, and projects the light emitted by the projector 4 onto the dome 1; the computer 5 is connected with the projector 4, It is used to control the projection of the projector 4 to the dome 1.

[0017] Such as figure 2 As shown, it is a schematic diagram of an embodiment of the multi-projector superposition mode of the digital planetarium of the present invention. and figure 1 Compared with the digital planetarium in , it includes a plurality of fisheye lenses 2 and a plurality of projectors 4; a computer 5 is connected with a plurality of projectors 4, and is used to control the projection of a plurality of projectors 4 to th...

Abstract

The invention discloses a digital planetarium which is characterized by comprising a dome (1); a projection machine (4) is arranged below the dome (1); the image input end of the projection machine (4) is connected with the image output end of a computer (5); and the image output end of the projection machine (4) is connected with a fish-eye lens (2) arranged right under the dome (1). Due to the adoption of a projection technique, all astronomical phenomenon and astronomical popular science teaching programs can be played; the digital planetarium is simple in structure and low in price, not only can be used for demonstrating various starry sky motions which can be demonstrated by an optical planetarium, but also can be used for demonstrating almost all astronomical phenomena which cannot be simulated and demonstrated in real time by the optical planetarium. In addition, the digital planetarium is also a dome cinema system and can play dynamic digital dome programs.

Description

technical field [0001] The invention relates to a planetarium, in particular to a digital planetarium with projection display. Background technique [0002] At present, the planetariums of domestic schools and science and technology museums mostly use optical planetariums. The main body of the optical planetarium is a hollow ball with a built-in light bulb, which presents each star with a pinhole, simulating the daily movement. After adding various planetarium projectors, images of the sun, planets, satellites, and nebula galaxies can be played. Demonstrating coordinate lines, constellations and other astronomical knowledge requires more projection equipment. Limited by the structure, it is very difficult to show celestial phenomena and other dynamic scenes other than the starry sky. In addition, the operation of the optical planetarium is also very complicated, and the maintenance is also troublesome. There are problems of single function, complex operation and few film ...
