Abstract
The utility model discloses a refracting spherical inner projection device which belongs to field of scientific research and teaching experiment of celestial body simulation. A fish-eye lens which is fixed on the base of the a projector is positioned on the bottom end of a spherical inner projection screen, which is also pointed into an opening positioned at the bottom of the spherical inner projection screen; and the projector is connected with a video resource and a man-machine conversion device. The utility model is characterized in that the projecting angle is over 100 degrees so that images can be projected onto the spherical inner projection screen through the fish eye lens and viewed all around. The utility model is suitable for advertising or exhibiting knowledge about the earth, the satellite, the planet, the earthquake, the sea, the atmosphere, the sun, etc through animations or pictures in a spatial scientific center, an astronomical observatory, a seismological bureau, an aeronautic and space administration, a school, a museum, etc.
Description
Technical field
The utility model belongs to the scientific research and the teaching test device field of simulating celestial body, the spherical inner projection device of particularly a kind of refraction type.
Background technology
The scientific research of existing simulation celestial body and teaching test device have only the planetarium, just there is similar equipment in the space science research centre, equipment is huge, common adult will wonder some knowledge of celestial body aspect, relevant universe with child, only going to the planetarium to buy tickets sees a film, very saw a few isolated words and phrases, want then some difficulty of overall understanding to 20 minutes.Current small-sized teaching test device is also rare.
Summary of the invention
The purpose of this utility model is to provide a kind of refraction type spherical inner projection device at the deficiencies in the prior art.It is characterized in that, an opening is set in the lower end of spherical inner projection screen 1; Fixing fish eye lens 2 in the projector on the base 63, fish eye lens 2 inserts in the opening of spherical inner projection screen 1 lower end, and the input socket of video source 4 connects human-computer interaction device 5, and the output of video source 4 connects projector 3 by signal cable.
Described fish eye lens 2 inserts in the opening of spherical inner projection screen 1 lower end, and its junction is a light-shielding structure.
Described fish-eye projection angle is 100 degree＜θ＜190 degree.
Described video source comprises DVD player, VCD player or computer.
Described human-computer interaction device is the human-computer interaction interface of being made up of touch-screen, mouse, keyboard, button.
Described spherical inner projection screen is the two-sided coarse resin material of thermo forming.
The beneficial effects of the utility model are to utilize fish eye lens that the projection angle of projector is become about 180 degree, can make to the spherical inner projection screen spectators center on screen image projection and view and admire in the scopes of 360 degree.
The spheroid profile utmost point of this spherical inner projection device meets the external form of universe celestial body, aspect the celestial body of performance universe very big advantage is being arranged, as long as describe such as: the slice, thin piece of celestial bodies such as planet, satellite, the sun displays with this interior pitching, celestial body that work is taken off exactly, the secret to people displaying universe true to nature.
This product can be used in the space science center widely, in astronomical observatory, seismological bureau, places such as NASA, school, museum, by manifestation modes such as animation and images, show contents such as the relevant earth, satellite, planet, earthquake, ocean, atmosphere, the sun, it can also show the user as required and wants all the elements of showing in addition.The widespread use of interior pitching will have been given play to vital role in scientific research and education sector.
