Description

Roundness image facility

Technical field

The present invention relates to image facility, more particularly, be about the inwall with spheroid be screen, with the content of the image facility of image projecting on whole sphere.

Background technology

The conception of the roundness image of show image comprehensively in spheroid is just arranged a long time ago, finally show with image.For example, be projected in the domical planetarium of semisphere in the past, may reproduce celestial body, can simulate more real celestial body by adopting spherical screen; In addition, may give spectators with just like the sense of getting drunk of roaming in the heavens.And, even simulate the image of tellurian spontaneous phenomenon, be example with the image of ocean, can make spectators observe seabed and sea simultaneously, may carry out more l-G simulation test near actual phenomenon.

On the other hand, be assumed to be the situation of spherical screen, be different from the semisphere screen that covers the floor, it does not make spectators be positioned at the means of screen, and this is the bottleneck problem that realizes roundness image.As the means that realize, be that the central authorities that the passage of bridge shape runs through spheroid are set in the past, this has become well known fact in patent documentation 1.And from being located at the equatorial perforation window of spheroid, by in the export-oriented spheroid of spheroid discrepancy seat freely being set, this is published by patent documentation 2.

No. 3099132 utility model communique of [patent documentation 2] registration

Yet when hypothesis during with the means of image projecting at whole spheroid, best at present means are to link together by the projection image with a plurality of video frequency projectors to cover whole spheroid.That is to say, many projectors are installed on whole walls of the spheroid that constitutes screen, be projected in the screen scope with the image opposite of each projector, these images couple together and cover whole spheroid.

Can find that by above-mentioned explanation what is called is located spectators in spheroid, mean that simultaneously spectators are arranged in projected light beam; Therefore, must take measures, at projecting method and be provided with on spectators' the support means and work hard, spectators' support means are unlikely to cause blocking projected light beam so that adopt.In the invention that above-mentioned patent documentation 1 is put down in writing, owing to dispose the central authorities that spectators' passage runs through spheroid, therefore, it seems the problem that the image that can produce projection is blocked; But show that in this invention celestial body is not to use projector, but rely on the optical fibre set of exposing luminous component on the screen cover, therefore, the problem that can not occur blocking.And, in the invention that patent documentation 2 is put down in writing, though its prerequisite is to adopt projector to carry out projection, but, owing to only pass in and out the seat from the equatorial perforation window that is located at spheroid, and do not reach near the central authorities of spheroid, therefore, the problem that can not occur blocking.

In addition, in the invention that the patent documentation 1 that is provided with the For Spectators that runs through spheroid central authorities is put down in writing, there is such problem: because the horizontal logical spheroid of passage inside, form the obstacle of visual channel, therefore, be an impediment to that spectators are intent to be watched.

The patent of invention content

The object of the present invention is to provide the For Spectators of setting run through spheroid central authorities, with occlusion issue be limited in Min., the sense of getting drunk brings up to roundness image facility to greatest extent.

For solving above-mentioned problem, at this following two inventions are disclosed.

First characteristic feature of an invention is: be screen at inwall with spheroid, with the roundness image facility of image projecting on whole sphere in, the passage that is provided with bridge shape runs through the central authorities of spheroid, and above-mentioned passage is made up of the bridge grider of floor and support del section this floor, the summit directed downwards.

Second characteristic feature of an invention is: be screen at inwall with spheroid, with the roundness image facility of image projecting on whole sphere in, the passage that is provided with bridge shape runs through the central authorities of spheroid, above-mentioned passage is an opaque section at the central part of floor Width, is transparent part at the position, the left and right sides of Width simultaneously; And hold up transparent guardrail from the left and right sides.

According to first invention, the floor of passage is supported by bridge grider, even dwindle the width and the also unlikely visually-handicap that becomes of thickness on floor, also can not reduce integral intensity; On the other hand, bridge grider adopts the structure of the del section of summit directed downwards, and therefore, the spectators on the passage can obtain not find the visual effect of bridge grider existence.And then, because bridge grider adopts the structure of the del section of summit directed downwards, therefore, can reduce the possibility of the projected light beam that hinders projector as much as possible, help reducing and block.

According to second invention, passage is made opaque section at the central part of floor Width, simultaneously make transparent part at the position, the left and right sides of Width, and the structure of holding up transparent guardrail from the left and right sides, therefore, by the width of opaque section is accomplished Min., can prevent that passage from hindering spectators' sight line, on the other hand, the spectators on the passage may obtain as the sense of getting drunk of floating in spheroid.
