TECHNICAL FIELD

The present invention relates to a hologram stage setting, and more specifically, to a hologram stage setting that enables performance in a reality environment where reality and virtuality are fused.

BACKGROUND ART

Recently, performance of musicals and the like tends to increase in a reality environment that connects reality and virtuality in a situation where market demand for realistic contents is increasing.

A hologram stage setting in the related art for performance in the reality environment is illustrated in FIG. 1. Referring to FIG. 1, in the hologram stage setting in the related art, a performer 1 stands on a stage and a foil screen is installed at an angle of 45° in front of the performer 1. Further, a reflector 30 is installed on the lower side of the foil screen and a projector 20 for projecting images to the reflector 30 is installed at the upper side of a stage setting.

Accordingly, in the case of using the hologram stage setting in the related art, a 3-dimensional image is implemented through floating type indirect projection of projecting an image 2 from the projector 20 to the reflector 30 and reflecting the image 20 to project an image 3 even onto the foil screen.

However, in hologram stage device in the related art described above, since the foil screen needs to be installed at an angel of 45°, there is a problem in that a large installation space needs to be secured, and since many additional structures such as an iron frame 10 need to be installed, there is a problem in that a special stage needs to secured during performance.

In addition, since the foil screen depends on imported goods, there is a problem in that the costs are increased when forming the hologram stage setting.

Further, in the case of the foil screen, there is a problem in that it is difficult to implement high-resolution images.

Further, in the case of the foil screen, there is a problem in that the durability is poor, maintenance is difficult, and repair is impossible.

Throughout the specification, unless explicitly described to the contrary, the word “comprise” and variations such as “comprises” or “comprising” will be understood to imply the inclusion of stated elements but not the exclusion of any other elements.

Hereinafter, preferred exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a diagram illustrating a hologram stage setting in the related art, FIG. 2 is a diagram schematically illustrating a hologram stage setting according to an exemplary embodiment of the present invention, FIG. 3 is a diagram illustrating a front screen which is applied to the hologram stage setting according to the exemplary embodiment of the present invention, and FIG. 4 is a diagram illustrating a state in which an image is projected to the hologram stage setting according to the exemplary embodiment of the present invention.

Referring to FIGS. 1 to 4, a hologram stage setting according to an exemplary embodiment of the present invention includes a rear screen 100, a lower screen 200, a front screen 300, and a front hologram image projector 400.

The rear screen 100 is a screen which is installed at the rear part of the stage to display a rear background image 110. The rear background image displayed on the rear screen 100 may be projected by a separate projector installed on the upper front side of the stage setting, but may be projected by a projector disposed on the rear surface of the rear screen 100.

The lower screen 200 is a screen which is installed at the lower part of the stage to display a lower background image 210. The lower background image displayed on the lower screen 200 may be projected by a separate projector installed on the upper side of the stage setting, but may be projected by a projector disposed on the bottom of the lower screen 200.

The front screen 300 is a screen which is installed at the front part of the stage to display a front hologram image. The front screen 300 is installed to be erected at an angle of 90° with the lower screen 200.

The front hologram image projector 400 generates a front hologram image to directly project the generated front hologram image to the front screen 300 which is erected at the angle of 90°.

The front hologram image projector 400 is disposed at the upper front side of the front screen 300.

Meanwhile, as illustrated in FIG. 3, the front screen 300 includes a net screen of a grid network structure coated by a ceramic ball lens and a support member 320 which is installed along the edge of the net screen 310 to keep the shape of the net screen.

Herein, the net screen 310 is formed to have a tensile strength of 150 kg/mm2 or more and an elongation of 4% or less by an ultrafine particle ceramic ball coating method. The net screen 310 having the tensile strength and the elongation may have high durability and safety.

Meanwhile, the ceramic ball lens used in the ultrafine particle ceramic ball coating method has a particle size of 70 μm or less, and when the net screen 310 is coated using the ultrafine particle ceramic ball lens, a high-resolution stage image may be implemented by the net screen 310.

Meanwhile, the ceramic ball lens may use a ceramic ball lens having adhesion of 99% or more. When the net screen 310 is coated using the ceramic ball lens having the adhesion of 99% or more, the best image quality may be implemented by the net screen 310.

The net screen 310 may have a reflection coefficient of 3.0 Gain or more. As such, when the net screen 310 is configured with high brightness of the reflection coefficient of 3.0 Gain or more, a higher-resolution stage image may be implemented.

According to the present invention described above, the hologram stage setting is configured to apply a net screen of a grid network structure coated by a ceramic ball lens on the front part of a stage and directly project images, thereby enabling performance without specific limits on general multi-purpose stages instead of special stages, solving high cost problems caused by using a conventional foil screen, implementing high-resolution images, enhancing durability, and performing easy maintenance and repair.

While the specific exemplary embodiments of the present invention have been illustrated and described above, various modifications and changes may be made by a person with ordinary skill in the art to which the present invention pertains without departing from the spirit and the scope of the present invention that are disclosed in the claims.
