Problems solved by technology

However, the screen of this technology is composed of multiple side screens with a certain angle. The image is projected onto the side screens with a certain angle. The intersection of two adjacent side screens will cause the image to be sharp and affect the viewer's vision. Effect; the projection system composed of the screen adopts the rear projection method, and the projector is located behind the screen, resulting in a large footprint of the entire projection system, which can only accommodate a small audience

Embodiment 1

[0035] Embodiment one, such as figure 1 , as shown: a panoramic screen, in order to prevent the image from being projected onto the screen to form a sharp transition effect, the panoramic screen surrounds and forms part of the side of the inverted circular platform, wherein, part of the side of the inverted circular platform includes: the generatrix of the circular platform rotates 120°-330° to form part. In addition, in order to maintain the integrity of the image, try to avoid the picture effect caused by the splicing line of the screen, and improve the perception, the panoramic screen adopts an overall seamless structure. Combined with the actual visual effect, which includes the viewer's observation point, the inclination angle of the viewer's head, and the range of the viewer's viewing angle, the taper of the circular table is 5°-12°, preferably 5°, and the height is 1800-5000 mm, preferably 2800 mm. mm, the radius of the bottom surface is 2500-5000 mm, preferably 3050 m...

Embodiment 2

[0036] Embodiment 2: Different from Embodiment 1, the panoramic screen surrounds all sides forming the inverted circular frustum.

[0037] Next, the present invention describes the panoramic screen system in detail through a specific embodiment, such as figure 2 , as shown in:

[0038] A panoramic screen system is composed of the above panoramic screen and a plurality of projectors 3. In order to save the floor area of ​​the entire panoramic screen system, the projectors 3 are placed above the panoramic screen. Through the inverted screen and light path, the audience can observe closer to the screen. In other words, it can accommodate more audiences under the same area.

[0039] The above-mentioned panoramic screen is adopted in the panoramic screen system, so that the image projected by the projector 3 onto the panoramic screen has a smooth transition, no break point, and a good visual effect.

[0040] In order to facilitate the adjustment of the placement position of the ...

Abstract

The invention relates to the field of image pickup, in particular to a full-view screen, a full-view screen system and an operating method thereof. The full-view screen surrounds to form the entire or a part of the side face of an inverted round table. The full-view screen system comprises a full-view screen and a plurality of projectors, wherein the projectors are positioned above the full-view screen. The operating method of the full-view screen system comprises the following steps of: A, arranging the full-view screen vertically to construct an inverted round table; and B, arranging the projects above the full-view screen. Audiences can get closer to the screen for observing. In other words, more audiences can be accommodated under the condition of equal area.

Description

technical field [0001] The present invention relates to the field of photography, in particular to a panoramic screen, a panoramic screen system and an operating method thereof. Background technique [0002] The currently used panoramic projection technology usually adopts Cave Automatic Virtual Environment (CAVE for short). CAVE is an immersive virtual reality display system based on projection, which is characterized by high resolution, strong immersion, and good interactivity. The principle of the CAVE immersive virtual reality display system is relatively complicated. It is based on computer graphics and perfectly integrates high-resolution stereoscopic projection display technology, multi-channel visual synchronization technology, audio technology, and sensor technology. Thus, a fully immersive virtual environment surrounded by three-dimensional projection screens for multiple people is generated. However, the screen of this technology is composed of multiple side scre...
