Holographic projection is also called virtual imaging, and the principle of naked-eye 3D is the same, the projection technology is combined with 3D animation, and the screen is used as the projection carrier. The 3D dynamic video is projected onto the screen through the projector, and a dreamy and gorgeous picture can emerge. The screen has good perspective, and it seems to be imaged in the air from a distance. Combined with the 3D effect of 270-degree stereo imaging of the banquet hall, it can achieve double visual effects. In the holographic banquet hall, holographic imaging can be used for large-scale stage performances, various conferences, weddings and so on.
