Description

180-degree holographic and L-screen naked eye 3D immersive space

Technical Field

The utility model belongs to the field of multimedia space application and display, and particularly relates to a 180-degree holographic and L-screen naked eye 3D immersive space.

Background

180-degree holography: the 180-degree holography is one of projection technologies, and does not need to wear the stereoscopic special effect of 3D glasses. The delicate objects float in an endless space and seem to be within reach. The holographic illusion presents a stereoscopic effect in the air through complex optical action and is lifelike. The novel exhibition hall is mainly used for exhibition, news-publishing, large-scale meeting lease exhibition, museum and other exhibition halls for fixed installation and use.

Immersive projection: the most important device for immersive projection is the projector. In terms of projection principle, projectors on the market at present are largely classified into LCD projection and DLP projection. The LCD projector mainly uses the photoelectric effect of liquid crystal to affect the optical properties of the liquid crystal cell by affecting the transmittance or reflectance of the liquid crystal cell, so as to generate images with different gray levels and colors. DLP projection mainly uses a digital light processor as an imaging device, and has a main principle that image signals such as characters and images are digitally processed and then projected through an optical lens. The immersive projection is different from the two projection technologies, is a projection system expanded based on a holographic stereoscopic projection technology, is a 3D image display technology for recording and reproducing the original state of an object by using the principle of light diffraction, can show a 3D image effect in air or on a three-dimensional lens made of a special material, and is also called as a virtual image technology. The device can project images on walls, screens, floors or even roofs, visitors can enjoy the scenes when sitting, standing or lying, and the visitors feel in the device;

the holographic projection is that the screen display picture is refracted and displayed on a medium suspended in the half-air of a real scene to form an image through the combination of an optical effect and equipment, so that the three-dimensional effect is presented in the air, and the holographic projection has the advantages that a picture object presents a 3D three-dimensional effect and has no space effect; the defect is that corresponding image video resources need to be manufactured on different devices to achieve the 3D stereoscopic effect.
