Embodiment Construction

[0015] The present invention will be further detailed below in conjunction with the embodiments and with reference to the accompanying drawings: see figure 1 The 360° three-dimensional display device based on the adjustable three-dimensional image space is composed of a display screen 1, a lens array 2, a holographic directional scattering screen 3, and a polyhedral reflector 4. On the optical path, the display screen 1 displays a two-dimensional image, which is imaged on different areas of the holographic directional scattering screen 3 through the lens array 2, and is reflected by the polyhedral reflector 4, and finally people are in a 360° horizontal direction on a circle. You can see a three-dimensional image above. When people are in different directions, different sides of the three-dimensional image can be seen from different reflecting surfaces of the polyhedral reflector 4. At the same time, the three-dimensional images of different sides should be set according to the...

Abstract

An adjustable 360-degree three-dimensional display device based on three-dimensional image space comprises a display screen (1), a lens array (2), a holographic orientation diffuser screen (3) and a multi-face reflector (4), wherein the display screen (1) displays a two-dimensional image which is composed of a plurality of sub-images, all sub-images pass through sub-lenses of the lens array (2) respectively and imaged to different areas of the holographic orientation diffuser screen (3) respectively, images of different areas correspond to different reflecting faces of the multi-face reflector (4) respectively, and finally people can see a three-dimensional image on the circumference of the multi-face reflector (4). Adjustment of the physical size of the three-dimensional image is achieved through the adjustment of the imaging relation of the lens array (2). The multi-face reflector (4) has good transmissivity, and therefore the three-dimensional image has good actual vividness and is like a three-dimensional object emerging in the multi-face reflector (4). The adjustable 360-degree three-dimensional display device based on the three-dimensional image space is strong in feasibility, can be used for product display, and can even be taken as a general display platform for three-dimensional images.

Description

【Technical Field】 [0001] The invention relates to a three-dimensional display device, in particular to a 360° three-dimensional display device which is adjustable based on a three-dimensional image space. 【Background technique】 [0002] With the development of three-dimensional display technology, people can no longer be satisfied with the existing two-dimensional image display, hoping to display a three-dimensional image with a three-dimensional effect, so that people can better understand the three-dimensional information of the image. Three-dimensional technology is gradually moving towards commercialization, such as three-dimensional movies. However, the current three-dimensional movies all need to wear glasses, which is very inconvenient for the viewer. In order to realize naked-eye 3D display technology, many methods have been proposed. According to the observable range, it can be divided into flat three-dimensional display technology and peripheral three-dimensional disp...
