Embodiment 1
[0041] A naked-eye 3D display system, characterized in that it includes a system processor, a cloud server, a user terminal and a display, the user terminal collects and stores 3D image material, interacts with the system processor, and transmits the collected and stored 3D image material, the system The processor receives the 3D image material transmitted by the user terminal, interacts with the cloud server, and transmits the 3D image material. The cloud server receives the 3D image material, and synthesizes the received 3D image material into a 3D model or video through 3D synthesis software. The synthesized 3D model or video is transmitted back to the user terminal through the system processor, and the user terminal displays the 3D model or video on the display by means of push;
[0042] Wherein, the user terminal is loaded with an application APP, and the application APP establishes a network transmission connection with the system processor, and the user terminal performs...
Embodiment 2
[0057] In this embodiment, in order to improve the 3D effect of the model or video on the display, the depth of field function of the display is optimized;
[0058] Wherein, the display is a depth-of-field display, including a liquid crystal screen, a grating, polarizing glass, a depth-of-field device and a polarizing film, and the liquid crystal screen, grating, polarizing glass, depth-of-field device and polarizing film are compounded in sequence.
[0059] In this embodiment, the liquid crystal screen emits image light according to the 3D model or video data. The emitted image light first passes through the grating refraction structure to form a three-dimensional image effect, and then passes through the polarized glass to eliminate interference light and glare, and then enters the depth of field device , through the refraction effect of the depth of field device, the depth of the displayed virtual image formed by the image light is deepened, the image depth is enhanced, and ...
Embodiment 3
[0061] In Embodiment 2, a plurality of obliquely arranged notches are arranged on the front surface of the grating, and the notches are arranged in parallel, and there is one grating unit between two adjacent notches, and the notch and the vertical The angle in the vertical direction is the slope angle of the grating, and the slope angle of the grating is α, and the α is 15-65°;
[0062] Wherein, the grating unit is composed of a transmission arc surface in the middle and reflection surfaces on both sides of the transmission arc surface, and the notch is V-shaped to form reflection surfaces on both sides of the transmission arc surface, and the transmission arc surface is arc-shaped , the included angle between the reflective surface and the V-shaped symmetry line formed by the notch is β, and the β is 5-10.
[0063] In this embodiment, the notches are arranged obliquely to form obliquely parallel grating units, thereby adjusting the columnar arrangement refraction structure o...
