Problems solved by technology

Holographic three-dimensional display tries to reconstruct the light wave of the object that the eyes can get, so that the realistic image of the object can be seen even if the object is not in the original place. The biggest problem at present is that the reproduction of three-dimensional light field information is relatively complicated, which is not convenient for large-scale application
They are based on planar images, with low resolution in the stereoscopic viewing area, small stereoscopic viewing angles, and a small number of visible points

Abstract

The invention relates to a system and a method for full-angular parallax stereoscopic imaging based on single DLP (digital light processing) projection. The system comprises an image acquisition sub-system and a full-angular parallax stereoscopic imaging sub-system, wherein the image acquisition sub-system comprises a camera and a low-speed turntable; the full-angular parallax stereoscopic imaging sub-system comprises a computer, a DLP projector, a high-speed turntable, a directional diffuse screen, a protection bracket, a Hall device and a strong magnet; and the camera, the DLP projector andthe Hall device are connected to the computer. The method comprises the following steps: using the image acquisition sub-system to acquire a video signal; converting the video signal into digital video data through an image acquisition card; transmitting a full-angular parallax stereoscopic image to the DLP projector by the computer through a video line and then projecting the image to the directional diffuse screen for imaging; and calculating a motor speed by the computer according to a level signal of the Hall device, thereby providing a synchronizing signal to the DLP projector and realizing the accurate uniform of the parallax stereoscopic image and physical angle. The system and method provided by the invention have the advantages that the cost is low, the implementation is easy, the running is reliable, and the stability is high.

Description

technical field [0001] The invention relates to a parallax stereoscopic display system and method, in particular to a full-angle parallax stereoscopic imaging system and method based on single DLP (Digital Light Projector, digital light projection) projection, and belongs to the technical field of three-dimensional image display. Background technique [0002] The objective world is a three-dimensional space with three dimensions. Since the birth of display devices, in order to truly reproduce the objective world, people have never stopped researching on stereoscopic display technology. The so-called three-dimensional display refers to the ability to display the image depth (third dimension) effect, just like we see the real world, it is three-dimensional. Stereoscopic display technology can be divided into naked-eye stereoscopic display technology and non-naked-eye stereoscopic display technology according to whether to add stereoscopic glasses. [0003] The current naked-...
