On-site reproduction holographic projection display system

Abstract

The invention discloses a holographic projection display system for scene representation, relating to the technical field of 3D display. The holographic projection display system comprises a three-dimensional display module, an auxiliary light source, a projection screen, a motion following drive module, a human eye recognition module and a processor, wherein the processor controls the three-dimensional display module to project a picture on a projection screen; the light of the auxiliary light source is projected to the projection screen for picture modulation to form a hologram, so that a 3D picture can be watched; the human eye recognition module is capable of positioning the position of human eyes, the processor controls the motion following drive module to act through analysis and processing of the processor, the motion following drive module is connected with the three-dimensional display module or the projection screen, and controls the three-dimensional display module and the projection screen to move, and the human eyes and the three-dimensional display module are in a mirror image position relative to the projection screen, so that the condition that a person can receive the clear 3D picture during movement is ensured. The overall projection system is simple in structure, small in occupied space and low in production cost, and meanwhile, the effect of watching the 3D image through naked eyes can be achieved.

Description

technical field [0001] The invention relates to the technical field of 3D display, in particular to a holographic projection display system for on-site reproduction. Background technique [0002] 3D display technology can provide depth information to users in addition to displaying flat images, so 3D technology has become more and more popular in recent years. At the present stage, the mainstream 3D video provision scheme mainly uses the principle of parallax to make people's left and right eyes receive corresponding stereoscopic image pairs, and then forms a 3D (3Dimensions) stereoscopic effect in the brain. This method can provide users with acceptable picture quality at the cheapest cost, but this 3D is not a real stereoscopic display, but a pseudo 3D technology. Since the actual image it provides is on the screen, but the synthetic pseudo 3D image appears to be outside the screen, this way of viewing for a long time will bring obvious discomfort.
