Abstract

The invention relates to a curved surface transmission type 3D light field display system based on a projection array. The system comprises a projection array, a curved surface reflector and a screen; the projection array comprises a plurality of projectors mounted on an arc section bracket, the curved surface reflector is arranged on a light path of the projection array, and light emitted by the projectors is reflected to the screen through the curved reflector and is transmitted to the other side of the screen to be projected to generate a three-dimensional image. According to the curved surface transmission type 3D light field display system, the curved surface reflecting mirror is arranged on the light path of the projection array, the light emitted by the projectors is reflected to the screen and transmitted to the other surface of the screen to be projected to generate a three-dimensional image, the projection distance is increased, the breadth of the display system is expanded under the condition that the occupied area is not increased, the three-dimensional space is fully utilized, the size is small, and the system is convenient to carry and use.

Description

technical field [0001] The invention relates to the technical field of 3D display, in particular to a curved surface transmission 3D light field display system based on a projection array. Background technique [0002] In the 3D display system, 3D display can be divided into two categories: binocular parallax 3D display and true 3D display. Among them, true 3D display refers to using the stereoscopic vision characteristics of the human eye more comprehensively, and truly restoring the perception of the human eye when observing a natural 3D scene. Real imaging. [0003] At present, the 3D light field display technology based on the projection array is a relatively mature true 3D display technology. Wherein, the projector array is arranged in a certain arc, and projects onto a certain area of ​​the screen. Projectors at different positions project images of the field of view in this direction, and the images are fused on the screen, and the light field of the image is diffu...
