Problems solved by technology

The disadvantage is that the opacity of the black stripes in the grating reduces the brightness of the image; when the size is large, the crosstalk phenomenon is obvious; when the number of viewpoints is large, the grating is prone to diffraction effects, etc.
The number of viewpoints realized by the parallax barrier is limited, and it is rarely used in projection multi-view autostereoscopic display systems

Embodiment Construction

[0035] The projected high-resolution multi-view autostereoscopic system includes: an optical display screen 1, an array of n*m projectors 2, a computer cluster rendering subsystem 3, and a high-resolution camera 4 for geometry and brightness correction.

[0036] Wherein, the n*m ​​projector array is divided into m groups of single-viewpoint projector groups, and each group has n projectors. Each group of single-viewpoint projectors uses r*s (r rows, s columns) to combine and display one viewpoint image of the scene. That is, each group of projectors is combined to display a high-resolution large display area, which is composed of r rows and s columns of sub-display areas, and each projector displays one of the sub-areas, and n=r*s. m groups of projectors display m viewpoint images of the scene, and their display areas overlap each other. The cluster rendering system drives the n*m ​​projector array to simultaneously project m viewpoint images of the scene on the optical scree...

Abstract

The invention relates to a projection type high-resolution multi-view auto-stereo display system which is characterized by comprising an optical display screen and an array with n*m sets of projectors, n is row, m is line, and the projection type high-resolution multi-view auto-stereo display system also comprises a computer cluster rendering subsystem and a camera used for geometry and brightness correction. The projector array is divided into m sets of single-view projector groups, and each set of single-view projector group couples and displays a high-resolution large display area by n sets of projectors by a combination display wall technology. Each set of projectors display one view image of a scene, and m sets of projectors display m view images of the scene at the same time, thereby realizing the multi-view panoramic stereo effect.

Description

technical field [0001] The invention relates to a projection type high-resolution multi-viewpoint autostereoscopic display system, in particular to related technologies such as a projector array space position arrangement method and optical screen production in the projection type high-resolution multi-viewpoint autostereoscopic display system. Background technique [0002] Autostereoscopic display technology refers to a three-dimensional stereoscopic display technology that does not need to wear auxiliary equipment such as stereoscopic glasses. It solves the discomfort such as nausea and dizziness caused by wearing an accessory device. [0003] Autostereoscopic display technologies mainly include liquid crystal autostereoscopic display technology and projection autostereoscopic display technology. Liquid crystal autostereoscopic display systems are currently limited in screen size and offer a limited number of viewpoints. The projected multi-view autostereoscopic display ...
