Abstract

The invention relates to a surround-view three-dimensional display device based on multi-projectors and a reflective scattering screen, belonging to the field of three-dimensional display. Including: reflective scattering screen and multiple projection devices; connection relationship: multiple projection devices are arranged along the circumference in space, and the projection device working at each moment projects onto the reflective scattering screen; this device utilizes the rotation of the reflective scattering screen and multiple The synchronous and alternate work of the projection device makes the images of the left and right eyes of people come from the belt-shaped observation area formed by different image sources, so that the left and right eyes see different images respectively, and a three-dimensional image can be synthesized by the human brain.

Description

technical field [0001] The invention relates to a surround-view three-dimensional display device based on multi-projectors and a reflective scattering screen, belonging to the field of three-dimensional display. Background technique [0002] In many fields such as entertainment, scientific research, medical treatment, military affairs, education, etc., three-dimensional display devices have been widely used due to the advantages of displaying objects over two-dimensional images. Most of the commercial 3D displays are now mainly based on glasses-type parallax display technology, including shutter-type and polarized-type. Due to the inconvenience and unnaturalness of wearing glasses, naked-eye three-dimensional display devices have been widely developed. Most of the grating-type naked-eye 3D display devices widely used at present are 3D displays on flat screens. Due to the small number of disparity maps and the shape of the flat screen itself, the observation range is limited...
