Abstract

The invention discloses a true color 360 degrees three-dimensional display device based on a high-speed projector. The true color 360 degrees three-dimensional display device based on the high-speed projector comprises a light emitting diode (LED) light source group, an illumination optical system, a spatial light modulator, a color combination prism, a projection lens, a directional diffuser screen, a rotary device, rotation detection module and a light source drive control module. The invention further discloses a true color 360 degrees three-dimensional display method based on the high-speed projector. The true color 360 degrees three-dimensional display device and the method based on the high-speed projector conducts gray binary encoding on the light intensity of the LED light source through the light source drive control module and keeps the LED light source in sync with the rotation of the directional diffuser screen, the binary images with different gray scales are projected to the rotary directional diffuser screen in a timing sequence by the high-speed projector so that the 360 degrees view field three-dimensional display is achieved. The true color spatial three-dimensional display which can be seen from multiple perspectives by a plurality of people with naked eyes simultaneously is achieved, the image quality of the three-dimensional display is improved and the requirement on the frame frequency of the spatial light modulator is reduced.

Description

technical field [0001] The invention belongs to the technical field of three-dimensional display, and in particular relates to a high-speed projector-based true-color 360° three-dimensional display device and method. Background technique [0002] Vision is the main way for humans to understand the world and nature, and most of the information obtained by humans comes from vision. For a long time, the main means of expressing visual information is still two-dimensional. Traditional two-dimensional display technology loses the depth information of the real physical world, which seriously hinders human perception of the objective world. Human beings are born spatial thinkers, how to realize the three-dimensional display of real space has always been the goal that people are striving for. At present, 3D display technologies are mainly divided into four categories: stereoscopic 3D display technology, auto-stereoscopic 3D display technology, volumetric 3D display technology, lig...
