Abstract

The invention discloses a high-visual angle resolution 360-degree visual field three-dimensional displaying device. The device comprises an LED (light-emitting diode) light source, an illumination optical system, a space optical modulator, a projection optical system, a combined directional scattering screen, a rotating device, an image storage control module, a rotation detecting module and a light source pulse driving control module. The invention also discloses a method for realizing high-visual angle resolution 360-degree visual field three-dimensional displaying. The LED light source is matched with the rotation of the combined directional scattering screen in a pulse illuminating way through the light source pulse driving control module, high-density visual angle scanning is realized by using minimal deviation of the scattering direction of each directional scattering sub-screen, 360-degree visual field three-dimensional displaying with high visual angle resolution is realized, the quality of a three-dimensional display image is improved, and the habit of nature observation of human eyes is better satisfied.

Description

technical field [0001] The invention belongs to the technical field of three-dimensional display, and in particular relates to a three-dimensional display device and a display method with a high viewing angle resolution and a 360° field of view. Background technique [0002] Various depth cues such as binocular parallax, motion parallax, and accommodation allow people to have a three-dimensional perception of objects. Three-dimensional display technology has good application prospects in many fields such as biomedicine, architectural design, scientific display, film and television entertainment, video communication and commodity advertisement. Due to the small difference in the spatial position of the two eyes of a person, there are certain differences in the scenes that the two eyes can see. It is precisely because of this small difference that the human brain processes it and produces depth perception. Also known as stereo perception. At present, 3D display technologies ...
