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 for a 360° field of view with high viewing angle resolution. Background technique [0002] A variety of depth cues such as binocular parallax, motion parallax, and accommodation make people have 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 commercial advertising. Due to the slight difference in the spatial position of the two human eyes, there is a certain difference in the scene that the two eyes can see. It is precisely because of this slight difference that the human brain processes it and produces depth perception. That is stereo perception. At present, three-dimensional display technology is...
