Abstract

The invention discloses a 360-degree free stereo three-dimensional display speaker based on face detection. The three-dimensional display speaker includes a 360-degree face detection module, a micro projector module, a transmission projection imaging optical system or a reflection projection imaging Optical system and cylindrical holographic directional scattering screen; the 360-degree face detection module is arranged around the outside of the three-dimensional display speaker, the cylindrical holographic directional scattering screen is arranged in the center of the three-dimensional display speaker, and the transmission projection imaging optical system and the micro-projector module are sequentially arranged under the cylindrical holographic directional scattering screen. The 360-degree free stereo three-dimensional display speaker based on face detection provided by the present invention does not require special glasses for users, and can watch 3D scenes in any horizontal direction and certain vertical direction at an appropriate distance, and has the advantages of portability and the like.

Description

technical field [0001] The invention relates to the field of three-dimensional display, in particular to a 360-degree free stereoscopic three-dimensional display sound box based on face detection. Background technique [0002] By the end of the 15th century, Leonardo Da Vinci discovered that people can perceive three-dimensionality and depth when viewing parallax images. Currently popular 3D display methods include holographic 3D display, parallax 3D display, integrated imaging 3D display, and light field 3D display. [0003] Holographic display is an ideal 3D display method, but the performance of existing equipment cannot carry the excessive amount of information of holographic display, and it is difficult to achieve high-resolution and dynamic holographic images. [0004] The parallax-type three-dimensional display enables the left and right eyes of a person to see two different two-dimensional images, and the parallax fusion by the brain produces a three-dimensional eff...
