Displaying method, apparatus and system for providing holographic images to a plurality of viewers simultaneously

摘要

A displaying method, a displaying apparatus and a displaying system for providing holographic images to a plurality of viewers simultaneously are provided. The displaying method comprises: tracking motions of M viewers and eye positions thereof, adjusting rotation angles of programmable mirrors allocated to each of the viewers according to the motions of the eye positions of the viewer, it is predefined that each pixel position of the projection screen corresponds to N adjacent ones of the programmable mirrors; modulating a corresponding left-eye 3D image and a corresponding right-eye 3D image according to the tracked motions of the eye positions of each of the viewers and the rotation angles of the programmable mirrors allocated to the viewer, and projecting the left-eye 3D image and the right-eye 3D image onto the projection screen to control optical projections incident to the left eyes and the right eyes of different viewers.

1. A displaying method for providing holographic images to a plurality of viewers simultaneously, comprising:
tracking motions of M viewers and eye positions thereof, where M is a natural number greater than 0; adjusting rotation angles of programmable mirrors allocated to each of the viewers correspondingly according to the tracked motions of the eye positions of the viewer, so that two programmable mirrors in each pixel of a projection screen reflect projection light rays corresponding to a left eye and a right eye to the left eye and the right eye of a corresponding viewer respectively, wherein the programmable mirrors are distributed on a surface of the projection screen to form a programmable mirror array, it is predefined that each pixel position of the projection screen corresponds to N adjacent ones of the programmable mirrors, the N adjacent programmable mirrors corresponding to each pixel position of the projection screen are correspondingly allocated to M viewers in advance, and each eye of each of the viewers is only allocated one of the N programmable mirrors, where N is a natural number greater than 0; and modulating a corresponding left-eye three-dimensional (3D) image and a corresponding right-eye 3D image according to the tracked motions of the eye positions of each of the viewers and the rotation angles of the programmable mirrors allocated to the viewer, and projecting the left-eye 3D image and the right-eye 3D image onto the projection screen to control optical projections incident to the left eyes and the right eyes of different viewers.
