Stereoscopic three-dimensional display based on multi-screen splicing

The invention discloses a stereoscopic three-dimensional display based on multi-screen splicing. The stereoscopic three-dimensional display comprises a two-dimensional display array, a projection lens array, an aperture array and a directional scattering screen. By utilizing a two-dimensional display pixel region segmentation mode and ensuring each display region of the display array to form a projector together with an aperture and a projection lens which is directly in front of the region, all projectors are staggered in vertical direction and project the images corresponding to the display regions to a same position on the directional scattering screen so as to form an image in front of an arc-shaped screen; and the images displayed in each display region are spliced by the images of a three-dimensional object from different visual angles according to a specific segmentation and recombination method. The stereoscopic three-dimensional display provided by the invention has the advantages of achieving high image resolution and high visual angle resolution and realizing observation of an exquisite three-dimensional image with a horizontal parallax. Compared with the single naked-eye display, stereoscopic three-dimensional display provided by the invention has the advantages that the multi-screen splicing settings ensures that the extension of visual angles is realized, and the spatial scale and viewing range of the three-dimensional images are increased.
