Pitching multi-view-based panorama viewing field three-dimensional display device

Abstract

The invention discloses a pitching multi-view-based panorama viewing field three-dimensional display device, comprising a cylindrical LED scan screen, a diaphragm array or a lenticular lens array, a limited optical element and a rotating device. The cylindrical LED scan screen, the diaphragm array or the lenticular lens array and the limited optical element are placed in sequence from the inside to the outside of the device. The cylindrical LED scan screen consists of a plurality of LED arrays, wherein the LED arrays are driven to rotate by the rotating device to display the whole cylindricalimage. Light of all pixels of the cylindrical LED scan screen is divided into a plurality of pitching visual areas in the vertical direction through the diaphragm array or the lenticular lens array, and the light in the horizontal direction of all pixels scans in different illuminating directions through the rotating limited optical element. The device controls light in horizontal direction and vertical direction of all LEDs, realizes pitching multi-view three-dimensional images in the vertical direction through scanning in 360 degrees, and is convenient for more people viewing in 360 degreesand different height positions.

Description

technical field [0001] The present invention relates to a three-dimensional display device, in particular to a three-dimensional display device with a panoramic field of view based on pitching and multi-view angles. Background technique [0002] The difference between three-dimensional display and two-dimensional display is to bring visual depth perception to the viewer through various methods, so that it can naturally or unnaturally obtain the third-dimensional information in the picture. For the viewer, there is a difference between true three-dimensional and false three-dimensional (or quasi-three-dimensional). The development of 3D display technology has produced a large number of achievements today, which can be roughly divided into holographic 3D display, volumetric 3D display, and stereoscopic 3D display. Holographic technology can produce very realistic spatial effects, but it requires high-resolution spatial light modulators and ultra-high-speed data processing sys...

AI Technical Summary

Problems solved by technology

But like most stereoscopic 3D display technologies, it cannot provide 3D information in the vertical direction, that is to say, when the human eye moves up and down, the content seen is the same, which greatly limits the application of stereoscopic 3D display. Application, the present invention solves this problem very well, and realizes the three-dimensional display of the correct view of vertical different height viewpoints
