Problems solved by technology

However, the current computer hardware cannot meet the requirements of reconstructing the light field information in all directions.
[0006] 2. The conflict between the number of display layers and the display effect
In the past light field display, because the reconstruction method is only optimized for one viewpoint, it can provide little original correct viewing angle information for comparison, and the traditional multi-layer display can bear limited load, so it will lead to small viewing angle and crosstalk. major issues

Embodiment

[0040] Example: A single-pixel reconstruction of an object with 19 viewpoints and a parallax of 1.5 is generated by the algorithm of 2d+depth. The resolution of the original image of the object is 2500*1600, and the obtained viewpoint images are combined by pixels For the sub-image corresponding to a single pixel, the size of the data map obtained is 19*(2500*1600); in terms of screen, three layers of screens are arranged in parallel and aligned, and for each single pixel, selected on each layer of screen 10 pixels to realize the reconstruction of its multi-view information. In terms of image processing methods, machine learning is used to process image data.

[0041] according to figure 1 The coordinate system is set in the same way. When rebuilding the tenth viewpoint in the middle, the schematic diagram of the reconstruction is as follows figure 2 As shown, the screen transmittance at the intersection of the light passing through the backlight layer, the middle layer, an...

Abstract

The invention discloses a naked eye three-dimensional display method based on single-pixel multi-view reconstruction, which comprises the following steps of: firstly, acquiring a series of view images containing object information, and combining the acquired view images into sub-images corresponding to single pixels according to the pixels; and using a multi-layer screen parallel arrangement mode at a display end, a plurality of adjacent pixels on a multi-layer screen are combined together to form a single pixel, and mutually overlapping the brightness and color of the pixels of the multi-layer screen at a plurality of angles. The brightness and color information reconstructed at different angles is consistent with the image information of the sub-image in the corresponding angle direction.

Description

technical field [0001] The invention relates to a naked-eye three-dimensional display method, in particular to a naked-eye three-dimensional display algorithm based on single-pixel reconstruction. Background technique [0002] The current 3D display technology mainly uses binocular parallax and visual persistence effect to enable human eyes to obtain 3D images. However, these display technologies display objects on a two-dimensional plane. The position of the object perceived by the monocular adjustment is on the display screen, while the position of the object focused by binocular convergence is a three-dimensional object in space, which will cause focus convergence. Regulatory conflict. [0003] Multi-layer display is to use multiple display planes to reconstruct the three-dimensional object to be displayed. The depth of field of the multi-layer display exceeds that of the traditional multi-view stereo display, and the viewer will obviously feel that the object is suspen...
