Embodiment Construction

[0040] Make I-type high-definition 4D pictures.

[0041] Prepare a slit grating with a format of 1200*900mm, a grating pitch of 1.2mm, the grating lines in the vertical direction, and a slit width of 0.08mm, and mount it on the front surface of a transparent acrylic plate with the same format and a thickness of 4mm; prepare a format of 1200* 900mm, grating pitch 0.6mm, grating lines in the horizontal direction, slit grating with 0.2mm slit width, mounted on the rear surface of the acrylic plate. Prepare a flat and rigid RGB color plate with horizontal lines and a width of 0.6mm, and a group of RGB lines with a width of 1.8mm.

[0042] Use the camera to move on the slide rail to shoot stereoscopic images, each group takes 120 pictures, a total of 3 groups of different pictures. The 120*3 images are cropped uniformly, and the non-proportional compression is adjusted to 1000*1500 pixels. After 4D synthesis of all images, the pixel size becomes 120000*4500 pixels. The image is in...

Abstract

The invention discloses the structure and design method of a high-definition 4D raster picture, wherein a novel picture showing device can be provided by combining rectangular gridding, laser typesetting and outputting, colour board developing and orthogonal grating technologies. Clear, lucid, large-size, and non-dazzling stereoscopic slide projector images and stereoscopic video images can be represented by the movement or relative movement of a horizontal raster. The stereoscopic images or stereoscopic advertisements showed by the stereoscopic slide projector have great stereoscopic sense, definition and viewing comfort; the stereoscopic video can show several hundreds of continuously moving stereoscopic images with contents and plots.

Description

Technical field: [0001] The invention belongs to the technical field of optical display, and relates to a structure and a design method of a 4D grating picture. Background technique: [0002] The so-called 4D usually has two meanings, one is a three-dimensional space plus a time axis, which is the case for the 4D grating picture in the present invention; , that is, 4D cinema. The 4D described in this article is a kind of raster image, which contains hundreds of stereoscopic images, and each stereoscopic image is composed of dozens of parallax images. [0003] Stereoscopic images are gradually popularized in industries such as photography, advertising and decoration due to their advantages of freedom of viewing, strong stereoscopic effect and good adaptability. Stereoscopic pictures are usually composed of stereoscopic gratings and stereoscopic images. Stereoscopic gratings can be slits or lenticular gratings. Stereoscopic images are new images formed by resampling a series...
