Abstract
The invention discloses a micro-grating sub-pixel three-dimensional optical image, which is formed by pixel array structures arranged on a plane, and the image contains sub-visual angle image information of multiple visual angles. The micro-grating sub-pixel three-dimensional optical image is characterized in that: each pixel consists of a plurality of sub-pixels; each sub-pixel corresponds to an image of one visual angle at the pixel; each sub-pixel is a grating image unit; and the stripe orientation of each grating image corresponds to each visual angle, and the periods of stripes represent color information. The making method comprises the following steps of: designing three-dimensional diffraction optical image data; designing a template image with a sub-pixel stereoscopic structure; generating a voxel image according to the image data and a template; and micro-shrinking a photoetching sub-pixel stereoscopic image unit to obtain a three-dimensional diffraction optical image formed by the sub-pixel stereoscopic unit. By the making method, three-dimensional images can be outputted in a digitized mode.
Description
technical field [0001] The invention relates to an optical image and its design and implementation method, in particular to a three-dimensional digital image with multi-view information and its production, which can be used in the fields of three-dimensional display, three-dimensional printing and virtual reality. Background technique [0002] People's perception of the objective environment is always obtained through vision, hearing, touch, smell, and taste. Realistically simulating and reproducing these on-the-spot feelings is one of the important research topics of modern science and technology. Through the stereo system, people can hear the feeling of the scene, and the stereo technology has been developed to a higher technical level. Stereo vision technology still needs technological breakthroughs in order to achieve practical applications. Stereoscopic vision technology includes stereoscopic image and stereoscopic video, and what the present invention relates to is st...
