Abstract

The invention relates to a true three-dimensional image display system and a true three-dimensional image display method. The system includes: at least one image source, which generates K field image beams; an optical compression device, which compresses the image beams of each field of view to form H sets of compressed image beams, and each set of compressed image beams includes K columns of image beams, and each set of compression The K columns of image beams in the image beams are respectively the same columns of image beams of K field image beams; the imaging screen has H areas, and each area corresponds to receiving a set of compressed image beams; the optical device includes H imaging units, Each imaging unit shoots K column image beams in the compressed image beams projected into each area of ​​the imaging screen into K fields of view respectively; the optical scanning device guides the image beams in the H sets of compressed image beams respectively to In the H regions leading to the imaging screen, K and H are both integers not less than 1. The invention has the advantages of low cost, low calibration difficulty and clear image.

Description

Technical field [0001] The invention relates to image display technology, in particular to a true three-dimensional image display system and a true three-dimensional image display method. Background technique [0002] The so-called "true three-dimensional display" means that the relative positional relationship between the displayed three-dimensional objects is also truly reflected, forming a true three-dimensional space image, with the surface characteristics of real physical depth and image quality, and the observer does not need any The auxiliary equipment can observe the displayed object from multiple directions and perceive the most realistic and complete three-dimensional information. True three-dimensional display technology fundamentally updates the concept of image display, makes the displayed image lifelike, provides the viewer with complete psychological and physiological three-dimensional perception information, and provides an understanding of the spatial relationshi...
