Embodiment Construction

[0051] first, figure 1 A schematic structure for carrying out the method according to the invention is shown. It includes a grid 1 composed of pixels x(i,j) on which different viewpoints A(k)—where k=1,...,n and n=6 or n=7— The image part information of - is visible, which also includes a parallax barrier screen 2 arranged at a distance s in front of the grid 1 of pixels x(i,j) in the viewing direction of the observer 3 . Of course, there can also be several observers 3 who obtain a spatial impression according to the method according to the invention.

[0052] also, figure 2 A cross-sectional view of a parallax barrier screen 2 used in the method according to the invention is shown. The parallax barrier screen 2 comprises alternating opaque and transparent parts, wherein the transparent parts correspond according to the invention to stripes that are constrained to substantially straight lines, which are projected in parallel on the parallax barrier screen 2 to the pixels ...

Abstract

The invention relates to the field of spatial representation, particularly to images which are spatially perceivable for simultaneous multiple viewers without auxiliary devices so-called autostereoscopic visualization. The invention addresses the problem of creating a form of autostereoscopic representation based on barrier technology in order to achieve an improved perceptibility for multiple simultaneous viewers. This problem is solved by a method for spatial representation wherein image section data of different viewpoints A(k), where k=1,...,n and n=6 or n=7, are made visible on a grid of image elements x(i,,j), and at least one parallax barrier screen containing alternating opaque and transparent sections is placed at a distance before or behind the grid of image elements x(i,,j). The transparent sections substantially correspond to straight bordered lines which, during the parallel projection of parallax barrier screens onto the grid of image elements x(i,,j), are inclined to at least 21 degrees with respect to the vertical direction of the grid of image elements x(i,,j) and, furthermore, each have the width of at least 1.9 image elements x(i,,j) in the horizontal direction of the grid of image elements x(i,,j).

Description

technical field [0001] The present invention relates to the field of spatial display, in particular to the field of so-called autostereoscopic visualization that can be spatially perceived without assistance and is used by multiple observers at the same time. Background technique [0002] For a long time, various methods have been used in the above fields. A pioneer in this field was Frederic Ives, who in document GB190418672A introduced a system with a "grating" for 3D display. In addition, in the document "Theory of parallax barriers" by Sam H. Kaplan - Journal of SMPTE, Vol. 59, No. 7, pp. 11-21, July 1952 - about using Basic understanding of fence screens. [0003] However, the widespread dissemination of autostereoscopic systems has not been achieved for a long time. It wasn't until the 1980s that 3D systems saw some renaissance due to the computing power and new display technologies now available. In the 90s, the number of patent applications and publications on gl...
