Embodiment Construction

[0048] figure 1 A schematic structure for carrying out the method according to the invention is shown. In this case, the parallax barrier screen 2 is aligned at a distance s to the screen 1 with the pixels x(i,j) in a grid of row i and column j, thus forming a screen for the spatial display. Furthermore, a camera 3 generally suitable for recording two-dimensional images can be seen, the output signal of which is fed into the computer 4 here by way of example by means of a frame grabber card. The computer 4 converts the signal accordingly and reproduces it on a monitor 5 .

[0049] The method according to the invention is carried out in the following steps: First, a positioning mark 6 a is temporarily applied approximately on the center or edge of the image area of ​​the screen 1 . The screen 1 with the positioning marks 6a is now recorded by means of the camera 3, wherein, according to figure 1 The positioning mark 6 a is imaged by at least one deflecting mirror 7 and the i...

Abstract

The invention relates to a method for orienting a parallax barrier screen on a display screen with picture elements x(i,,j) in a grid comprising rows i and columns j for the purpose of producing a display screen for three-dimensional representation. This involves the following steps being performed: temporary application of a positioning marker (6a), observation of the positioning marker (6a) by means of a camera (3), relative orientation of the display screen (1), removal of the positioning marker (6a), positioning of the parallax barrier screen (2) in front of the picture area of the display screen (1), display of a test picture, which comprises various views A(k), where k = 1,...,n and n = 6 or n = 7, on the picture elements x(i,,j) with rows i and columns j, observation of the displayed test picture through the parallax barrier screen (2) by means of the camera (3), orientation of the parallax barrier screen (2) in front of the display screen (1). The method according to the invention can be carried out quickly and is therefore suitable for industrial use for the manufacture of display screens for three-dimensional representation.

Description

technical field [0001] The invention relates to a method for aligning a parallax barrier screen on a screen. Background technique [0002] There have been several approaches in the professional field of parallax barriers for a long time. A pioneer in this field was Frederic Ives, who in document GB190418672A introduced a system with a "grating" for 3D display. Also, in Sam H. Kaplan's "Theory of parallax barriers" - Journal of SMPTE, Vol. 59, No. 7, pp. 11-21, July 1952 - the basic understanding of using barrier screens for 3D displays is described . [0003] However, widespread dissemination of autostereoscopic systems has not been achieved for a long time. It wasn't until the 1980s that 3D systems saw a bit of a renaissance due to the computing power and new display technologies now available. In the 90s, the number of patent applications and publications related to glasses-free 3D visualization rose rapidly. The following inventors or contributors have notable achiev...
