Autostereoscopic Display Scaling for Realistic 3D Content
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Autostereoscopic displays struggle to realistically present three-dimensional recorded items to viewers, particularly when the display acts as a virtual window, as the dimensions of displayed content do not match those of real-world objects and do not change with viewer movement.
Innovation Solution
A method for driving an autostereoscopic display that involves scaling three-dimensional content based on the viewer's viewing distance and the recording distance of the object to the stereo camera, ensuring that the dimensions of the displayed image match those of the real object.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If three-dimensional content is displayed on an autostereoscopic display without scaling, then the display can present 3D images to viewers, but the dimensions of displayed content do not match those of real-world objects
Solution Approach 1:
The patent applies preliminary action by pre-calculating and applying the appropriate scaling factor to the three-dimensional content before display. The system determines the recording distance from the stereo camera and the viewing distance from the viewer, calculates the required scaling factor in advance, and applies this scaling to ensure dimensional accuracy is achieved without requiring complex real-time adjustments during viewing.
2Adaptability or versatility
If the displayed content size remains fixed, then the display system is simple to operate, but the size of displayed items does not change when the viewer moves towards or away from the display
Solution Approach 1:
The patent implements dynamics by making the displayed content size adaptive to viewer movement. The system continuously monitors or estimates the viewer's viewing distance and dynamically adjusts the scaling of the three-dimensional content accordingly. This allows the displayed items to change size in proportion to viewer movement, creating a more realistic and immersive experience while maintaining a relatively simple display architecture.

AI summary
The invention relates to a method for driving a screen of an autostereoscopic display device to present a three-dimensional image to a viewer, the method comprising scaling of the three-dimensional image. taking into account 1) the 5 viewing distance of the viewer's eyes to the screen: and 2) the recording distance of the object. In this way. a the three-dimensional image of one or more specific objects in a scene can be scaled in such way that the scene and the object(s) therein become a realistic part of the real environment of the viewer. It is also possible to display a background image on the screen wherein the background 10 image is also scaled to realistic dimensions.
