Single-Image 3D Display Using Parallax Without Viewer Fatigue
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional 3D imagery systems cause discomfort and fatigue due to the decoupling of vergence and accommodation processes, leading to perceptual depth distortions and visual discomfort, as they force viewers to adjust vergence and accommodation separately, disrupting the natural correlation between these processes.
Innovation Solution
A 2D image capture system that generates a 3D infilled mesh from a depth map, applies parallax, and renders a stereo pair of images, allowing for multi-dimensional image display without specialized glasses or headsets, using a display with integrated lens arrays to refract light and align images based on the interpupillary distance for clear and sharp viewing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional stereoscopic displays are used to provide depth information through binocular disparity, then depth perception is improved, but the vergence-accommodation conflict causes visual discomfort and eye fatigue
Solution Approach 1:
The patent uses a single 2D image capture device to capture images, then creates a simulated second image by rotating the captured image by 1-180 degrees to generate stereoscopic pairs. This copying approach eliminates the need for multiple physical cameras while still producing the binocular disparity needed for depth perception, thereby avoiding the vergence-accommodation conflict that plagues conventional stereoscopic displays.
Solution Approach 2:
The patent transforms a 2D captured image into a 3D stereoscopic experience by rotating the image plane and creating depth through parallax effects. The processor generates a simulated second image from the first captured image through rotational transformation, adding the depth dimension without requiring multiple physical capture devices or specialized display equipment.
2Measurement precision
If multiple digital image capture devices are positioned approximately an interpupillary distance apart to capture 2D source images, then 3D depth perception is achieved, but device complexity increases
Solution Approach 1:
Instead of using multiple physical capture devices positioned at interpupillary distance, the patent captures a single 2D image and creates a simulated second image by rotating the captured image. This copying method generates the necessary binocular disparity for 3D depth perception while using only one physical capture device, significantly reducing system complexity.
Solution Approach 2:
The patent replaces the mechanical arrangement of multiple physically separated capture devices with a computational approach. The processor rotates the captured image by 1-180 degrees to generate a simulated second image, substituting physical separation with mathematical transformation to achieve the same stereoscopic effect.
3Manufacturing precision
If the key subject point is aligned and parallax is maintained within comfortable limits, then image quality and viewer comfort are improved, but processing complexity increases
Solution Approach 1:
The patent performs preliminary alignment of the key subject point and establishes comfortable parallax limits during the image processing stage. By pre-calculating the rotation angle (1-180 degrees) and adjusting the simulated second image to maintain key subject alignment, the system ensures optimal image quality and viewer comfort before display, avoiding the need for complex real-time adjustments.
