Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional 3D image displays cause eye fatigue and compromise image quality due to the decoupling of vergence and accommodation processes, leading to perceptual depth distortions and discomfort.
Innovation Solution
A smart device with a 2D digital image capture system, image processing, and display capabilities that captures a single 2D image, generates a depth map, creates a 3D infilled mesh, and applies parallax to render a sequence of multidimensional digital images, allowing for the simulation of 3D images without specialized viewing devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional 3D image displays are used to provide stereoscopic depth perception, then depth perception capability is improved, but visual comfort and image quality deteriorate due to vergence-accommodation conflict
Solution Approach 1:
The patent applies dynamics by making the focal plane adjustable and dynamic rather than fixed. The system dynamically adjusts the focal plane to different depths corresponding to different disparity planes, allowing the focal distance to change in response to the displayed depth information. This dynamic adjustment enables the focal plane to track the disparity plane, resolving the vergence-accommodation conflict while maintaining depth perception capability.
Solution Approach 2:
The patent changes the focal plane parameter to match the disparity plane parameter. By adjusting the focal distance to correspond to the depth information encoded in the disparity, the system aligns the accommodation distance with the vergence distance. This parameter coordination eliminates the conflict between vergence and accommodation, improving visual comfort while preserving stereoscopic depth perception.
2Measurement precision
If multiple 3D cameras are used to capture images from different positions to achieve depth perception, then depth information accuracy is improved, but device complexity increases
Solution Approach 1:
The patent uses a single camera to capture a 2D image, then creates multiple virtual camera views through computational methods. By generating synthetic images from different virtual positions based on the single captured image and depth map, the system achieves multi-view depth perception without requiring multiple physical cameras. This copying approach maintains depth information accuracy while significantly reducing device complexity.
Solution Approach 2:
The patent replaces the mechanical system of multiple physical cameras with a computational system. Instead of using multiple cameras positioned at different locations to capture images simultaneously, the system uses a single camera combined with algorithms to generate virtual multi-view images. This substitution of mechanical complexity with computational processing achieves the same depth perception function with simpler hardware.
3Ease of operation
If 3D images are displayed on standard 2D devices without specialized viewing equipment, then ease of operation is improved, but image quality and depth perception deteriorate
Solution Approach 1:
The patent encodes three-dimensional depth information within the two-dimensional image plane by utilizing disparity planes at different depths. By embedding depth data in the spatial arrangement and pixel variations within the 2D image, the system creates a multidimensional representation that can be displayed on standard 2D devices. This allows 3D depth perception to be achieved without specialized viewing equipment while maintaining image quality.
Solution Approach 2:
The patent creates a universal image format that can be displayed on both standard 2D devices and specialized 3D displays. The generated images contain encoded depth information that works across different display types without requiring specialized viewing equipment. This multi-functional approach maintains ease of operation on common devices while preserving depth perception capability through the encoded disparity information.
