Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional 3D stereoscopic technologies require specialized equipment for capturing images, limiting the ability to create 3D images or videos from conventional 2D sources.
Innovation Solution
A system and method for generating stereoscopic 3D images or videos by extrapolating and rendering complementary 2D images, allowing viewers to perceive depth by shifting and modifying the appearance of objects within the scene based on calculated shifts and viewing angles, using 2D or 3D skeletal models to estimate depth and create complementary images.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional 3D stereoscopic technologies use twin cameras with fixed distance between lenses, then stereoscopic images can be captured, but specialized equipment is required which limits accessibility and application scope
Solution Approach 1:
The patent creates a virtual copy of the second image by shifting and modifying it to simulate the perspective that would be captured by a second camera positioned at a different location. This virtual copy replaces the need for actual twin cameras, allowing 3D stereoscopic image generation from conventional 2D sources alone
Solution Approach 2:
The patent transitions from 2D image data to 3D stereoscopic output by introducing a virtual depth dimension. Through computational shifting and modification of image pixels, the system creates the perception of three-dimensional space from flat two-dimensional sources, effectively adding a dimensional aspect without physical 3D capture equipment
2Reliability
If twin cameras are used to capture stereoscopic images, then depth perception is achieved, but the system complexity and cost increase
Solution Approach 1:
The patent replaces the mechanical optical system of twin cameras with a computational image processing system. Instead of using physical cameras positioned at different locations to capture stereoscopic pairs, the system uses algorithms to shift and modify pixels from a single 2D image, substituting mechanical complexity with computational processing while maintaining depth perception capability
3Manufacturing precision
If specialized stereoscopic capture equipment is used, then 3D image quality is improved, but viewer compatibility and broader application are limited
Solution Approach 1:
The patent creates a universal 3D image generation system that works with conventional 2D cameras and produces output compatible with various stereoscopic display technologies. The computational approach allows the same system to generate 3D images from any 2D source that can be displayed on standard screens, making the solution broadly applicable across different devices and platforms without requiring specialized capture equipment

AI summary
The present invention includes methods, systems, devices and associated processing logic for generating stereoscopic 3-Dimensional images and/or video from 2-Dimensional images or video. There may be provided a stereoscopic 3D generating system to extrapolate and render 2D complementary images and or video from a first 2D image and/or video. The complementary images and/or video, when combined with the first image or video, or a second complementary image or video, form a stereoscopic image of the scene captured in the first image or video. The stereoscopic 3D generation system may generate a complementary image or images, such that when a viewer views the first image or a second complementary image (shifted in the other direction from the first complementary image) with one eye and the complementary image with the other eye, an illusion of depth in the image is created (e.g. a stereoscopic 3D image).
