3D Animation Stereo Depth Correction via Inter-Axial Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional 3D animation methods are complex and require significant effort, lacking efficient tools to reduce complexity while maintaining high quality, particularly in achieving consistent stereo depth and correcting for parallax issues.
Innovation Solution
The system employs a computer apparatus with storage and display means to create and manage 3D animations by calculating inter-axial distances, multi-rigging, and post-production techniques to isolate and treat foreground objects, correct parallax, and generate stereoscopic effects, including hole-filling and real-time compositing of stereo camera views.

Engineering Contradiction Analysis
1Manufacturing precision
If conventional 3D animation methods are used to achieve stereoscopic effects, then 3D animation quality can be maintained, but the process complexity and effort required increase significantly
Solution Approach 1:
The patent segments the 3D animation process by separating foreground and background elements into different rendering pipelines. Foreground objects are rendered with one inter-axial distance while background elements use a different inter-axial distance, allowing independent optimization of each segment's stereo effect without increasing overall process complexity
Solution Approach 2:
The system performs preliminary calculation of inter-axial distances based on object depth and parallax requirements before rendering. By pre-determining the appropriate inter-axial distance for different scene elements, the system eliminates the need for complex manual adjustment during the animation process while maintaining high stereo quality
2Stability of the object's composition
If inter-axial separation is automatically calculated to match constant background parallax, then consistent stereo depth is achieved, but handling of foreground objects with different parallax becomes complex
Solution Approach 1:
The patent applies different inter-axial distance settings to different spatial regions of the scene. Background elements use a constant parallax inter-axial distance for consistency, while foreground objects receive locally optimized inter-axial distances based on their specific depth and parallax requirements, allowing each region to have the quality appropriate to its needs
Solution Approach 2:
The system dynamically adjusts inter-axial distances based on object depth and parallax characteristics rather than using a fixed value throughout the scene. This dynamic adjustment allows the system to maintain consistent stereo depth for background elements while adapting to the varying parallax requirements of foreground objects at different depths
3Measurement precision
If multiple camera rigs are used to isolate foreground objects, then parallax control is improved, but the number of cameras and system complexity increase
Solution Approach 1:
The patent implements a universal rendering system that can handle both foreground and background elements through a single integrated pipeline. The system uses depth-based classification to automatically assign appropriate inter-axial distances, eliminating the need for separate camera rigs while maintaining precise parallax control through software-based differentiation
