Layer Projection for 6DoF Stereoscopic Image Quality
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for providing 6DoF omni-directional stereoscopic images based on actual-object images are in the early stages of research, lacking efficient solutions for preventing holes between layers, reducing encoding and decoding overhead, and maintaining image quality, especially in representing motion and binocular parallax across a 360-degree space.
Innovation Solution
A method and apparatus utilizing layer projection to generate and display omni-directional stereoscopic images by constructing spatial-information-point subsets for each layer, including duplicate points, and performing layer projection based on user translation and rotation, which enhances depth perception and reduces image quality disharmony between layers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If layer projection is applied to omni-directional stereoscopic images, then depth perception is enhanced and image quality consistency is improved, but encoding and decoding overhead increases
Solution Approach 1:
The spatial information is segmented into multiple layers based on depth distances, with each layer containing spatial information points within a specific depth range. This segmentation enables independent processing of each layer, improving image quality consistency while managing encoding complexity through structured organization
Solution Approach 2:
Duplicate spatial information points are pre-included in adjacent layers before encoding. This preliminary action prevents holes between layers during viewpoint translation and eliminates the need for complex post-processing, reducing decoding overhead while maintaining image quality
2Reliability
If spatial-information-point subsets are constructed with duplicate points for each layer, then holes between layers are prevented, but data redundancy increases
Solution Approach 1:
Duplicate spatial information points are strategically placed only at boundaries between adjacent layers where holes would occur during viewpoint translation. This local application of redundancy prevents holes without unnecessarily increasing data quantity across the entire dataset
Solution Approach 2:
Instead of creating complete redundancy across all layers, the patent applies partial redundancy only where necessary at layer boundaries. This excessive action is minimized to the exact extent needed to prevent holes, avoiding unnecessary data duplication
