Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 3D display technologies face challenges in efficiently processing and transmitting image data to multiple viewpoints, leading to increased data processing and network transmission pressures, especially when dealing with multiple viewers in different sub-regions.
Innovation Solution
A method for processing 3D image data that determines the target view based on the number of sub-regions and viewpoints, adjusting the resolution and transmission accordingly, and utilizing a computer device with a processor and memory to execute this method, which includes receiving indication information, determining the target view, and transmitting image data to 3D display terminals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If image data for all viewpoints is transmitted to ensure viewing quality for multiple viewers, then viewing experience is improved, but network transmission pressure and data processing load increase significantly
Solution Approach 1:
The patent applies local quality by transmitting different quantities of image data to different display terminals based on their specific viewing conditions. Each terminal receives image data tailored to its local context (number of viewers, viewer positions, sub-region location), rather than uniformly transmitting all viewpoint data to all terminals. This resolves the contradiction by optimizing data transmission volume for each local situation while maintaining appropriate viewing quality.
Solution Approach 2:
The patent implements dynamics by making the image data transmission adaptive and variable based on real-time conditions. The system dynamically adjusts which viewpoint image data is transmitted to each display terminal according to the number of viewers, their positions, and the terminal's sub-region. This dynamic adaptation allows the system to maintain viewing quality while minimizing data transmission volume under varying conditions.
2Manufacturing precision
If high resolution image data is transmitted for all viewpoints, then image quality is improved, but data processing pressure and network bandwidth consumption increase
Solution Approach 1:
The patent applies local quality by transmitting image data with appropriate resolution and completeness tailored to each display terminal's specific viewing conditions. Rather than uniformly transmitting high-resolution data for all viewpoints to all terminals, each terminal receives image data optimized for its local context (number of viewers, their positions, sub-region location). This resolves the contradiction by maintaining image quality where needed while reducing processing power consumption where fewer viewers are present.
3Productivity
If viewpoint information is precisely determined for each viewer to optimize data transmission, then network efficiency is improved, but system complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the viewing region into multiple sub-regions and determining viewpoint information separately for each sub-region. The system segments viewers based on their positions and assigns appropriate viewpoint image data from the set of N viewpoint image data according to which sub-region they occupy. This segmentation approach improves network efficiency by reducing unnecessary data transmission while managing system complexity through structured regional division rather than individual viewer tracking.
