VR Image Reproduction Device for High-Definition Region Rendering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional virtual reality technology faces challenges in maintaining high image quality due to the stitching of 360° images, resulting in lower-than-expected HD quality for users, as the original video is distributed across a wide area, leading to a low-quality viewing experience.
Innovation Solution
The solution involves generating a wide area image and patch images of varying quality, which are stitched and played synchronously, along with divided images that can overlap or not, to enhance image quality and provide high-definition viewing experiences by focusing on specific areas of interest, while asynchronous content can be played independently to offer diverse expression methods.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the original image is stitched to create a 360° virtual reality image, then the coverage area is improved, but the image quality deteriorates
Solution Approach 1:
The patent divides the virtual reality image into multiple sub-images (first sub-image, second sub-image, third sub-image, fourth sub-image), each covering a specific field of view angle range. This segmentation allows each sub-image to be processed and rendered independently at high resolution, avoiding the quality loss that occurs when the entire 360° image is stitched as a single low-resolution image.
Solution Approach 2:
The patent applies different quality levels to different regions of the virtual reality image. Each sub-image is rendered with high definition quality in its specific field of view range, and the system dynamically selects and displays the appropriate sub-image based on the user's current viewing direction, ensuring that the region of interest always displays at maximum quality.
2Area of moving object
If the original video is distributed across a wide area, then the field of view is improved, but the viewing quality deteriorates
Solution Approach 1:
The patent implements a dynamic image selection mechanism that adjusts which sub-image is displayed based on the user's current viewing direction (field of view angle). The determination module continuously monitors the user's gaze direction and dynamically selects the appropriate high-definition sub-image, ensuring that the displayed content always matches the user's current viewing direction at maximum quality.
Solution Approach 2:
The patent transitions from a single 2D stitched image approach to a multi-dimensional solution by creating multiple independent sub-images, each optimized for a specific angular range. This allows the system to maintain high resolution across the entire 360° field of view by switching between different high-resolution sub-images rather than displaying a single low-resolution stitched image.
3Manufacturing precision
If multiple virtual reality images are stitched and played synchronously, then the image quality in specific regions is improved, but the system complexity increases
Solution Approach 1:
The patent segments the virtual reality content into multiple independent sub-images, each optimized for a specific field of view. This segmentation simplifies the rendering process by allowing each sub-image to be processed independently at high resolution, rather than attempting to render and stitch a single comprehensive image, thereby reducing overall system complexity while maintaining high quality.
Solution Approach 2:
The patent introduces a determination module as an intermediary that automatically selects which sub-image to display based on the user's current viewing direction. This intermediary component manages the complexity of handling multiple images by providing a simple decision-making mechanism, reducing the burden on the rendering system and simplifying the overall architecture.
