Real-Time VR Broadcasting Without Image Stitching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current virtual reality (VR) stitching technologies require significant time and resources to accurately connect images from multiple cameras, leading to time delays in broadcasting live 360 VR content, making real-time streaming impossible.
Innovation Solution
A real-time broadcasting device and method that selects and transmits only the VR image corresponding to the user's gaze direction from multiple cameras positioned to shoot in different directions, without stitching, using an image selector, transmitter, and gaze direction receiver to ensure seamless and immediate content delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If stitching technology is used to connect images from multiple cameras, then the quality and accuracy of 360 VR images are improved, but the time required for processing increases significantly, making real-time broadcasting impossible
Solution Approach 1:
The patent extracts and transmits only the specific image portion corresponding to the user's gaze direction from multiple camera feeds, rather than processing and stitching all images. This selective extraction eliminates the time-consuming stitching process while maintaining image quality for the relevant viewing area.
Solution Approach 2:
The patent divides the 360 VR scene into multiple segments captured by different cameras, each covering a specific field of view. Instead of combining all segments through stitching, the system independently selects and transmits the appropriate segment based on user gaze direction, avoiding the need for post-processing integration.
2Adaptability or versatility
If multiple cameras are used to capture 360 VR content, then the coverage and immersion quality are improved, but the complexity of the broadcasting system increases due to the need for stitching
Solution Approach 1:
The system extracts only the necessary image portion from the multiple camera feeds based on user gaze direction, eliminating the need for complex stitching operations. This approach maintains comprehensive coverage capability while significantly reducing system complexity by removing the stitching processing chain.
3Manufacturing precision
If image stitching is performed to ensure accurate color and position matching, then the visual quality is improved, but the processing time and computational resources are significantly consumed
Solution Approach 1:
The patent extracts and transmits only the relevant image portion corresponding to user gaze direction without performing any stitching operations. This eliminates computational image processing entirely, maintaining visual quality for the selected region while achieving real-time processing capability.
Solution Approach 2:
Instead of processing the complete 360-degree scene with all its stitching requirements, the system performs partial processing by selecting only the necessary portion of the image that corresponds to the user's current view, thereby achieving real-time performance with reduced computational load.

AI summary
A real-time broadcasting device includes a plurality of image capturing units arranged to capture images at the same time in different directions from the same point; an image selection unit for comparing the angle of view covered by each of the plurality of image capturing units and the gaze direction of a user terminal, and selecting an image of the image capturing unit, among the plurality of image capturing units, capturing images corresponding to the gaze direction of the user terminal; an image transmission unit for transmitting virtual reality images captured by the image capturing unit selected by the image selection unit to the user terminal in real time; and a gaze direction reception unit for receiving feedback about which direction the gaze direction of the user terminal viewing the virtual reality images is, and transmitting same to the image selection unit.
