Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for generating virtual reality environments from sporting events are limited to static views, offering minimal user interaction and control, restricting the immersive experience.
Innovation Solution
A system and method for user-controlled virtual cameras that synchronize multiple panoramic camera heads through a time code generator, allowing users to interactively choose their viewing angle and control playback speed and direction across all video streams in a synchronous manner, enabling immersive volumetric video experiences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple panoramic camera heads are synchronized through a time code generator, then the system enables interactive user control and dynamic viewing angles, but the device complexity increases
Solution Approach 1:
The system divides the volumetric video capture into multiple independent panoramic camera heads, each capturing data from a specific direction. This segmentation allows users to selectively view from different camera perspectives while maintaining manageable system complexity through modular architecture.
Solution Approach 2:
The time code generator serves as a universal synchronization mechanism that coordinates all panoramic camera heads simultaneously. This single device enables multi-functional operation across the entire camera array, allowing interactive user control without proportionally increasing overall system complexity.
2Adaptability or versatility
If users can interactively select vantage points and control playback, then the immersive experience is enhanced, but the ease of operation becomes more complex
Solution Approach 1:
The system creates virtual camera views that replicate and combine data from multiple physical panoramic camera heads. Users interact with these synthesized virtual views rather than directly controlling each physical camera, simplifying the user interface while maintaining comprehensive control capability.
3Measurement precision
If pixel-to-pixel correspondence is established between physical and virtual camera images, then measurement precision improves, but the processing time increases
Solution Approach 1:
The system performs preliminary synchronization by aligning all panoramic camera heads to a common time code before generating virtual camera views. This pre-alignment establishes pixel-to-pixel correspondence in advance, reducing the computational burden and processing time during actual view generation.

AI summary
Apparatus and method for determining a quality score for virtual video cameras. For example, one embodiment comprises: a region of interest (ROI) detector to detect regions of interest within a first image generated from a first physical camera (PCAM) positioned at first coordinates; virtual camera circuitry and/or logic to generate a second image positioned at the first coordinates; image comparison circuitry and/or logic to establish pixel-to-pixel correspondence between the first image and the second image; an image quality evaluator to determine a quality value for the second image by evaluating the second image in view of the first image.
