Volumetric Representation of Real-World Events
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional virtual reality media content limits users to static viewpoints during real-world events, restricting their ability to experience events from desirable locations, such as the middle of a sporting event or concert stage, due to camera placement constraints.
Innovation Solution
A virtual reality media provider system uses synchronous video and depth capture devices to create a real-time volumetric representation of events, allowing users to dynamically select arbitrary viewpoints by generating a dynamic volumetric model of objects' surfaces, which includes both spatial and temporal data, enabling immersive experiences from any location.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional virtual reality media content uses static camera positions to capture real-world events, then the system complexity is reduced and ease of manufacture is improved, but the user experience freedom and adaptability are limited to fixed viewpoints
Solution Approach 1:
The capture system is divided into multiple independent camera units positioned at different locations, each capturing video from its own viewpoint. These segmented camera feeds are then processed separately and rendered based on user-selected viewpoints, allowing flexible adaptability without requiring a single complex movable camera system
Solution Approach 2:
The system transitions from static camera positions to dynamic viewpoint selection by capturing video from multiple fixed positions and then allowing users to dynamically switch between these viewpoints during playback. The render computer dynamically processes and presents different camera feeds based on user input, providing adaptability while maintaining simple fixed camera installations
2Ease of operation
If cameras are positioned at fixed locations to capture real-world events, then the ease of operation is improved and device complexity is reduced, but the ability to provide immersive experiences from desirable locations is limited
Solution Approach 1:
Multiple camera feeds from different fixed locations are merged into a unified virtual reality experience. The render computer combines video data from multiple sources and presents them as a cohesive immersive environment, allowing users to access viewpoints that would be impossible from a single camera position while keeping each individual camera simple to deploy
Solution Approach 2:
The multi-camera system provides universal coverage for multiple potential viewpoints simultaneously. Each camera serves multiple functions by capturing footage that can be presented from various virtual locations, and the system as a whole provides universal access to multiple perspectives that would otherwise require separate dedicated camera systems

AI summary
An exemplary virtual reality media provider system differentiates static objects depicted in two-dimensional video data from dynamic objects depicted in the two-dimensional video data. Based on the differentiating of the static objects from the dynamic objects, the virtual reality media provider system generates dynamic volumetric models of the surfaces of the static objects and the dynamic objects. The virtual reality media provider system updates the dynamic volumetric models of the surfaces of the static objects with a lower regularity or on an as-needed basis, and the virtual reality media provider system separately updates the dynamic volumetric models of the surfaces of the dynamic objects with a higher regularity. The higher regularity is higher than the lower regularity and keeps the dynamic volumetric models of the surfaces of the dynamic objects up-to-date with what is occurring in the two-dimensional video data. Corresponding methods and systems are also disclosed.
