VR AR Live Event Visualization System Perspective Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for capturing and presenting visual content of live events are not suited for virtual reality (VR) or augmented reality (AR) visualization, as they require significant processing time, leading to delays in streaming live content to VR/AR devices.
Innovation Solution
A content visualization system that collects visual content from multiple sources, determines relevant perspectives using device perspective data, and generates composited or non-composited visualization content efficiently, reducing processing time and the need for multiple visual content sources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If conventional methods are used to capture and present visual content from predetermined perspectives, then the system is simple to operate, but significant processing time is required causing delays in live streaming
Solution Approach 1:
The system pre-processes and stores visual content from multiple perspectives as the event unfolds, so that when a user requests a particular viewpoint, the content is already prepared and can be delivered immediately without requiring time-consuming real-time processing
Solution Approach 2:
The system creates multiple copies of the live event from different perspectives simultaneously using multiple cameras, allowing the user to switch between pre-captured perspectives without processing delays
2Reliability
If multiple visual content sources are used to provide immersive VR/AR experience, then the quality of visualization improves, but the computational load and system complexity increase
Solution Approach 1:
The system divides the visualization task into separate segments handled by different components: multiple cameras capture different perspectives, a server manages and processes the content, and the VR/AR device renders the final view. This segmentation allows each component to be optimized independently, reducing overall system complexity while maintaining high quality
Solution Approach 2:
The system uses a universal framework that can handle multiple visual content sources and perspectives through a common processing pipeline. The server can manage content from any number of cameras using the same algorithms for determining relevance and generating composited views, reducing complexity compared to having separate systems for each camera
3Productivity
If real-time processing is attempted to eliminate delays, then live streaming speed improves, but the computational requirements and processing complexity increase significantly
Solution Approach 1:
The system extracts only the relevant portions of visual content from multiple sources based on device perspective data, rather than processing all content equally. By identifying and extracting only the necessary perspectives and combining them selectively, the system reduces processing complexity while maintaining real-time performance
Data Source
AI summary
A content visualization system generates visual content for a visualization device based on visual content of an event. The content visualization system collects visual content and source perspective data from visual content sources. The visualization device requests visual content from the content visualization system by providing device perspective data to the content visualization system. The content visualization system generates visual content for the visualization device based on the visual content from the visual content sources, the source perspective data, and the device perspective data. The content visualization system can determine visual content that is relevant to the device perspective by identifying source perspectives that overlap with the device perspective. The content visualization system generates visual content for the visualization device based on the identified visual content. The content visualization system can generate composited or non-composited visual content, based on the similarity of the source perspectives to the device perspective.
