Virtual-Viewpoint Content Processing Using Pre-Generated Model Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for generating virtual-viewpoint content face user-unfriendliness due to long processing times and uncertainty about the availability of necessary material data, leading to delayed recognition of content generation failures.
Innovation Solution
A system that pre-generates and stores material data for three-dimensional models, including texture and color information, and provides time range management information to ensure efficient generation of virtual-viewpoint content by querying the availability of necessary data before processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If three-dimensional models are generated on-demand from multi-viewpoint images, then the system can produce virtual-viewpoint content with high flexibility, but the processing time becomes excessively long and user-friendliness deteriorates
Solution Approach 1:
The patent applies preliminary action by pre-generating three-dimensional models from multi-viewpoint images and storing them in advance before they are needed for virtual-viewpoint content generation. This allows the system to quickly retrieve and use pre-processed models when users request content, eliminating the need for time-consuming on-demand generation while maintaining flexibility in creating virtual-viewpoint content from various angles and perspectives.
2Reliability
If the system checks availability of material data before content generation, then generation failures can be prevented, but the complexity of the system increases
Solution Approach 1:
The patent implements feedback by establishing a query mechanism that checks the availability of pre-generated three-dimensional models and material data before initiating virtual-viewpoint content generation. The system receives queries about data availability, checks storage databases, and returns information about whether required models exist. This feedback loop ensures reliable content generation by preventing attempts to create content without necessary materials, while the automated nature of the check minimizes the perceived complexity for users.

AI summary
An information processing apparatus specifies (5) that material data for generating a virtual-viewpoint content at what time is stored in a storage device that stores a plurality of material data for generating a virtual-viewpoint content; and outputs (10), based on a result of the specification, information for causing an image to be displayed, the image indicating a time at which a virtual-viewpoint content can be generated.
