Three-Dimensional Model Viewpoint Generation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional viewing experiences of events are limited by camera positions, restricting spectators' perspectives and failing to provide immersive and dynamic viewpoints.
Innovation Solution
A system that determines location and movement data of objects and participants within an event area, generates a three-dimensional model, and allows spectators to select viewpoints, incorporating light-field data and virtual grids to enhance the viewing experience, including the ability to remove obstructions and add special effects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple cameras are used to provide multiple perspectives, then the viewing perspective diversity is improved, but the device complexity increases
Solution Approach 1:
The patent creates a three-dimensional model (copy) of the event area based on data from multiple cameras, allowing virtual viewpoint generation without requiring physical cameras at every possible viewing position. This copy enables spectators to experience multiple perspectives through virtual reality without proportionally increasing the physical camera infrastructure.
Solution Approach 2:
The patent transitions from two-dimensional camera views to three-dimensional modeling, enabling viewpoints from any position and angle within the event area. By creating a 3D model with depth, width, and height information, the system provides immersive viewing experiences that go beyond the limitations of traditional 2D camera feeds.
2Manufacturing precision
If a three-dimensional model is generated with high detail, then the viewing experience quality is improved, but the processing time increases
Solution Approach 1:
The patent implements selective rendering where only the portions of the three-dimensional model relevant to the current viewpoint are processed in high detail. Less important areas are rendered with lower detail, reducing overall processing requirements while maintaining quality where it matters most for the spectator's viewing experience.
Solution Approach 2:
The system dynamically adjusts the level of model detail based on the selected viewpoint and spectator position. As the viewpoint changes, the processing focus shifts to relevant areas, allowing high-quality rendering of only necessary portions rather than processing the entire model at maximum detail continuously.
3Reliability
If light-field data is captured to enhance the three-dimensional model, then the viewing experience immersion is improved, but the data processing complexity increases
Solution Approach 1:
The patent uses light-field data captured by existing camera systems to serve multiple functions: enhancing the three-dimensional model accuracy, improving rendering quality, and enabling more realistic lighting effects. This multi-functional use of light-field data maximizes the value extracted from the additional data without requiring separate dedicated systems for each function.
4Speed
If virtual images and sounds are generated in real-time, then the viewing experience responsiveness is improved, but the processing power required increases
Solution Approach 1:
The system pre-processes and stores three-dimensional model data, camera positions, and event information before generating final virtual images and sounds. By preparing data structures and models in advance, the system reduces real-time processing requirements while maintaining responsive viewing experience generation when spectators interact with the system.
Data Source
AI summary
Systems and processes generate a viewing experience by determining location data and movement data of (a) at least one object and (b) at least one participant within an event area. A three-dimensional model of the event area, the participant and the object is determined based upon the location data and the movement data. A viewpoint of a spectator defines an origin, relative to the three-dimensional model, and a direction of the viewing experience. The viewing experience is generated for the viewpoint at least in part from the three-dimensional model to include one or more of augmented reality, mixed reality, extended reality, and virtual reality.
