Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple cameras are used to generate virtual viewpoint images, then image quality can be improved, but it becomes difficult to determine optimal imaging positions and directions for each camera
Solution Approach 1:
The patent introduces an information processing apparatus as an intermediary between the multiple cameras and the virtual viewpoint image generation system. This apparatus calculates and provides guidance information about optimal imaging positions and directions, thereby simplifying the complex task of coordinating multiple cameras while maintaining high image quality for virtual viewpoint generation.
2Adaptability or versatility
If camera positions are freely adjustable, then flexibility in imaging setup is improved, but it becomes harder to ensure high-quality virtual viewpoint image generation
Solution Approach 1:
The patent implements a feedback mechanism where the information processing apparatus evaluates the current camera positions and directions, then provides guidance information back to the imaging system. This feedback loop ensures that even with flexible camera positioning, the system maintains optimal configurations for high-quality virtual viewpoint image generation by continuously guiding adjustments based on calculated criteria.
