Virtual Viewpoint Image Ad Placement via Dynamic Parameter Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing techniques for generating virtual viewpoint images cannot add advertisement information when the viewpoint conditions differ from the pre-set specific conditions, limiting flexibility in displaying ads in free-viewpoint videos.
Innovation Solution
An information processing apparatus that sets parameters for displaying additional information in virtual viewpoint images, including virtual advertisement data, time codes, and viewpoint information, allowing for dynamic addition of ads at desired positions and times within the image generation process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If advertisement information is added to virtual viewpoint images using pre-set viewpoint conditions, then advertisement display is enabled, but the system loses flexibility when viewpoint conditions differ from the pre-set conditions
Solution Approach 1:
The patent applies dynamics by transitioning from static pre-set viewpoint conditions to dynamic viewpoint condition matching. The system now dynamically determines correspondence between virtual viewpoint images and advertisement display conditions based on actual viewpoint parameters, allowing flexible ad placement regardless of whether the viewpoint matches pre-set conditions exactly.
Solution Approach 2:
The patent changes the parameter approach by moving from fixed viewpoint condition parameters to variable parameters that can adapt to different virtual viewpoint configurations. The system uses viewpoint condition information as a parameter that can be dynamically adjusted and matched against actual viewpoint parameters to determine appropriate advertisement display conditions.
2Reliability
If the system requires exact viewpoint condition matching for ad display, then advertisement placement precision is improved, but the system cannot handle varying viewpoint conditions
Solution Approach 1:
The patent implements feedback by establishing a loop where actual viewpoint parameters are continuously compared with advertisement display conditions, and the system adjusts its behavior based on this comparison. The viewpoint condition information serves as feedback that guides the determination of appropriate advertisement display conditions, ensuring reliable ad placement while adapting to varying viewpoints.
Solution Approach 2:
The patent applies preliminary action by pre-establishing viewpoint condition information and advertisement display condition correlations before actual ad display is needed. This preliminary setup allows the system to reliably determine appropriate advertisements for given viewpoints without requiring complex real-time calculations, while still maintaining adaptability to different viewpoint conditions.
