Multi-Camera Layout for Consistent Virtual Viewpoint Reproducibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing techniques for arranging multiple imaging apparatuses to generate virtual viewpoint images result in varying reproducibility of objects between different virtual viewpoints, especially in wide-range imaging target regions.
Innovation Solution
An arrangement determination apparatus that determines the placement of multiple imaging apparatuses to ensure that images of an entire region are captured by at least two imaging apparatuses, with different sets of apparatuses capturing the same region to maintain consistent reproducibility across the entire imaging target area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If imaging apparatuses are arranged along a circumference of a circle to direct toward the center, then the imaging target region can be covered, but the number of apparatuses capturing objects at different positions varies causing reproducibility differences
Solution Approach 1:
The patent applies local quality by determining the arrangement of imaging apparatuses based on the specific characteristics of different regions within the imaging target region. The arrangement determination unit calculates optimal positions and directions for each imaging apparatus considering the local requirements of different areas, ensuring that each region is captured by an appropriate number of apparatuses to maintain consistent reproducibility across the entire region.
2Area of stationary object
If multiple imaging apparatuses are used to capture the entire region, then coverage is improved, but the complexity of determining optimal arrangement increases
Solution Approach 1:
The arrangement determination unit automatically determines the optimal arrangement of imaging apparatuses through computational algorithms. The system self-services by calculating the required number of apparatuses, their positions, and directing angles based on the imaging target region characteristics, eliminating the need for manual arrangement planning and reducing operational complexity.
