Movable Camera Array Video Layout via Position Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing monitoring camera systems with multiple image capturing units struggle to display a single continuous area effectively when multiple units are combined, as the videos are often divided and not laid out correctly on the display screen.
Innovation Solution
An image capturing apparatus comprising multiple movable image capturing units, a detection unit to determine their positions, and a generation unit that sets the positional relationship between video data from these units to match their actual positions, ensuring proper layout and display of videos shot by multiple cameras.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If multiple image capturing units are combined to shoot one continuous area, then the monitoring coverage is improved, but the videos are divided and displayed incorrectly on the screen
Solution Approach 1:
The patent applies dimensional transformation by mapping the spatial positional relationships from the physical three-dimensional space to the two-dimensional display screen. The generation unit calculates positional relationships between multiple image capturing units and transforms them into corresponding layout positions on the display screen, enabling videos from multiple cameras to be arranged in a spatially accurate manner that reflects their actual physical arrangement.
2Device complexity
If a plurality of videos are displayed in a predetermined layout, then the display structure is simplified, but the positional relationship between videos does not match the actual camera positions
Solution Approach 1:
The patent implements feedback by using detection units to continuously obtain positional information from multiple image capturing units, then feeding this information back to the generation unit which adjusts the video layout accordingly. This closed-loop system ensures that the display layout dynamically reflects the actual positional relationships between cameras, maintaining accuracy without increasing structural complexity.
3Productivity
If the distribution order of videos is changed to handle overlapping areas, then the video distribution is optimized, but the problem of divided display of continuous area remains unsolved
Solution Approach 1:
The patent applies local quality by treating each video's positional relationship individually based on its specific camera location. Rather than using a uniform distribution approach, the generation unit calculates and applies unique positional relationships for each camera pair, ensuring that videos from cameras capturing continuous areas are displayed with their correct spatial relationships preserved.

AI summary
An image capturing apparatus comprises a plurality of movable image capturing units, a detection unit configured to detect positions of the respective image capturing units, and a generation unit configured to generate video data in which videos obtained by the image capturing units are laid out based on a detection result of the detection unit. The generation unit sets a positional relationship in the video data between at least two videos obtained by at least two image capturing units out of the image capturing units to coincide with a positional relationship between the at least two image capturing units.
