Virtual Imaging Region Adjustment for Blind Spot Elimination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional surveillance systems using multiple cameras require manual prediction and creation of situational changes for imaging region adjustments, leading to inefficiencies and increased workload, especially when dealing with large numbers of cameras or camera failures.
Innovation Solution
An imaging region adjustment device that uses camera terminals with a communication unit to adjust virtual imaging regions, ensuring complete coverage of the target area without blind spots, allowing for dynamic reconfiguration and efficient handling of various-sized and shaped imaging regions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual prediction and creation of situational changes is used for imaging region adjustments, then imaging region coverage can be achieved, but workload increases and efficiency decreases
Solution Approach 1:
The camera terminal automatically adjusts its own imaging region based on received virtual imaging region information from other cameras, eliminating the need for manual prediction and creation of situational changes. The system performs self-adjustment through automated algorithms that process virtual region data and modify imaging parameters accordingly.
Solution Approach 2:
The system uses communication units to exchange virtual imaging region information between camera terminals, creating a feedback loop where each camera receives information about others' imaging regions and automatically adjusts its own imaging region to ensure complete coverage without blind spots.
2Reliability
If fixed camera positions are used for surveillance, then blind spots can be avoided in the imaging target region, but the system cannot handle camera failures or dynamic reconfiguration
Solution Approach 1:
The system dynamically adjusts imaging regions based on real-time virtual imaging region information received from other camera terminals. Camera terminals can change their imaging regions on-the-fly to adapt to camera failures or reconfiguration needs, maintaining complete coverage without requiring fixed positions.
Solution Approach 2:
The adjusting unit serves multiple functions: it receives virtual imaging region information, processes this information to determine optimal imaging regions, and executes adjustments to maintain complete surveillance coverage. This multi-functional approach allows the system to handle various scenarios including camera failures and dynamic reconfiguration.
3Area of stationary object
If multiple cameras are used to cover large areas, then complete surveillance coverage is achieved, but the complexity of managing and coordinating the cameras increases
Solution Approach 1:
The surveillance area is divided into multiple virtual imaging regions, with each camera terminal responsible for a specific virtual region. This segmentation allows independent adjustment and management of each camera's imaging region based on the virtual region information received from other terminals, simplifying coordination while maintaining complete coverage.

AI summary
An imaging region adjustment device includes plural camera terminals, capable of imaging an entire imaging target without blinds spots. Each of the camera terminals includes a camera which images a virtual imaging region obtained while changing the position of an imaging region within a specific region in a specific period of time and an adjusting unit B which adjusts the position of the virtual imaging region by controlling the camera. The adjusting unit B adjusts the position and aspect ratio of the virtual imaging region of one's own camera terminal so that a combined region of the virtual imaging regions of the camera terminals completely covers a specific imaging target region, based on the virtual imaging region of one's own camera terminal and virtual imaging regions of the other camera terminals, and when the virtual imaging regions A of N other camera terminals are contained in the virtual imaging region of one's own camera terminal, divides the virtual imaging region of one's own camera terminal into N+1 regions.
