Daisy Chain Image Capture Rerouting for Data Reliability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In daisy chain connected image capturing systems, abnormalities in one unit can lead to failed data transmission from subsequent units and traffic imbalances, resulting in delayed or incomplete data arrival at the destination.
Innovation Solution
An information processing apparatus that acquires state information from each image capturing unit and adjusts the output destination of image data based on this information to ensure continuous and balanced data transmission, using a control apparatus to reroute data around faulty units and manage traffic imbalances.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If image capturing units are connected in a daisy chain connection, then the system structure is simple and easy to implement, but data transmission reliability deteriorates when an abnormality occurs in one unit
Solution Approach 1:
The patent segments the daisy chain connection into multiple independent transmission paths by introducing a star topology with a central management device. Each image capturing unit connects to the central device independently, creating separate transmission channels that do not interfere with each other, thus maintaining simplicity while improving reliability.
Solution Approach 2:
The patent introduces a central management device as an intermediary between image capturing units and the server. This intermediary coordinates data transmission, manages communication routes, and handles abnormalities, thereby protecting the overall system from failures in individual units while maintaining the simplicity of the connection structure.
2Ease of operation
If image capturing units are connected in a daisy chain connection, then the system is easy to install and configure, but traffic imbalance occurs on transmission paths
Solution Approach 1:
The patent divides the single daisy chain transmission path into multiple segmented paths by connecting each image capturing unit directly to a central management device. This segmentation distributes traffic across multiple independent channels, preventing traffic concentration and imbalance while maintaining ease of installation through modular connections.
Solution Approach 2:
The patent implements dynamic traffic management by enabling the central management device to flexibly allocate and adjust transmission routes based on real-time system state information. This dynamic adjustment optimizes data transmission efficiency by balancing traffic loads across available paths while preserving the simplicity of the physical connection structure.
3Device complexity
If image capturing units are connected in a daisy chain connection, then the system requires fewer connection components, but data arrival time varies due to traffic imbalances
Solution Approach 1:
The patent segments the transmission architecture into parallel independent paths by introducing a central management device that each unit connects to separately. This reduces the number of sequential connection components needed in a daisy chain while simultaneously eliminating data arrival time variations through balanced, concurrent transmission channels.
Solution Approach 2:
The patent changes the topological parameter of the connection structure from a linear daisy chain to a star topology with a central hub. This parameter change fundamentally alters data flow characteristics, enabling simultaneous transmissions with synchronized arrival times at the server, thereby reducing time variation while maintaining low component complexity.

AI summary
An exemplary embodiment of the present disclosure is directed to more appropriately transmitting image data output from image capturing units connected in a daisy chain connection. State information indicating a state of each of a plurality of image capturing units that are connected in a daisy chain connection and acquire image data to be transmitted to an image generation apparatus, which generates a virtual viewpoint image, in accordance with the daisy chain connection is acquired. An output destination of the image data for at least one image capturing unit included in the plurality of image capturing units is changed based on the acquired state information.
