Consolidating Camera Image Data into Single Group Files
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current network camera systems manage images from multiple cameras as separate files, leading to increased resource consumption and load burdens during monitoring, especially when handling a large number of images.
Innovation Solution
A data management device and method that groups selected cameras and manages their captured images as a single file, reducing resource usage by storing and processing image data in a single group file, allowing for efficient data extraction and playback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If images from multiple network cameras are managed as separate files, then each camera's image data can be independently stored and accessed, but resource consumption increases and load burden increases during monitoring
Solution Approach 1:
The patent merges image data from multiple network cameras into a single file by grouping cameras and consolidating their image frames sequentially within one file structure. This combining approach reduces the number of file access operations and data extraction processes, thereby lowering resource consumption while maintaining the ability to access and display images from individual cameras through logical positioning within the unified file.
2Adaptability or versatility
If images from multiple network cameras are managed as separate files, then data from each camera can be independently extracted, but a lot of resources are consumed for data reading when there are many images
Solution Approach 1:
The patent combines image data from multiple cameras into a single file with a unified structure that includes global headers and sequentially arranged image frames from different cameras. This merging improves productivity by reducing the number of file opening/closing operations and data extraction processes, while adaptability is maintained through metadata that identifies camera sources and frame positions, enabling selective extraction when needed.
Solution Approach 2:
The unified file structure serves multiple functions: it acts as a single consolidated data container for efficient processing, while also maintaining internal organization that allows for camera-specific data extraction. The file structure includes metadata that enables the system to identify and access images from specific cameras within the unified file, providing multi-functional capability that improves both productivity and adaptability.
3Device complexity
If images from multiple cameras are stored as separate files, then each file can be managed independently, but the monitoring device experiences increased load burden
Solution Approach 1:
The patent merges multiple camera image streams into a single file, reducing the complexity of managing multiple separate files. The unified file structure with sequential frame arrangement and metadata indexing simplifies file management operations while significantly reducing the processing load on the monitoring device, as it needs to handle only one file instead of multiple files, thereby addressing both device complexity and power consumption concerns.
Data Source
AI summary
A data management device and a method of managing data are provided. The data management device includes a communication interface configured to receive image data from cameras, and a data manager configured to sort predetermined cameras among the cameras into a group, and record, among the received image data, image frames that are received from the predetermined cameras sorted into the group, in a single group file.
