RFID-Linked Video Management for Dynamic Target Scene Retrieval
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Accessing specific scenes within videos recorded in dynamic environments where targets change over time or items and people move frequently is difficult due to the inefficiency of existing image recognition methods.
Innovation Solution
A video management system that utilizes RFID tags to associate video footage with tag identification information, allowing for the extraction of specific scenes by storing reading results in a database, enabling direct access to portions of videos corresponding to tag reading times.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If image recognition is used to find specific targets in videos, then automatic judgment can be performed, but it requires the target appearance to be known and unchanged which is not satisfied in dynamic environments
Solution Approach 1:
The patent introduces RFID tags as intermediary objects attached to management targets. Instead of directly recognizing target appearances in videos, the system uses RFID tags to emit identification information that mediates the connection between the video data and target identification. This intermediary approach allows automatic judgment without requiring the target appearance to remain unchanged, as the RFID tag provides a stable identification marker regardless of appearance variations.
2Quantity of substance
If more videos are recorded to cover dynamic environments, then more scenes are captured, but it becomes more difficult to access desired scenes
Solution Approach 1:
The patent implements a feedback mechanism where RFID tag reading results are continuously monitored and used to automatically extract and present relevant video scenes. When a specific RFID tag is detected, the system automatically retrieves and displays the corresponding video portion without requiring manual search through multiple recorded videos. This feedback loop between RFID detection and video extraction maintains ease of operation even as the number of recorded videos increases.
3Device complexity
If manual search through videos is performed to find specific scenes, then no additional technology is needed, but it requires exhaustive examination which is time-consuming
Solution Approach 1:
The patent applies preliminary action by pre-attaching RFID tags to management targets before video recording begins. This preliminary placement of identification markers enables automatic scene extraction later without requiring exhaustive manual search. The RFID tags are prepared in advance and remain attached to targets throughout the recording period, allowing rapid retrieval of specific scenes when needed.

Function Achieved in This Case
Facilitates easy access to scenes containing specific targets without exhaustive video examination, functioning effectively even in environments where appearances change, and reducing the need for image recognition.
Implementation Method 1

AI summary
There is provided a video management system for managing a video of a real space captured by a capturing apparatus, including: a first reading unit configured to emit an electromagnetic wave to a tag reading range and read information that is sent back from a radio frequency identification (RFID) tag utilizing energy of the electromagnetic wave; a first RFID tag that stores first tag identification information; and a data management unit configured to cause a database to store a reading result by the first reading unit in association with the video so that a portion in the video captured by the capturing apparatus corresponding to a time at which the first tag identification information has been read from the first RFID tag by the first reading unit is able to be extracted.
