Baggage Search Using RFID and Image Collation for Fast Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing baggage search methods in airports are time-consuming and prone to errors due to visual searches and reliance on RF baggage tags, which do not sufficiently reduce search time or prevent mistakes.
Innovation Solution
A baggage search method utilizing an operator terminal equipped with a search information acquisition unit, tag communication unit, camera, and processing unit for image and ID collation, combined with an orientation estimation unit to quickly locate and verify baggage using radio tags, reducing search time and minimizing errors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If visual search based on baggage image is used, then search time is reduced compared to searching only by baggage number, but mistakes may occur and search time is not shortened enough
Solution Approach 1:
The patent segments the baggage identification process into multiple independent verification steps: first reading the RFID tag ID, then capturing an image of the baggage, and finally collating both with stored search target information. This segmentation allows each step to contribute to the overall accuracy while maintaining efficiency.
Solution Approach 2:
The system implements feedback by collating the read ID and captured image with pre-stored search target information, providing verification feedback to confirm correct baggage identification before proceeding with unloading operations.
2Area of stationary object
If RFID tag reading is used to obtain loading position information, then search area can be narrowed down, but search time is not sufficiently reduced
Solution Approach 1:
The patent adds the image recognition dimension to the traditional RFID-based search method. By combining spatial information from RFID tags with visual verification through image capture and collation, the system transforms a one-dimensional search (by location) into a two-dimensional verification process (location + visual identification).
3Reliability
If multiple verification steps are implemented, then accuracy of baggage identification is improved, but device complexity increases
Solution Approach 1:
The operator terminal is designed as a multi-functional device that integrates RFID tag reading capabilities, image capture functionality, and information collation processing. This universal device consolidates multiple verification functions into a single portable unit, reducing overall system complexity while maintaining high identification accuracy.
4Productivity
If image capture and collation is performed, then search speed is improved, but use of energy increases due to camera and processing operations
Solution Approach 1:
The system performs image capture and collation only when necessary - specifically when searching for NO SHOW passenger baggage that requires verification. This partial action approach avoids continuous energy-consuming operations while maintaining high search speed when needed.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The method enables rapid identification of target baggage by image and ID matching, reducing search time and minimizing errors through precise orientation estimation and ID verification, while also optimizing the use of cameras and tag readers.
Implementation Method 1
an information acquisition process in which the search information acquisition unit acquires search target information including a search target image which is a photographed image of the search target baggage and target ID read by communication from the radio tag attached to the search target baggage
Implementation Method 2
a camera which photographs the search target baggage

AI summary
A baggage search method including following processes: an information acquisition process for acquiring a search target information including a search target image of a search target baggage and a target ID stored in a radio tag attached to the search target baggage, an image collation process for collating a pictured area that contains at least a part of a baggage group containing the search target baggage selected by an operator with the search target image included in the search target information by a processing unit, a displaying process for displaying the pictured area highlighting a baggage area in which the target baggage is included and an ID collation process which the processing unit collates an ID of the radio tag read by the tag communication unit of an operator terminal operated by the operator with the target ID included in the search target information.
