Passenger Face Search via Security Check Image Registration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing non-boarded passenger search systems in airport terminal buildings face inefficiencies due to limited opportunities for photographing passenger images, which can result in unsuitable registration images and passenger discomfort, leading to delayed identification of non-boarded passengers and potential missed flights.
Innovation Solution
A system that registers face images of scheduled passengers before a predetermined passage point, compares them in real-time, associates flight numbers with face images, and presents position information between the passage point and boarding gate, allowing for efficient identification of non-boarded passengers without requiring them to be aware of or pose for the cameras.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If passenger images are photographed only when identification number is acquired at the boarding lobby, then the system complexity is reduced, but the image registration reliability deteriorates because passengers may be looking down or moving too fast for suitable photographing
Solution Approach 1:
The patent applies preliminary action by photographing passenger images at the security check point before passengers reach the boarding lobby. This advance photographing ensures that images are captured when passengers are stationary and facing forward, guaranteeing suitable image quality for registration before the search process begins.
2Reliability
If passengers are required to look toward the photographing device or walk slowly for image capture, then the image registration reliability improves, but the passenger comfort deteriorates and boarding efficiency decreases
Solution Approach 1:
The system captures images preliminarily at the security check point where passengers naturally face forward during identity verification, eliminating the need to alter their behavior later. This resolves the contradiction by obtaining reliable images without requiring passengers to pose or slow down during the boarding process.
Solution Approach 2:
The system utilizes the existing security check process where passengers naturally present their faces for identification. The photographing device captures images during this mandatory self-verification step, so passengers do not need to perform additional actions or change their natural behavior, maintaining both reliability and comfort.
3Reliability
If multiple photographing opportunities are provided before the passage point, then the image registration reliability improves, but the loss of time increases due to additional processing
Solution Approach 1:
The system performs image capture and registration preliminarily at the security check point before the actual search begins. By establishing the image database in advance, the system eliminates the need for real-time image capture during the search process, thus improving reliability without adding time loss during operations.

AI summary
A non-boarded passenger search device which searches for a non-boarded passenger includes an image registration unit that registers image data of faces of a plurality of scheduled passengers photographed before a predetermined passage point; a determination unit that determines whether a scheduled passenger whose face is photographed at the passage point is registered in the image registration unit; when the face is photographed at the passage point is registered, a fight number registration unit that registers a flight number which the scheduled passenger is scheduled to board, in association with image data of the face; and a presentation unit that presents position information of the scheduled passenger, based on the image data of the face of the scheduled passenger, the flight number, image data of the face of the scheduled passenger and position information of the plurality of photographing points.
