Gate Access Matching Using Distance-Based Passage Sequence
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing walk-through face authentication systems struggle with determining the sequence of individuals passing through a gate, leading to difficulties in smoothly allowing access.
Innovation Solution
An information processing device that extracts feature values from captured images, estimates distances to individuals, and executes matching determinations based on these values to control gate access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If face authentication is performed on all persons in a line at the gate, then security checking is improved, but determining the correct passage sequence becomes difficult
Solution Approach 1:
The system segments the authentication process by distance zones. Persons are divided into groups based on their distance from the gate (first distance, second distance greater than first). Different authentication strategies are applied to each segment: comprehensive face authentication for closer persons and distance-based sequence determination for farther persons. This segmentation resolves the contradiction by applying security checks only where necessary while using simpler methods elsewhere.
Solution Approach 2:
The system performs preliminary distance estimation and grouping before final authentication decisions. By pre-categorizing persons into distance-based groups and identifying the closest person in advance, the system prepares the authentication sequence beforehand. This preliminary action eliminates the need for complex real-time sequence determination during authentication, improving both security and operational ease.
2Productivity
If the gate opens and closes frequently to accommodate multiple persons, then passage throughput is improved, but smooth passage becomes difficult due to sequence determination issues
Solution Approach 1:
The system determines the passage sequence in advance based on distance estimation before the gate operation. By identifying who should pass next based on their position in the line (closest person first), the system prepares the passage sequence beforehand. This allows the gate to open and close efficiently for the correct persons in the correct order, improving throughput while maintaining smooth passage without sequence confusion.
Solution Approach 2:
The system continuously monitors person positions and updates the passage sequence determination based on real-time distance measurements. As persons move toward the gate, the system receives feedback on their positions and adjusts the authentication and passage sequence accordingly. This feedback mechanism ensures that the gate operates smoothly with the correct persons while maintaining high throughput.

AI summary
An information processing device of the present invention includes: an image processing means that extracts a feature value of an object within a captured image obtained by capturing a pre-passing region of a gate, and stores matching information relating to matching of the object based on the feature value; a distance estimating means that estimates a distance from the gate to the object within the captured image; and a matching means that executes matching determination based on the estimated distance and the stored matching information of the object that the distance has been estimated.
