Face Authentication Apparatus Head Tracking Flow Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing authentication technologies face challenges in efficiently and accurately authenticating individuals in dynamic environments, such as theme parks, airports, and offices, where multiple individuals need to be authenticated quickly and without disrupting the flow of people.
Innovation Solution
An authentication apparatus and method that includes an acquisition unit to capture images of a predetermined area, a tracking unit to track individuals based on their head position within the image, and a face authentication unit to perform authentication when the individual's face is within the image frame, ensuring efficient and accurate authentication even in crowded conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If face authentication is performed on all detected individuals in a crowded area, then authentication coverage is improved, but processing time and system complexity increase significantly
Solution Approach 1:
The system performs preliminary actions by detecting and tracking individuals before authentication. The tracking unit continuously monitors detected individuals and prepares their facial data, so when authentication is needed, the processing is already partially complete, reducing actual authentication time
Solution Approach 2:
The system dynamically adjusts authentication processing based on real-time conditions. The control unit determines whether to perform authentication based on tracking results and current system state, allowing flexible resource allocation that balances coverage with processing speed
2Measurement precision
If face authentication is performed continuously on moving individuals, then authentication accuracy is improved, but the flow of people is disrupted
Solution Approach 1:
The system allows individuals to pass through naturally without stopping or special actions. The tracking unit automatically follows and monitors individuals as they move, and authentication is performed in the background without requiring the individual to pause or change their natural movement pattern
3Reliability
If tracking is performed on all detected individuals, then authentication reliability is improved, but device complexity increases
Solution Approach 1:
The system merges detection and tracking functions into a unified process. The tracking unit builds upon the detection results and maintains continuous monitoring of identified individuals, combining multiple functions into an integrated system that reduces overall complexity while maintaining reliability

AI summary
Provided are: an acquisition unit that acquires an image including a predetermined area through which an authentication target person passes; a tracking image that tracks the authentication target person on the basis of a tracking area of the authentication target person including a head of the authentication target person in the image; and a face authentication unit that performs face authentication on the authentication target person, when a face of the authentication target person is included in the image while the tracking unit tracks the authentication target person.
