Gate Apparatus Facial Recognition and Body Tracking for Access Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gate apparatuses face challenges in efficiently managing the passage of multiple individuals through security screening areas, particularly in determining authorized access and handling unauthorized persons while maintaining security and throughput.
Innovation Solution
A system comprising cameras and an information processing apparatus that performs facial recognition and body tracking, allowing authorized individuals to pass through while maintaining the gate in an open state and closing it for unauthorized persons, using a combination of facial recognition and body region association to manage access without repeated authentication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If facial recognition authentication is performed for each person passing through the barrier, then security is improved, but processing time and system complexity increase
Solution Approach 1:
The system performs facial recognition authentication in advance when persons are at the first area before the barrier. The processor determines authorization status before the persons reach the barrier, so that when persons arrive at the barrier, the authentication result is already available and the barrier can be controlled immediately without repeated authentication delays
Solution Approach 2:
The barrier control state is made dynamic based on authentication results. The barrier remains open for authorized persons who have been authenticated, and only closes when unauthorized persons are detected. This dynamic adjustment allows continuous passage for authorized persons while maintaining security
2Productivity
If facial recognition is performed on multiple persons simultaneously, then throughput is improved, but measurement precision and authentication reliability may deteriorate
Solution Approach 1:
The system segments the authentication process by first detecting and identifying each person individually in the image, obtaining face images for each detected person, and then performing facial recognition on each person's face image separately. This segmentation ensures that each person is authenticated accurately even when multiple persons are present, while the parallel processing of multiple persons maintains high throughput
3Productivity
If the barrier remains open for authorized persons, then productivity is improved, but security control is weakened
Solution Approach 1:
The system continuously monitors the area before the barrier using cameras and performs real-time facial recognition on detected persons. Based on the authentication feedback, the processor dynamically adjusts the barrier control - keeping it open for authorized persons and closing it when unauthorized persons are detected. This continuous feedback loop maintains both high throughput for authorized persons and strict security control

AI summary
A gate apparatus includes a memory storing one or more instructions; and a processor configured to execute the one or more instructions to: obtain an image including a plurality of persons captured by one or more cameras, each of the plurality of persons present at a first area in advance of a barrier, process the image to determine whether each of the plurality of persons at the first area is authorized to proceed through the barrier and control the barrier, based on a status that the plurality of persons are identified as being authorized or unauthorized.
