Facial Recognition Gate Barrier Tracking System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gate apparatuses require passengers or visitors to stop in front of a camera for face authentication, leading to delays as staff must manually capture face images, hindering quick passage through security screening areas.
Innovation Solution
An information processing apparatus that captures initial images of multiple faces, performs facial recognition, detects and tracks body regions associated with authenticated individuals, and controls barriers to allow passage without requiring continuous facial recognition, enabling individuals to pass through without stopping in front of the camera.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If staff manually operate the camera to capture face images for authentication, then authentication accuracy is ensured, but passage speed decreases due to delays
Solution Approach 1:
The system performs preliminary face authentication by capturing and verifying face images before the passenger reaches the barrier. Multiple cameras capture face images at different positions, and the authentication is completed in advance, allowing the barrier to be pre-positioned for quick opening without requiring manual intervention during the actual passage
Solution Approach 2:
The manual mechanical operation of staff controlling the camera is replaced with an automated optical system using multiple cameras and image processing algorithms. The system automatically captures, transmits, and processes face images through communication networks, eliminating the need for manual camera operation while maintaining authentication reliability
2Reliability
If passengers stop in front of the camera for face authentication, then authentication can be performed, but time is lost due to stopping
Solution Approach 1:
Authentication is performed in advance as passengers approach the gate area. The system captures and verifies face images before passengers need to stop, completing the authentication process proactively so that the barrier is ready for immediate opening without requiring passengers to pause their movement
Solution Approach 2:
The authentication process continues seamlessly as passengers move through the gate area. Multiple cameras capture images at different positions, and the system processes these images continuously without interruption, maintaining the flow of passengers while ensuring authentication is completed at each stage
3Reliability
If multiple cameras are used to capture images at different positions, then authentication reliability is improved, but device complexity increases
Solution Approach 1:
Multiple cameras positioned at different locations are merged into a unified authentication system. The cameras work together to capture images at various stages, and their data is integrated through the communication network and processing system, achieving enhanced reliability while managing complexity through coordinated operation rather than separate independent systems
Solution Approach 2:
The camera system serves multiple functions: capturing face images for authentication, tracking passenger movement through the gate area, and providing verification at different positions. This multi-functionality justifies the use of multiple cameras and reduces the need for separate dedicated devices for each function

AI summary
An apparatus includes a memory storing one or more instructions; and a processor configured to execute the one or more instructions to: obtain a first image including one or more faces captured at a first time by one or more cameras, each of the one or more faces corresponding to a person, among one or more persons; detect a first person, among the one or more persons, by performing facial recognition operation on the one or more faces in the image obtained from the camera; detect a body region corresponding to a face region of the first person; track the body region in a second image captured by the one or more cameras at a second time subsequent to the first time; and output information to control a bather to open based on a determination that the body region is approaching the barrier.
