Solution Overview

Problem

The existing gate apparatuses face challenges in allowing users to pass through quickly due to difficulties in face authentication when a passport is placed on a reader in front of a face authentication device.

Innovation Solution

The gate apparatus includes biometrics information acquisition units to capture biometric data from users approaching or stopped in front of an exit gate door, with a door control unit that opens the gate based on biometric comparisons, accommodating various user orientations and conditions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If face authentication is performed using a camera positioned in front of the passport reader, then authentication accuracy is improved, but the time required for users to pass through the gate increases

Engineering Contradiction:
Improveauthentication accuracyVSAvoidpassage time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The patent introduces a second camera positioned at a different spatial location (above and behind the passport reader) to capture face images from a different dimension. This multi-dimensional approach allows simultaneous acquisition of face images from multiple angles, enabling authentication without requiring users to stop or reposition, thus resolving the contradiction between authentication accuracy and passage time

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The system performs preliminary face image capture using the second camera positioned above the passport reader, which can capture images as users approach without requiring them to stop. This preliminary action allows the authentication process to begin earlier and proceed without interrupting user flow, reducing passage time while maintaining authentication accuracy through subsequent verification

Inventive Principle:
Principle #10Preliminary action

2Reliability

If users must stop in front of the gate to allow face capture, then authentication reliability is improved, but productivity of the gate system deteriorates

Engineering Contradiction:
Improveauthentication reliabilityVSAvoidgate throughput
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent enables continuous face image capture by positioning the second camera above the passport reader, allowing images to be acquired as users walk through without interruption. This continuous action maintains authentication reliability through multiple capture opportunities while preserving gate throughput by eliminating stops and delays in the user flow

Inventive Principle:
Principle #20Continuity of useful action

AI summary

A gate apparatus includes: an exit gate door; a first biometrics information acquisition unit that acquires, from a user who moves toward the exit gate door in a closed state, first target biometrics information to be compared with registered biometrics information registered in advance; a second biometrics information acquisition unit that acquires second target biometrics information to be compared with the registered biometrics information from the use who stops in front of the exit gate door when there is no matching in a comparison between the first target biometrics information and the registered biometrics information or the comparison is unable to be performed; and a door control unit that opens the closed exit gate door in accordance with a result of a comparison between the first target biometrics information or the second target biometrics information and the registered biometrics information.
