Driver Face Authentication Using License Image Comparison
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing driver confirmation systems for vehicles do not effectively ensure that only legitimate drivers can operate the vehicle, leading to potential misuse.
Innovation Solution
A driver confirmation system that compares an image of a driver's license with a captured image of the driver's face using a camera and determination apparatus to authenticate the driver's identity, restricting or suspending vehicle operation if the images do not match.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If facial recognition is performed using only a captured image from the camera, then the system structure can be simplified, but the recognition accuracy deteriorates due to unknown camera angles and lighting conditions
Solution Approach 1:
The system performs preliminary actions by acquiring facial photograph images under controlled conditions before actual driving, and prepares multiple standardized facial images from different angles. These pre-prepared images serve as reference templates that improve recognition accuracy when comparing against captured images during driving, without requiring complex real-time adjustments
2Measurement precision
If multiple facial images from different angles are acquired and stored, then the recognition accuracy is improved, but the data processing complexity and time increase
Solution Approach 1:
Multiple facial images from different angles are acquired and processed in advance before actual driving operations. This preliminary processing creates a library of reference images that can be quickly compared during driving, reducing real-time processing time while maintaining high recognition accuracy
Solution Approach 2:
The system focuses processing on specific local features of the face by generating standardized facial images from different angles and selectively comparing relevant portions of captured images with corresponding angle-matched reference images, rather than processing entire images uniformly
3Ease of operation
If the system waits for the vehicle to stop to acquire facial photograph images, then the driver's attention can be focused on driving, but the time required for driver authentication increases
Solution Approach 1:
The system performs the time-consuming facial image acquisition and processing actions in advance, before the driving task begins. By completing authentication准备工作 beforehand, the actual driving phase requires only quick comparison operations, minimizing both attention distraction and authentication time
Solution Approach 2:
The system implements periodic facial recognition checks during driving at predetermined intervals or at specific locations. This periodic action allows the system to maintain authentication without requiring continuous processing, balancing driver attention requirements with security needs

AI summary
A determination apparatus (10) includes a first acquisition unit (21), a second acquisition unit (22), and a controller (23). The first acquisition unit (21) acquires a facial photograph image, included in a medium (13) holding the facial photograph image, as a first facial image. The second acquisition unit (22) acquires a captured image obtained by capturing an image of an imaging area, in which the face of a driver is assumed to be located, at a start of driving and/or during driving. The controller (23) extracts an image of the face of the driver as a second facial image from the captured image acquired from the second acquisition unit (22), compares the first facial image and the second facial image, and determines whether the driver is the person in the facial photograph image held by the medium (13).
