Vehicle Face Authentication Image Correction via Windshield Attributes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional face authentication systems face challenges in accurately authenticating individuals when the face image is captured through vehicle components like windshields and side glasses, leading to discrepancies and incorrect authentication due to varying colors and angles.
Innovation Solution
An information processing apparatus and method that acquires user and vehicle identification information, and processes the authentication face image based on vehicle attributes such as windshield color, size, and position of components to generate a processed authentication face image, which reflects the vehicle's attributes, thereby reducing discrepancies and improving authentication accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If face authentication is performed using a pre-registered authentication face image, then authentication speed is improved, but authentication accuracy deteriorates when the face image is captured through vehicle components like windshields and side glasses due to varying colors and angles
Solution Approach 1:
The patent applies preliminary action by pre-registering not only the authentication face image but also the vehicle attribute information (windshield color, side glass color, component positions) during the registration phase. This allows the system to prepare corrected authentication face images in advance that account for the specific vehicle's optical characteristics, enabling both fast authentication and high accuracy when comparing captured images against these pre-prepared references
Solution Approach 2:
The patent changes parameters by adjusting the authentication face image based on vehicle attributes such as windshield color, side glass color, and component positions. The image processing unit modifies the pre-registered authentication face image to reflect these parameter variations, creating a corrected version that matches what the camera would capture through the vehicle's components, thereby resolving the accuracy issue while maintaining speed
2Measurement precision
If the authentication face image is processed to reflect vehicle attributes, then authentication accuracy is improved, but processing complexity increases
Solution Approach 1:
The system performs the complex image processing in advance during registration, storing the corrected authentication face images for later use. This preliminary processing eliminates the need for complex real-time processing during authentication, maintaining simplicity and speed while achieving high accuracy through pre-computed corrections based on vehicle attributes
Solution Approach 2:
The patent creates a corrected copy of the authentication face image that reflects the vehicle's optical characteristics. Instead of modifying the original image or performing complex processing during authentication, the system generates and stores a corrected version that already incorporates the vehicle attribute effects, simplifying the authentication process to a direct comparison
