Vehicle Face Recognition for Personalized Access and Startup
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle face authentication systems are limited in functionality, primarily using cameras for face recognition without integrating additional features or enhancing user convenience, especially in vehicle access and starting systems.
Innovation Solution
A vehicle system that includes a camera with an external field of view, a communicator, storage, and a controller to detect a remote controller, activate the camera based on proximity, and control electronic devices using personalized settings based on face recognition, allowing for enhanced user convenience and functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the camera is activated only for face authentication, then the system maintains simple operation and low energy consumption, but the functionality and user convenience are limited
Solution Approach 1:
The camera system is extended to perform multiple functions: face authentication, face recognition for personalization, and real-time monitoring. The controller determines whether to perform face authentication or face recognition based on detection results, allowing the same hardware to serve different purposes and improve overall system versatility without adding separate dedicated devices.
2Ease of operation
If the camera remains continuously active for monitoring, then real-time personalization control is achieved, but energy consumption increases
Solution Approach 1:
The camera operates in periodic intervals rather than continuously. It is activated when the controller detects a specific object or condition, performs the necessary face recognition or authentication, and then deactivated. This periodic activation pattern maintains real-time monitoring capability when needed while significantly reducing overall energy consumption compared to continuous operation.
Solution Approach 2:
The controller performs preliminary detection to determine whether face authentication or face recognition should be performed before activating the camera. This preliminary action allows the system to prepare and only activate the camera when necessary, avoiding unnecessary energy consumption while ensuring user convenience is maintained when conditions warrant activation.
3Measurement precision
If face recognition is performed with high similarity threshold, then authentication accuracy is improved, but the system becomes less adaptable to variations in user appearance
Solution Approach 1:
The system uses different similarity threshold parameters for different purposes: a first similarity threshold for face authentication and a second similarity threshold for face recognition. By adjusting these parameter values according to the specific task requirements, the system achieves both high accuracy for authentication and adequate adaptability for recognition, resolving the contradiction between precision and versatility.

AI summary
A vehicle providing a personalization setting function using a camera used for a face authentication system includes: a camera configured to have a field of view facing an outside of the vehicle; a communicator configured to wirelessly communicate with a remote controller of the vehicle; a storage storing a plurality of reference face images and a personalization setting corresponding to each of the plurality of reference face images; and a controller electrically connected to the camera, the communicator and the storage and configured to: detect the remote controller based on a signal received from the remote controller through the communicator; activate the camera based on the remote controller being detected; and control at least one electronic device of the vehicle according to a personalization setting corresponding to a first reference face image among the plurality of reference face images, based on a similarity score between the first reference face image and a first image obtained from the camera being greater than a first threshold value.
