Vehicle Face Authentication With Guided Registration and Window Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle systems lack effective user authentication methods that prevent theft by ensuring secure door and engine control, particularly when the remote controller is left inside the vehicle, and require user-friendly registration processes for all age groups.
Innovation Solution
An authentication device with a face recognition system that includes a communication module, face recognition processor, and authentication processor, which guides users through face registration, adjusts window glass openings based on weather and user height, and performs user authentication using an authentication camera and vehicle terminal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If face registration is performed with window glass closed for security, then vehicle security is improved, but user registration convenience deteriorates
Solution Approach 1:
The window glass dynamically changes its state between closed and open based on the registration phase. During face registration, the window automatically opens to allow external camera access, then closes after registration completes, providing both security and functionality through dynamic state change
Solution Approach 2:
The window glass opens in advance before the face registration process begins and remains open throughout the registration procedure. This preliminary action ensures that the camera can capture the user's face without obstruction, and the window closes after registration to restore security
2Measurement precision
If window glass is opened fully for face registration, then registration accuracy is improved, but rainwater intrusion risk increases
Solution Approach 1:
The window glass opening degree is dynamically adjusted based on weather conditions. During rainy weather, the window opens to a limited degree (e.g., 30-50mm) sufficient for camera access but restricted to prevent rainwater intrusion, while in clear weather it opens fully for optimal registration accuracy
Solution Approach 2:
The window glass transitions from a static closed state to a dynamically controlled opening state, with the opening degree adjusted in real-time based on rain sensor detection and registration progress, allowing the system to adapt to varying environmental conditions
3Ease of operation
If multiple display devices are used for face registration, then user guidance clarity is improved, but device complexity increases
Solution Approach 1:
Multiple display devices (instrument panel, head-up display, augmented reality glasses) serve the same face registration guidance function simultaneously, each presenting information in formats suitable for their display characteristics and user viewing contexts

AI summary
A vehicle includes an authentication camera provided on an exterior of a body of the vehicle, a vehicle terminal provided on an interior of the body and receiving a user input, an auxiliary display provided on the interior of the body and displaying an review view image, and a processor controlling, upon receipt of a face registration start command for a user, the vehicle terminal to display guide information for a face registration procedure, controlling the auxiliary display to display a guideline and image information acquired by the authentication camera, acquiring outline information of a face image based on the acquired image information, recognizing face information based on the acquired outline information of the face image and location information of the guideline, and registering the recognized face information as the face information of the user.
