Vehicle HUD Projection Alignment Using Driver Eye Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Head-Up Displays (HUDs) require manual adjustment of gears, which is inefficient and can distract drivers, posing safety risks due to the need for attention during driving.
Innovation Solution
An automatic system that adjusts the HUD projection position based on real-time facial feature detection, determining the user's facial orientation and eye positions to ensure the display is aligned with the forward driving direction, using a linear regression algorithm to map eye positions to adjustable gears.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual adjustment of HUD gears is used, then the projection position can be changed, but the adjustment efficiency is low and driver attention is distracted
Solution Approach 1:
The system performs self-adjustment by automatically detecting driver facial features and eye positions, then autonomously calculating and adjusting the HUD projection position without requiring manual intervention from the driver
Solution Approach 2:
The manual mechanical adjustment process is replaced with an automated optical-detection-and-calculation system that uses facial feature detection and linear regression algorithms to determine the optimal projection position
2Ease of operation
If manual adjustment of HUD gears is used, then the projection position can be changed, but driving safety is compromised due to distracted attention
Solution Approach 1:
The HUD system adjusts itself automatically based on real-time detection of driver facial orientation and eye positions, eliminating the need for driver intervention and ensuring continuous safety monitoring
Solution Approach 2:
The system continuously monitors driver facial features and eye positions, providing real-time feedback to automatically adjust the projection position, ensuring the display remains optimized without distracting the driver
3Adaptability or versatility
If multiple adjustable gears are provided, then the projection position can adapt to different gestures, but the device complexity increases
Solution Approach 1:
The system dynamically adjusts the projection position based on real-time detection of driver gestures and eye positions, allowing the HUD to adapt to different driving scenarios without requiring multiple fixed adjustment mechanisms
Solution Approach 2:
The projection position parameters are automatically changed based on detected facial orientation angles and eye position coordinates, enabling the system to adapt to different gestures through parameter optimization rather than mechanical gear changes

AI summary
Disclosed are an information display method and apparatus, a device, a storage medium, a computer program product, a computer program, and a vehicle. The information display method comprises: acquiring a face image of a target user; performing face feature detection on the face image to determine face feature information and eye feature information of the target user, the eye feature information comprising target coordinate information corresponding to the eye position of the target user; determining whether the face feature information matches preset feature information; when the face feature information matches the preset feature information, determining a target projection position according to a correspondence between the target coordinate information and a projection position of a display system; and controlling the display system to perform information display in an area corresponding to the target projection position.
