Vehicle AR Head-Up Display Viewpoint Alignment Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Augmented reality head-up displays in vehicles fail to accurately match projected information with the driver's viewpoint position due to variations in the driver's physical condition or posture, leading to misalignment of virtual images on the windshield.
Innovation Solution
A vehicle display system with a user input device, head-up display, and controller that adjusts the projection position of augmented reality contents based on driver viewpoint information and directional offsets, allowing for real-time correction through a user interface screen, enabling precise alignment of virtual images with the road.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a fixed projection position is used for augmented reality contents, then the system structure is simple, but the alignment accuracy with the driver's viewpoint deteriorates due to variations in driver's physical condition or posture
Solution Approach 1:
The patent implements dynamic adjustment of the projection position based on detected driver viewpoint information. The head-up display system changes the projection position in real-time according to the driver's physical condition and posture, transforming a static system into a dynamic one that adapts to varying conditions, thereby maintaining alignment accuracy without requiring complex manual calibration for each driver
Solution Approach 2:
The system automatically detects the driver's viewpoint and self-adjusts the projection position without requiring manual intervention or complex external calibration equipment. The head-up display system serves itself by using its own detection capabilities to correct alignment issues, simplifying the overall system while improving accuracy
2Measurement precision
If the projection position is adjusted for each driver, then the alignment accuracy improves, but the ease of operation deteriorates due to additional adjustment steps
Solution Approach 1:
The system automatically detects the driver's viewpoint and self-adjusts the projection position without requiring manual intervention or complex external calibration equipment. The head-up display system serves itself by using its own detection capabilities to correct alignment issues, simplifying the overall system while improving accuracy
Solution Approach 2:
The system implements a feedback mechanism where the detected driver viewpoint information is continuously used to adjust and optimize the projection position. This closed-loop approach ensures accurate alignment while maintaining ease of operation, as the system automatically makes corrections based on real-time feedback from driver detection

AI summary
A display system of a vehicle, and a control method thereof includes: a user input device; a head-up display configured to project a virtual image including augmented reality contents and to adjust a projection position of the augmented reality contents according to predetermined driver viewpoint information and left and right direction offset; and a controller configured to correct the driver viewpoint information or the left and right direction offset according to a control input received through the user input device, wherein the left and right direction offset indicates a degree to which the augmented reality contents are shifted left or right.
