HUD Facial Recording Alignment in Intelligent Vehicle Cockpits
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In intelligent vehicles, the misalignment between the camera and display positions in the cockpit leads to a poor user experience during biometric recognition, as users struggle to simultaneously face the camera and display, resulting in inconvenient information recording processes.
Innovation Solution
The method involves displaying prompt information on a head-up display to guide users in recording facial information, adjusting the face image based on the face attitude angle and position, and adjusting the display angle and height to ensure the information is presented directly in the user's line of sight, allowing for convenient facial information recording without needing to consider the camera and display positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the camera and display are positioned separately in the cockpit, then the device layout is flexible and installation is easier, but the user cannot face both the camera and display simultaneously, degrading the ease of operation
Solution Approach 1:
The patent introduces a head-up display (HUD) as an intermediary device to project the display interface onto the windshield or dashboard. This allows the display to appear at a position that aligns with the camera's field of view, enabling the user to face both simultaneously without physically moving between positions. The HUD acts as a mediator that reconciles the spatial separation between camera and display while maintaining installation flexibility.
2Device complexity
If the display position is fixed away from the camera, then the device structure is simpler, but the user experience during biometric recognition deteriorates due to the need to switch between facing the camera and viewing the display
Solution Approach 1:
The patent utilizes the windshield or dashboard surface as an additional display dimension by projecting the HUD interface onto it. This transforms the traditional planar display arrangement into a multi-dimensional configuration where the display can be virtually positioned at multiple locations simultaneously. The display information is projected onto the windshield in front of the user, creating a new spatial dimension that aligns with the camera's viewing angle while maintaining the physical display device at its original position.

AI summary
An information recording method includes obtaining image information; displaying prompt information on a head-up display based on the image information, where the prompt information is used to guide a user to record facial information; and obtaining the facial information.
