AR Head-Mounted Display for Vehicle Occluded Area Correction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for enhancing a vehicle occupant's field of vision by projecting images onto non-transparent vehicle parts, such as A-pillars, face challenges in achieving seamless and artifact-free transitions at the edges of these parts, leading to discomfort and safety risks, especially during reversing or turning.
Innovation Solution
A device and method utilizing a head tracker, multiple cameras, and a processing unit to determine and correct the field of view, allowing for precise reproduction of occluded image sections on a head-mounted display, ensuring accurate alignment and perspective matching with the occupant's view.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If images are projected onto non-transparent vehicle parts to enhance field of vision, then obscured areas become visible, but seamless transitions and artifact-free display at edges cannot be achieved
Solution Approach 1:
The patent replaces physical projection onto vehicle parts with a virtual reality system using head-mounted displays and digital image processing. Cameras capture images of obscured areas, and a processing unit generates perspective-corrected virtual images that are displayed through transparent or semi-transparent lenses, eliminating physical projection artifacts and enabling seamless transitions at edges.
Solution Approach 2:
The patent applies perspective transformation and geometric correction algorithms to adjust the captured images according to the occupant's head position and viewing angle. By dynamically changing the display parameters based on tracked head movements, the system achieves accurate alignment at edges and seamless transitions between visible and previously obscured areas.
2Measurement precision
If a head-mounted display is used to show corrected images, then perspective accuracy improves, but device complexity increases
Solution Approach 1:
The head-mounted display serves multiple functions: it tracks the occupant's head position, displays the virtual reality images, and provides the transparent/semi-transparent interface for viewing. The processing unit integrates image capture, perspective correction, and real-time rendering functions. This multi-functionality justifies the increased device complexity by delivering superior perspective accuracy and seamless display.

AI summary
The invention relates to a device for reproducing data in an augmented reality in a vehicle, with a head tracker. Said device comprises a first camera (3) for filming an outer region of the vehicle, a second camera (4) for filming the field of view of the passenger of the vehicle, a processing device (5) comprising a first module for determining first data based on the detected field of view and the outer area; a second module for determining second data based on the filmed field of view which characterizes at least one concealed image section (6); a third module for comparing the first data to the second data; a fourth module for correcting the first date based on the second data; and a head-mounted device (HMD) (8), designed to reproduce the corrected first data as augmented reality in at least one concealed image section.
