Vehicle AR Display Positioning With Unified Posture Correction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Position displacement of images in vehicle-based augmented reality displays occurs due to changes in vehicle posture caused by passenger load, fuel levels, and road conditions, leading to discomfort for drivers when corrections are made separately for stationary and traveling states.
Innovation Solution
A display system that includes a posture detection device, a posture estimator, a reference position setting device, and a correction processing device to continuously adjust the display position of virtual images based on real-time vehicle posture variations, ensuring accurate alignment with the vehicle's surroundings without causing noticeable shifts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If separate corrections are made for stationary and traveling states, then image position accuracy is improved for each state, but driver discomfort increases due to noticeable position shifts during state transitions
Solution Approach 1:
The patent merges the correction operations for stationary and traveling states into a unified continuous correction process. The posture detection device continuously monitors vehicle posture, and the correction amount is calculated and applied without interruption during state transitions, eliminating noticeable position shifts and driver discomfort while maintaining image position accuracy.
Solution Approach 2:
The patent implements dynamic correction by continuously adjusting the image display position based on real-time vehicle posture detection. The correction amount is dynamically calculated according to the detected posture variation amount, allowing the system to adapt smoothly to changing vehicle conditions during transitions between stationary and traveling states.
2Stability of the object's composition
If continuous correction is applied during vehicle operation, then image position stability is improved, but system complexity increases due to multiple detection and correction components
Solution Approach 1:
The patent employs a universal correction mechanism that handles both stationary and traveling states through a single integrated system. The posture detection device and correction processing device work together to provide continuous correction functionality across all vehicle operating conditions, reducing the need for separate correction systems for different states.
Solution Approach 2:
The patent maintains continuous correction action by constantly detecting vehicle posture and applying correction amounts without interruption. This continuous operation ensures image position stability throughout all vehicle states while using a streamlined system that avoids the complexity of multiple discrete correction mechanisms.
