Vehicle Display Image Warping for Distortion-Free Angled Viewing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle display systems distort images when viewed from inclined angles, leading to discomfort for occupants.
Innovation Solution
A system that includes an occupant monitoring unit to track the position and gaze of vehicle occupants, generating control commands for image warping to maintain a distortion-free view by adjusting the image based on the occupant's position and gaze, ensuring the image appears frontal without distortion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If an image is displayed on a vehicle display from a fixed angle, then the display structure is simple, but the image becomes distorted when viewed from inclined angles
Solution Approach 1:
The patent implements dynamic image warping that adapts to the occupant's viewing angle and position. The control command generation unit dynamically adjusts the image geometry based on real-time occupant monitoring data, transforming the static display into a dynamic system that maintains image quality across different viewing conditions.
Solution Approach 2:
The system changes image parameters (geometry, orientation, distortion level) based on occupant position and gaze information. By modifying these parameters dynamically, the system resolves the contradiction between maintaining simple display structure and preventing image distortion at inclined viewing angles.
2Ease of operation
If image warping is applied to eliminate distortion, then viewing comfort is improved, but the system complexity increases due to additional monitoring and processing units
Solution Approach 1:
The control command generation unit serves multiple functions: it receives occupant monitoring information, determines viewing angles, calculates warping parameters, and generates control commands. This multi-functionality reduces the need for separate dedicated components, thereby mitigating the increase in system complexity while achieving distortion-free viewing.
Solution Approach 2:
The control command generation unit acts as an intermediary between the occupant monitoring unit and the warped image display unit. It processes monitoring data and translates it into appropriate display control commands, simplifying the overall system architecture by providing a centralized control mechanism rather than requiring direct complex interactions between monitoring and display components.
3Manufacturing precision
If the display adjusts image based on real-time occupant monitoring, then image distortion is eliminated, but the processing time and computational load increase
Solution Approach 1:
The system pre-calculates and stores warping control commands for different occupant positions and viewing angles. When an occupant's position is detected, the system retrieves the pre-prepared control command rather than calculating it in real-time, significantly reducing processing time while maintaining high image accuracy.
Solution Approach 2:
The system continuously monitors occupant position and gaze information, using this feedback to adjust the image warping parameters. This closed-loop feedback mechanism ensures high image accuracy by constantly adapting to the occupant's viewing conditions while optimizing processing efficiency through incremental adjustments rather than complete recalculations.
