Vehicle Instrument 3D Display With Predictive View-Angle Caching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Naked eye 3D displays in vehicle instruments experience delayed refresh responses due to head movement, causing operator dizziness and reduced display effectiveness.
Innovation Solution
A method that collects real-time operator eye position and behavior information to predict deviation intervals, generating and caching viewing angle images, which compensates for the real-time visual interweaving image display, reducing refresh time from 100 ms to 30 ms.

Engineering Contradiction Analysis
1Illumination intensity
If naked eye 3D display is applied to vehicle instruments, then realism and stereoscopic effect are improved, but display refresh response deteriorates when operator moves head
Solution Approach 1:
The system pre-calculates and caches 3D display images for multiple possible head positions before the operator actually moves. When head movement is detected, the corresponding pre-calculated image is immediately displayed without requiring real-time recalculation, thus maintaining high refresh rates while preserving 3D effects
Solution Approach 2:
The system dynamically adjusts the display refresh strategy based on detected head movement. When head position changes are detected, the system switches from real-time rendering to cached image display, optimizing the balance between 3D quality and refresh speed according to actual operational conditions
2Measurement precision
If real-time rendering is used to maintain display quality during head movement, then image quality is improved, but processing time increases causing dizziness
Solution Approach 1:
High-quality 3D images for various head positions are pre-rendered and cached in advance. During operation, the system simply retrieves the appropriate cached image based on detected head position, avoiding real-time rendering delays while maintaining image quality
Solution Approach 2:
Instead of generating new high-quality images in real-time, the system creates copies of pre-rendered images for different head positions and stores them in cache. When head movement occurs, the appropriate copy is immediately displayed, eliminating processing time while preserving visual quality
