Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Naked eye 3D displays in vehicle instruments suffer from delayed refresh responses due to head movements, causing dizziness and affecting display quality.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If real-time rendering is used to generate 3D images according to eye position, then display accuracy is improved, but refresh speed deteriorates due to computational complexity
Solution Approach 1:
The patent pre-calculates and stores rendering results for different eye positions in a lookup table before actual display. When the eye position is detected, the system directly retrieves the pre-rendered image from the table rather than performing real-time rendering, thus achieving both high display accuracy and fast refresh speed.
Solution Approach 2:
The patent creates a copy of the rendering results and stores them in advance. Instead of generating new images during display, the system copies and retrieves pre-generated images from storage based on detected eye positions, eliminating real-time computational delays while maintaining image quality.
2Ease of operation
If the display system tracks and adapts to eye position changes, then viewing comfort is improved, but system complexity increases due to additional sensors and processing
Solution Approach 1:
The patent makes the eye position detection capability universal by integrating it into the existing display system framework. The same detection mechanism serves multiple purposes: tracking eye position for image retrieval, determining viewing distance, and adjusting display parameters, thereby improving viewing comfort without proportionally increasing system complexity.
Solution Approach 2:
The system uses the display device's own resources (processing power, existing sensors) to perform eye position detection and image retrieval. Rather than adding entirely separate complex subsystems, the display system serves itself by utilizing its inherent capabilities to track and adapt to user eye movements.

AI summary
The present application relates to the field of naked eye 3D technology, provides a method and a device for naked eye 3D displaying a vehicle instrument, which includes: collecting a real-time eye position of an operator in a real time, generating a corresponding real-time visual interweaving image according to the real-time eye position, and displaying the real-time visual interweaving image on a display interface; identifying whether the operator is engaged in human behavior, if so, obtaining human behavior information of the operator; predicting a deviation interval of the operator according to the human behavior information, and generating and caching a viewing angle image set corresponding to the deviation interval; and compensating in response to the real-time visual interweaving image on the display interface according to the viewing angle image set. Thus, the problem of operator dizziness caused by untimely refresh of naked eye 3D can be avoided, and the display effect of naked eye 3D is improved.
