Stereoscopic Display Image Correction for User Position Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current stereoscopic display technologies fail to maintain a real stereoscopic impression when the user's location changes, as existing solutions are insufficient in correcting the virtual image location and size accordingly.
Innovation Solution
A method and apparatus that utilize distance measuring technology to obtain location change information of the user's spectacles and correct the image on the display screen, ensuring the virtual image remains unchanged by calculating and applying correction factors based on the user's movement, including amplification or reduction of image size and location adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If automatic tracking technology is used to adjust the display based on user position, then the stereoscopic impression is improved, but the device complexity increases
Solution Approach 1:
The patent changes display parameters (image position and size) based on detected user position changes. The system calculates correction amounts based on position detection results and applies these corrections to the displayed image, thereby maintaining accurate stereoscopic impression without requiring complex hardware adjustments.
Solution Approach 2:
The patent replaces mechanical adjustment systems (such as moving lenses or mirrors) with a computational approach. Instead of physically adjusting optical components to track user position, the system uses position detection combined with image parameter correction to achieve the same effect, significantly reducing device complexity.
2Reliability
If the display image is corrected in real-time based on user movement, then the stereoscopic impression is maintained, but the processing complexity increases
Solution Approach 1:
The patent pre-calculates correction amounts based on detected position changes before displaying the corrected image. By computing the necessary image parameter adjustments in advance based on position detection, the system ensures real-time correction without requiring complex real-time processing during image display.
Solution Approach 2:
The patent implements a feedback loop where user position is continuously detected, correction amounts are calculated based on position changes, and image parameters are adjusted accordingly. This closed-loop system maintains accurate stereoscopic impression by continuously adapting the display to user position while using efficient calculation methods to manage processing complexity.

AI summary
A control method and apparatus for stereoscopic display is provided. The method includes: obtaining the position change information of glasses of a user (s101); and then calibrating the image of display according to the position change information of glasses of the user (s102). The control apparatus includes: an obtaining module (101) which obtains the position change information of glasses of a user; and a calibrating module (102) which calibrates the image of display according to the position change information of glasses of the user. Compared with the prior art, the present invention can effectively solves the problem that stereoscopic effect is not real, due to the stereo virtual image position changed along with the moving head position of the user.
