Display Position Correction for Image and Vibration Misalignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display systems face positional deviations of display content due to the combination of vibration correction and image correction processing, where image correction errors occur when vibration correction is performed after image correction, leading to delayed attitude changes and positional deviations of the display content.
Innovation Solution
The display system performs vibration correction processing after image correction processing, calculating the vibration correction amount based on the attitude change amount and image correction error to correct display deviations caused by attitude variations of the moving body, thereby controlling the display position accurately.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If vibration correction processing is performed after image correction processing, then display position accuracy is improved, but image correction errors occur due to delayed attitude changes
Solution Approach 1:
The system performs image correction processing before vibration correction processing, establishing the display position based on attitude information obtained before vibration occurs. This preliminary action ensures that the display position is accurately set before any vibration-induced deviations occur, preventing image correction errors while maintaining display position accuracy.
Solution Approach 2:
The system obtains attitude information from a sensor, performs image correction based on this information, then acquires vibration information after the image correction. The vibration correction processing uses both the attitude information and the newly acquired vibration information to calculate the final display position, creating a feedback loop that compensates for vibration effects while maintaining correction accuracy.
2Productivity
If image correction is performed based on attitude information obtained before vibration, then processing speed is improved, but positional deviation occurs due to attitude changes during vibration
Solution Approach 1:
The system performs image correction processing before vibration correction processing using attitude information obtained before vibration occurs. This preliminary action establishes the base display position quickly, improving processing speed while the subsequent vibration correction step compensates for any positional deviations caused by attitude changes during vibration.
Solution Approach 2:
The correction process is divided into two independent stages: image correction processing that establishes the display position based on pre-vibration attitude information, and vibration correction processing that adjusts for vibration-induced deviations. This segmentation allows each stage to be optimized independently, maintaining processing speed while ensuring accuracy.

AI summary
A display system is for controlling a display of display content. The display system includes: a processor; and a memory having stored thereon instructions executable by the processor. The instructions include: performing image correction involving a change in a display position of the display content based on image correction data stored in advance; detecting an attitude change amount of a movable body; calculating, after the image correction is performed, a vibration correction amount of the display position of the display content based on the attitude change amount of the movable body and an image correction error of the image correction caused by vibration correction processing of correcting a display deviation caused by an attitude variation of the movable body; and controlling the display position of the display content based on the vibration correction amount.
