Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In MR technologies, aligning image data with structures in a construction environment is challenging due to deviations that occur when a user moves, requiring labor-intensive marker placement to maintain position alignment.
Innovation Solution
An image display device with a storage unit for design data, a display unit for composing images, and a correction unit that adjusts deviations using coordinates correction positions based on user position and design data to align image data with structures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If markers are disposed corresponding to positions throughout the structure to maintain position alignment, then position alignment accuracy is improved, but device complexity and labor requirements increase
Solution Approach 1:
The patent extracts the position alignment function from multiple markers and concentrates it into a single marker. The correction unit calculates deviation based on one marker's position and applies correction to the entire composite image, eliminating the need for multiple markers while maintaining alignment accuracy.
Solution Approach 2:
The single marker serves multiple functions: it provides position reference, enables deviation calculation, and supports correction for the entire composite image. The correction unit uses this single marker to perform universal position alignment correction across all composite elements, replacing the need for position-specific markers.
2Reliability
If markers are disposed throughout the structure to correct position alignment deviation, then position alignment reliability is improved, but ease of operation deteriorates due to labor-intensive marker setting
Solution Approach 1:
The patent extracts the position reference function from multiple markers and concentrates it into a single marker. The correction unit calculates the composite image's deviation from the structure based on this one marker and applies correction, eliminating time-consuming multiple marker disposal while maintaining alignment reliability.
Solution Approach 2:
The system performs self-correction by automatically calculating deviation and adjusting composite image positions based on the single marker data. The correction unit autonomously computes position offsets and applies corrections without requiring manual intervention for multiple marker placements, improving operational ease.

AI summary
An object is to provide an image display device capable of correcting a position in a simple manner even when a deviation occurs in position alignment in accordance with movement of a user. The image display device 100 includes a correction processing unit 102 that corrects a deviation when the deviation occurs between image data G and a steel frame T in a field of vision of a user U that occurs in accordance with movement of the user. This correction processing unit 102 acquires a coordinates correction position S that becomes a reference position used for a correction process from the steel frame T1 or the like that is a partial member using design data stored by a storage unit 103 and a self-position of the user U with respect to the steel frame T. The correction processing unit 102 performs correction by performing position alignment of the image data G on the basis of the one coordinates correction position S.
