Long-Image Display With Index Bars for Structural Deformation Inspection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image display systems for large structures, such as tunnels or bridges, fail to clearly indicate the position of deformations within the structure, leading to confusion for users, and often result in cluttered screen configurations when attempting to overlay panoramic and partial images.
Innovation Solution
An image display device and method that utilize a processor to display a partial image of a long image with a first index bar indicating the capture position, allowing users to recognize the structure's portion through a simple and organized screen configuration, featuring options for enlargement, auxiliary windows, and distinction between displayed and non-displayed portions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If both panoramic image and inspection image are displayed on the same screen with frame overlay, then the user can recognize which portion of the structure the captured image corresponds to, but the screen configuration becomes cluttered
Solution Approach 1:
The display screen is segmented into two separate display regions: a first display region for showing the panoramic image and a second display region for showing the inspection image. This segmentation allows both images to be displayed without overlapping, preventing screen clutter while maintaining position information visibility through the index bar in the first display region.
2Device complexity
If only partial image is displayed without position indication, then the screen configuration remains simple, but the user cannot recognize which portion of the structure the image corresponds to
Solution Approach 1:
An index bar is introduced as an intermediary element in the first display region that indicates the capture position of the inspection image within the panoramic image. This index bar serves as a mediator that conveys position information without requiring direct overlay of the images, thus maintaining screen simplicity while providing necessary position context.
3Loss of information
If the entire long image is displayed, then complete position information is provided, but the deformation details cannot be clearly observed
Solution Approach 1:
The display system is segmented into two functional regions: the first display region shows the panoramic image with index bar for position information, while the second display region shows the enlarged inspection image for detailed deformation observation. This segmentation allows simultaneous achievement of both position context and detailed inspection.
Solution Approach 2:
The solution transitions from a single-dimensional display (either panoramic or inspection image) to a two-dimensional display arrangement with separate regions. The first display region provides the contextual dimension (position information) while the second display region provides the detailed dimension (deformation inspection), allowing both to coexist without interference.

AI summary
Provided is an image display device including a processor, in which the processor is configured to perform control to display, on a display, a display screen having a display region for a partial image that is a portion of a long image, which is obtained by imaging a structure extending in a first direction with an imaging device and in which a long side direction is along the first direction, and a first index bar which extends in the first direction and indicates a first distance range that is at least a portion of a distance range of the structure in the first direction and on which a capture position mark indicating a capture position of the partial image, which is being displayed in the display region, in the structure is displayed.
