3D Construction Image Display for Spatial Photo Mapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image management systems fail to help users easily identify the portion of a construction corresponding to a selected captured image, especially when image capture areas are small relative to the construction, leading to confusion in image comparison.
Innovation Solution
An image display apparatus and method that superimposes a mark on a three-dimensional model indicating the position of a selected captured image, accompanied by a list of images that can be filtered and sorted based on user-defined conditions, allowing easy identification of the corresponding construction portion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the system displays only target images of inspection target parts, then the user can view captured images of specific segments at once, but the user cannot grasp which portion of the construction corresponds to a selected captured image when image capture areas are small
Solution Approach 1:
The patent adds a spatial dimension by superimposing a mark on the three-dimensional model at the location corresponding to the selected captured image. This visual marker in the three-dimensional space establishes a direct spatial correspondence between the two-dimensional image and the three-dimensional construction, resolving the information loss about which portion the image represents.
Solution Approach 2:
The patent introduces a three-dimensional model as an intermediary between the captured images and the construction. The mark superimposed on the three-dimensional model acts as a mediator that links the selected image to its corresponding spatial location on the construction, enabling users to understand the relationship without directly comparing small images with the entire construction.
2Ease of operation
If the system presents target images extracted from captured images, then the user can obtain images of inspection target parts, but the user cannot easily identify the corresponding construction portion when there are many similar captured images
Solution Approach 1:
The patent uses visual markers (marks) superimposed on the three-dimensional model to highlight the spatial location corresponding to the selected captured image. This visual indication helps users quickly identify which construction portion the image represents, making it easier to detect and measure the image-construction correspondence even among many similar images.
3Loss of information
If the system displays a three-dimensional model with a mark indicating the selected image position, then the user can grasp the corresponding construction portion, but the system complexity increases
Solution Approach 1:
The patent uses a simplified visual marker (such as a point, line, or symbol) superimposed on the three-dimensional model to represent the spatial correspondence relationship. This simple copy or symbol conveys the complex spatial information efficiently, adding minimal visual complexity while providing complete spatial correspondence information between the selected image and the construction.

AI summary
There are provided an image display apparatus, an image display method, and an image display program with which in a case where a user selects any captured image from a group of captured images obtained by image capturing of a photographic subject, such as a construction, the user can easily grasp a portion of the photographic subject corresponding to the selected captured image. An image list indicating a group of captured images obtained by image capturing of a photographic subject from different image capture positions and in different image capture directions relative to the photographic subject is displayed on a display unit, and an instruction for selecting any captured image from the image list is accepted in accordance with a user operation. A three-dimensional model of the photographic subject is displayed on the display unit, and a mark indicating the position of the captured image for which the instruction for selection has been given is superimposed and displayed on the displayed three-dimensional model. Accordingly, the user can easily grasp a portion of the photographic subject (three-dimensional model) corresponding to the selected captured image.
