Disaster Image Collation for Rapid Situation Specification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for quickly ascertaining and specifying disaster situations are hindered by the need for on-site investigations and the limitations of available global information, which often lack detailed damage assessments.
Innovation Solution
An information display apparatus and method that collate overhead images taken before a disaster with target images showing the disaster situation, using criteria to determine minimal disaster influence, to specify the position of objects and display relevant information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a large number of disaster site images are provided to enable detailed damage assessment, then the completeness of damage information is improved, but the time required to select and organize useful images increases
Solution Approach 1:
The patent segments the image selection process by pre-classifying images into categories (buildings, vehicles, roads, etc.) before a disaster occurs. This segmentation allows rapid filtering and selection of relevant images during the emergency response phase without manually reviewing all available images, thus reducing time loss while maintaining information completeness.
Solution Approach 2:
The system performs preliminary actions by collecting, classifying, and organizing disaster site images into structured categories before the actual disaster occurs. This pre-preparation enables immediate utilization of organized image data during emergency response, eliminating the need for time-consuming on-site image selection and organization.
2Ease of operation
If image classification into predefined classes is used to organize images, then the ease of image organization is improved, but the ability to quickly specify and ascertain disaster situations deteriorates
Solution Approach 1:
The patent adds a spatial dimension to image classification by associating classified images with their geographical locations and creating a composite view that integrates both classification data and spatial information. This dimensional enhancement allows users to quickly locate and specify disaster situations by combining categorical organization with positional data, thus improving productivity while maintaining ease of operation.
Solution Approach 2:
The system introduces an intermediary layer that combines image classification results with geographical location data and disaster situation information. This intermediary composite structure enables rapid specification of disaster situations by mediating between the organized classification data and the need for quick situational awareness, resolving the contradiction between organization ease and specification speed.

AI summary
An information display apparatus includes: a collation unit that specifies a position of an object in an overhead image obtained by capturing an image of a region that includes the object before a disaster, based on a result of collating the overhead image with a section in a target image that includes a situation of the object after the disaster, the section satisfying a criterion for determining that an influence of the disaster is small; and a display unit that displays an image that includes the situation of the object and information by which the position of the object in the overhead image can be specified.
