Construction Deformation Matching for Secular Change Assessment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing infrastructure inspection methods struggle to efficiently determine the state of secular change in construction deformations due to misalignment issues in images captured at different time periods, particularly in constructions with numerous deformations, requiring extensive processing time to establish corresponding relationships.
Innovation Solution
An information processing apparatus that selects key deformations based on attributes and relative positional relationships, calculates matching degrees, and determines reference deformations to efficiently assess the state of secular change by focusing on important deformations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If all deformations are processed to obtain corresponding relationships between images captured at different time periods, then the accuracy of secular change determination is improved, but the processing time increases significantly
Solution Approach 1:
The patent segments the set of all deformations into two categories: important deformations (selected based on shape, size, position, or user specification) and non-important deformations. Only important deformations are processed to establish corresponding relationships between images, while non-important deformations are excluded from this processing step. This segmentation maintains measurement precision for critical deformations while significantly reducing processing time by avoiding unnecessary computation on less significant deformations.
Solution Approach 2:
The patent extracts and selects only the important deformations from the complete set of detected deformations based on predetermined criteria (shape characteristics, size thresholds, positional information, or user selection). By taking out only the essential deformations that contribute meaningfully to soundness determination, the system achieves accurate secular change measurement without the computational burden of processing all deformations equally.
2Reliability
If image processing is performed on all deformations to account for misalignment, then the reliability of deformation correspondence is improved, but the productivity of the inspection system deteriorates
Solution Approach 1:
The patent divides deformations into important and non-important groups, applying full image processing and misalignment correction only to important deformations. This selective approach ensures reliable correspondence determination for critical deformations while maintaining high inspection efficiency by skipping processing for non-important deformations.
Solution Approach 2:
Instead of performing complete image processing on all deformations, the patent applies partial action by processing only the subset of important deformations. This partial processing approach provides sufficient reliability for soundness determination without the excessive computational cost of processing every detected deformation.

AI summary
This invention provides a processing apparatus for determining a state of secular change of a deformation of a construction, comprising a selection unit that selects, as a target for determination of secular change, at least a portion of deformations from among a plurality of deformations included in a first image at a first time period, on the basis of at least one of information relating to deformations, information relating to the construction, user selection, or a shape and a relative positional relationship of two or more deformations; a first determination unit that determines a deformation corresponding to a selected deformation among a plurality of deformations included in a second image at a second time period; and a second determination unit that determines a state of secular change between a selected deformation and a deformation determined by the first determination unit.
