Solution Overview
Problem
Existing soundness evaluation methods for constructions, such as bridges, suffer from reduced accuracy when measurement points belonging to different segments with varying displacement characteristics are included in a single evaluation, leading to deteriorated evaluation accuracy.
Innovation Solution
An information processing apparatus that segments measurement points for each segment of a construction based on three-dimensional position information, selects displacement information within a preset period and range, calculates a correlation index value using environmental data, and generates a determination condition for evaluating soundness based on these values.

Engineering Contradiction Analysis
1Area of stationary object
If measurement points from different segments are included in a single evaluation range, then the evaluation covers more areas of the construction, but the accuracy of the soundness evaluation deteriorates
Solution Approach 1:
The patent divides the construction into multiple segments based on displacement characteristics, with each segment containing measurement points that exhibit similar displacement behavior. By evaluating each segment separately rather than treating all measurement points as a single group, the system maintains high evaluation accuracy while still covering the entire construction area. This segmentation allows the determination condition to be applied uniformly within each segment without being degraded by heterogeneous displacement patterns from different construction portions.
2Ease of operation
If a single determination condition is used for all measurement points, then the evaluation process is simpler, but the accuracy of soundness evaluation for segments with different displacement characteristics deteriorates
Solution Approach 1:
The patent segments measurement points into multiple groups based on their displacement characteristics, allowing different evaluation approaches for different segments while maintaining overall process simplicity.
Solution Approach 2:
The patent applies the same determination condition uniformly within each segment, ensuring that the evaluation process remains simple and consistent for each local group. This local uniformity allows segments with different displacement characteristics to be evaluated appropriately without requiring complex different determination conditions for each segment.

AI summary
An information processing apparatus segments a plurality of measurement points for each segment of a construction in a two-dimensional image based on three-dimensional position information of the plurality of measurement points included in the construction. The apparatus selects a plurality of pieces of displacement information including displacement amounts of the plurality of measurement points included in a preset period and a set range for the construction. The apparatus calculates a correlation index value representing a correlation for at least one of the segments included in the set range based on the selected displacement information and environment information indicating a state of an environment around the set range. The apparatus generates a determination condition for evaluating soundness of the construction for the at least one segment based on the correlation index value of the at least one segment.
