Abstract
A structure displacement amount measurement apparatus includes: an acquiring unit configured to acquire a displacement amount caused on a structure by a weight of a vehicle traveling on the structure along a time series; an estimating unit configured to estimate a section in which displacement is caused based on time-series data of the displacement amount; a detecting unit configured to detect a feature value of change in displacement amount within the estimated section; a determining unit configured to determine whether or not the estimated section is a section of displacement due to a weight of a single vehicle based on the detected feature value; and an extracting unit configured to extract a displacement amount from the time-series data within a section of displacement due to a weight of a single vehicle based on a result of the determination.
