Abstract: An information processing device 1 includes a feature detection unit 28 for detecting, from a construction image acquired by an imaging device by capturing an image of a construction that includes a plurality of unit structures respectively having identical or similar external structures, a feature relating to the external structures, and a unit structure estimation unit 29 for estimating parts of the construction image that correspond respectively to the plurality of unit structures included in the construction on the basis of a plurality of the detected features.

Abstract: An information processing device 1 includes a motion acquisition unit 22 for acquiring a motion magnitude for each of a plurality of image elements included in a plurality of captured images, a threshold determination unit 23 for determining a threshold used to exclude image elements not to be included in a histogram showing a distribution of the motion magnitudes of the image elements, a histogram creation unit 24 for creating the histogram with respect to image elements, among the plurality of image elements, excluding image elements having motion magnitudes that exceed the threshold, a range estimation unit 25 for referring to the histogram in order to estimate a motion magnitude range corresponding to image elements capturing a predetermined part of the imaging subject, the predetermined part being within a predetermined distance range of an imaging position, and an image element specification unit 26 for specifying the image elements capturing the predetermined part by specifying the image elements belon

Abstract: An information processing device 1 includes: a feature area detection unit 28 that acquires, by inputting a target image showing a fastening part that is an inspected target to a machine learning model, a feature area based on an estimated coordinate that includes a feature point relating to reference indication added to the fastening part and relates to a position of the feature point and a distribution of the estimated coordinate; an uncertainty evaluation unit 29 that determines whether the feature area satisfies a prescribed reference; and a fastening state determination unit 30 that determines a fastening state of the fastening part based on the estimated coordinate when the feature area satisfies the prescribed reference.
