Abstract: An information processing method includes: obtaining training images generated by a camera shooting a target point and training parameters related to a position/orientation of the camera when shooting the training images; generating, using the training parameters as inputs, a model that outputs a first displacement amount by which a target block corresponding to the target point displaces from a reference position in the training images; obtaining measurement images generated by the camera shooting the target point and measurement parameters related to the position/orientation of the camera when shooting the measurement images; obtaining a second displacement amount, output by inputting the measurement parameters into the model, by which a target block corresponding to the target point appearing in the measurement images displaces from a reference position in the measurement images; and outputting a displacement obtained by subtracting the second displacement amount from displacement of the target block in the measurement images.

Abstract: An imaging parameter output method is a method of outputting an imaging parameter of an imaging device that captures an image for measuring a displacement representing a movement of an object. The imaging parameter output method includes: obtaining object information identifying the object, and a geometric imaging condition for imaging the object; calculating the imaging parameter including a candidate imaging area for placing the imaging device and the accuracy in measuring the displacement in the candidate imaging area, based on the object information and the geometric imaging condition, without imaging the object using the imaging device; and outputting the imaging parameter.

Abstract: A displacement measurement device includes: an obtainer that obtains a first image which contains a subject and a second image which contains the subject; a generator that generates M template images which contain the subject and which have noise from the first image and generates M target images which contain the subject and which have noise from the second image, M being an integer of 2 or higher; a hypothetical displacement calculator that calculates M hypothetical displacements of the subject from the M template images and the M target images; and a displacement calculator that calculates a displacement of the subject by performing statistical processing on the M hypothetical displacements.

Abstract: An observation method includes: displaying video of a subject; receiving designation of at least one point in the video; determining an area or edge in the video based on the point; setting, in the video, observation point candidates in the area or on the edge; evaluating an image of each observation block candidate having a center point that is a corresponding observation point candidate, eliminating any observation point candidates not satisfying conditions, and setting remaining observation point candidates to a plurality of observation points; and observing a movement of the subject itself applied with an certain external load at each observation point. The conditions are that (i) the subject is in a corresponding observation block candidate, (ii) image quality of the observation block candidate is good without temporal deformation or blur, (iii) a displacement of the observation block candidate is not greater than that of any other observation block candidates.

Abstract: An inspection device inspects fastening members that fasten a structure. The inspection device includes an obtainer that obtains images including a first image and a second image of the fastening members at times different from each other; a detector that detects first displacements that are respective displacements of the fastening members based on the first image and the second image; and an identifier that identifies, out of the fastening members based on the first displacements, a target fastening member behaving differently from other fastening members.
