    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: A displacement measurement device includes: a first machine learning model trained to generate, from one image which contains a subject and has noise, at least one image which contains the subject and which has noise or has had noise removed; a first obtainer that obtains a first image which contains the subject and has noise and a second image which contains the subject and has noise; a first generator that, using the first machine learning model, generates M template images containing the subject from the first image and generates M target images containing the subject 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 information presentation method according to the present disclosure includes: acquiring two or more monochrome images obtained by image-capturing a structure using a monochrome camera and one or more first color images obtained by image-capturing the structure using a color camera, the one or more first color images having a less amount of information than an amount of information of the two or more monochrome images; detecting a displacement that indicates a movement of the structure based on the two or more monochrome images; generating presentation information that includes one or more second color images that present information that indicates the displacement based on the two or more monochrome images and the one or more first color images; and outputting the presentation information.
