To suitably determine a measurement cycle at which to measure cracks that occur in structures formed from concrete or the like. Resolution Means: A measurement cycle determination device () includes a related information acquisition unit () that acquires at least one of geographic information including items related to a geography of a site where a structure is located, weather information including items related to weather at the site, and structure information including items related to the structure; a crack information acquisition unit () that acquires crack information related to a crack that has occurred in the structure; a measurement cycle determination unit () that determines, on the basis of at least one of the geographic information, the weather information, the structure information, and the crack information, a measurement cycle at which to measure a width of the crack; and a measurement cycle output unit () that outputs a measurement cycle signal indicating measurement cycle information related to the determined measurement cycle.

Problem: To extract an image including a desired area included in a moire area from an image in which a sheet that includes the moire area has been imaged. An image area extracting deviceextracts an image area from an image in which a sheet has been imaged provided with a first layer section having a first pattern including a plurality of drawn lines extending in a first direction, a second layer section overlapping the first layer section and including a plurality of drawn lines extending in a second direction that is different from the first direction, and a low adhesion section where adhesive force is lower than that of an adhesive section and an adhesion section arranged on an adhesive surface opposite a surface facing the first layer section and the second layer section. At this time, the image area extracting deviceexecutes processing that includes acquiring sheet image data showing a sheet image including a sheet imaged so as to include a moire area where a moire is created by overlaying the first pattern and the second pattern is acquired, extracting the moire area from the sheet image, extracting a non-fixing area where the low adhesion section is arranged based on a size of a fixing area where the adhesion section is arranged, and outputting non-fixing area image data showing a non-fixing area image including the non-fixing area.

Problem: To provide a sheet that can clearly and easily measure displacement when displacement of a subject is small, and to provide an article for evaluating the deformation of a building containing this sheet. Resolution Means: A sheet having a first main surface and a second main surface facing the first main surface, including a first section having a first pattern image, a second section having a second pattern image, and the third section provided between the first section and the second section, wherein the first section has higher extensibility then the second section, the first section includes a first main surface of the sheet, the second section includes a second main surface of the sheet, the first pattern image is visible through the second pattern image, and the first main surface includes a high adhesive surface and a low adhesive surface.
