Abstract: A displacement output device according to the present invention includes: a memory; and at least one processor coupled to the memory. The processor performing operations. The operations include: acquiring a first ground surface displacement at a first point from a synthetic aperture radar; estimating a second ground surface displacement at a second point different from the first point using the acquired first ground surface displacement; clipping at least one of the first ground surface displacement and the second ground surface displacement included in a preset first region from the first ground surface displacement and the second ground surface displacement; and outputting at least one of the first ground surface displacement and the second ground surface displacement included in the first region.

Abstract: A deterioration assessment device includes: a memory; and at least one processor coupled to the memory. The processor performs operations. The operations include: acquiring information on displacement of a ground surface; extracting a position at which sensor information used for assessment of deterioration is acquired based on the information on the displacement of the ground surface; and outputting the extracted position.

Abstract: A deterioration prediction system according to an aspect of the present disclosure includes: at least one memory configured to store instructions; and at least one processor configured to execute the instructions to: predict a deterioration level of the road at prediction time points according to road inspection data and the prediction time points, the road inspection data obtained by inspecting a road and the prediction time points indicating future time points, and superimpose the deterioration level on a map for each of the prediction time points in a display mode according to the deterioration level.
