A road deterioration determination device includes a selection unit and a determination unit. The selection unit selects an image of a road surface captured at one point on a road on the basis of priorities of values of attributes set for each of points on the road and related to image capture for images of the road surface captured at the points. The determination unit determines road deterioration at the one point using the selected image and a model for determining road deterioration from the image.

Determining deterioration of road by inputting image of the road into a model that has been updated

A deterioration diagnosis device according to the present invention includes: a memory; and at least one processor coupled to the memory. The processor performs operations. The operations include: storing a history of deterioration degree in a portion to be diagnosed in a structure; calculating a deterioration speed of the portion based on the history; acquiring reference information to be used to calculate an inspection frequency; calculating an inspection frequency for the portion based on the reference information and the deterioration speed; and outputting the calculated frequency.
