A state determination device according to the present invention includes: a memory; and at least one processor coupled to the memory. The processor performs operations. The operations including: combining output from a plurality of determination models for an input image of a road, the plurality of determination models each learned using training data in which at least one of a state of a moving object mounting an imaging device that acquires an image of the road, a state of the road, and an external environment is different.

State determination device, state determination method and recording medium

A deterioration diagnosis device according to an example aspect of the present invention includes: a memory; and at least one processor coupled to the memory. The processor performs operations. The operations include: acquiring an image including a portion to be diagnosed in a structure; calculating, by using the image, deterioration degree that is a degree of deterioration of the portion; calculating reliability for the deterioration degree based on imaging information that is information related to capturing of the image; and outputting the deterioration degree and the reliability in association with each other.

Deterioration diagnosis device, deterioration diagnosis method, and recording medium

A road deterioration diagnosing device acquires an image capturing a road and a date and a time when the image was captured as well as a location and a direction in which the image was captured, detects deterioration of the road surface shown in the acquired image, calculates a direction in which a shadow of a building may be formed over the road surface shown in the image using the date, the time, the location, and the direction, and determines a possibility of erroneous detection of the deterioration on the basis of the direction in which the road surface deteriorates and the direction in which the shadow may be formed.

Road deterioration diagnosing device, road deterioration diagnosing method, and recording medium

A degradation display 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 perform: acquiring a degradation index indicating a degradation state of a road section, changing display form of a map in accordance with a display range and a scale of the map, and superimposing degradation information on the map, the degradation information based on the degradation index of an area on the map or the road section in the area, wherein the superimposing includes: superimposing, for each area, the degradation information in a display form corresponding to a degree of the degradation index of the area in a case that the map is at a first scale, and superimposing, for each road section, the degradation information in a display form corresponding to a degree of the degradation index of the road section in a case that the map is at a second scale larger than the first scale.
