Abstract: A structure investigation assistance system comprises: a first storage unit that stores image data of a road captured continuously by a camera; a second storage unit that stores detailed information about a structure around the road in association with position information about the structure on a map, the detailed information on the structure being configured using point cloud data obtained by 3D scanning the structure; a first selection unit that selects, from the first storage unit, image data targeted for an investigation request in a case where a request for an investigation of the structure is received; a second selection unit that selects, from the second storage unit, detailed information about the structure targeted for the investigation request; and an information presentation unit that presents a map indicating a location of the structure, the image data selected, and the detailed information about the structure.
