Claim 0:
1. A structure management device comprising:
at least one processor configured to:
acquire an image group in which a structure is imaged with overlap areas by a camera by moving a moving object equipped with the camera;
analyze images in the image group to detect damage of the structure;
acquire three-dimensional design data indicating the structure;
track point group data of feature points common in the overlap area between the images in the image group to calculate combined information including a camera position and a camera posture in a case of capturing the image by the camera and a three-dimensional position of the point group data; and
map the detected damage on a surface of the structure indicated by the acquired three-dimensional design data based on the combined information based on a correction coefficient and by using the combined information, wherein the correction coefficient is calculated such that the surface of the structure indicated by the acquired three-dimensional design data coincides with a surface corresponding to the three-dimensional position of point group data.
