Claim 8:
9. A structure management method comprising:
a step of acquiring, by at least one processor, an image group in which a structure is imaged with overlap areas by a camera by moving a moving object equipped with the camera;
a step of analyzing, by the at least one processor, images in the image group to detect damage of the structure;
a step of acquiring, by the at least one processor, three-dimensional design data indicating the structure;
a step of tracking, by the at least one processor, 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
a step of mapping, by the at least one processor, the detected damage on a surface of the structure indicated by the acquired three-dimensional design data, based on the calculated 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.
