摘要

To provide a structure maintenance supporting system that can accurately and quickly associate any position on a structure with a position in the drawing of the structure that is referred to at the time of maintenance. A maintenance supporting system includes an image displaying device that displays an image of a structure to be referred to when any damaged position on the structure is maintained, and a processing unit that performs calculation to associate the damaged position with a position in the image. The processing unit includes a damaged position calculating section that calculates a target coordinate which is the coordinate of the damaged position using known coordinates given to a plurality of reference points, and a position specifying section that specifies a position in the image corresponding to the target coordinate with an indication on the image displaying device.
