Structure evaluation system, structure evaluation apparatus, and structure evaluation method

A structure evaluation system comprising:

• a plurality of sensors configured to detect elastic waves generated from a structure;
• a position locator configured to locate a position of a generation sources of a plurality of elastic waves on the basis of the plurality of elastic waves detected by the plurality of sensors;
• and
• an evaluator configured to evaluate a deterioration state of an area of which a frequency at which an impact is applied is assumed to be equal to or higher than a threshold in an evaluation target area on the basis of a position locating result acquired by the position locator.

A structure evaluation apparatus comprising:

• a position locator configured to locate a position of a generation sources of a plurality of elastic waves on the basis of the plurality of elastic waves detected by a plurality of sensors detecting elastic waves generated from a structure;
• a corrector configured to correct information based on the position locating performed by the position locator using a correction value set in correspondence with an impact;
• and
• an evaluator configured to evaluate a deterioration state of the structure on the basis of the corrected information.

A structure evaluation method comprising:

• locating a position of a generation sources of a plurality of elastic waves on the basis of the plurality of elastic waves detected by a plurality of sensors detecting elastic waves generated from a structure;
• correcting information based on the position locating using a correction value set in correspondence with an impact;
• and
• evaluating a deterioration state of the structure on the basis of the corrected information.
