Hammering test system

A hammering test system comprising:

• a hammering test device including a target, a flying unit, a hammering test mechanism configured to conduct a hammering test on a test object, and a sound pickup unit;
• a surveying instrument including a scanner for acquiring point cloud data by scanning with scanning light, and configured to be capable of performing tracking and distance and angle measurements of the target;
• and
• an arithmetic processing unit including a point cloud data analyzing unit configured to calculate shape data by analyzing point cloud data acquired by the scanner, and a flight plan calculating unit configured to calculate a flight plan of the hammering test device based on the shape data calculated by the point cloud data analyzing unit,
• wherein the surveying instrument tracks the target of the hammering test device and makes distance and angle measurements at a timing synchronized with a timing of conducting a hammering test by the hammering test mechanism,
• wherein the flight plan calculating unit sets test points to be subjected to a hammering test at intervals of a predetermined distance on a surface of the shape data, and calculates a flight plan in which a hammering test is conducted thoroughly on a surface of the test object,
• wherein detection of an abnormal sound by the sound pickup unit in response to the hammering test on the test object is always interpreted as a detection of structural abnormality in the test object, and
• wherein the flight plan calculating unit is further configured to change the flight plan upon detection of the structural abnormality in the test object.
