PORE POSITION ACQUISITION METHOD OF CONSTRUCTION OBJECT, AND HEAT INSULATION COATING METHOD USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a pore position acquisition method of a construction object for exactly acquiring a position of a pore provided on the construction object.SOLUTION: A pore position acquisition method of a construction object comprises: an acquisition step S21 of acquiring a surface shape of the construction object by scanning a surface of the construction object on the surface of which a pore is formed with a laser beam; a calculation step S22 of calculating a center position of the pore from a reference position of the construction object on the basis of the acquired surface shape; an imaging step S23 of guiding an imaging part so that an optical axis of the imaging part matches to the center position, and picking up an image of the pore by the imaging part; and a correction step S24 of correcting the center position of the pore on the basis of the image of the pore.
