THICKNESS LOSS DETECTION DEVICE, THICKNESS LOSS DETECTION SYSTEM, THICKNESS LOSS DETECTION METHOD, AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide a thickness loss detection device, thickness loss detection system, thickness loss detection method, and program that can readily estimate information on the shape of thickness loss.;SOLUTION: A thickness loss detection device detects thickness loss in a prescribed region by using magnetic field distribution in the prescribed region of metal equipment measured with a magnetic field sensor array. The thickness loss detection device includes: a magnetic dipole density distribution calculation unit for calculating density distribution of a magnetic dipole in the prescribed region on the basis of the magnetic field distribution measured with the magnetic field sensor array; and a thickness loss distribution calculation unit for calculating thickness loss distribution in the prescribed region on the basis of the density distribution of the magnetic dipole.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2018,JPO&INPIT
