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

摘要

A material defect detection device, a material defect detection system, a material defect detection method, and a program which can easily estimate shape information of a material defect are provided. A material defect detection device for detecting material defect in a predetermined region of a metallic equipment using a magnetic field distribution in the predetermined region measured by a magnetic sensor array, the material defect detection device being provided with a magnetic dipole density distribution calculator for calculating a density distribution of magnetic dipoles in the predetermined region based on the magnetic field distribution measured by the magnetic sensor array, and a depth distribution calculator for calculating a depth distribution of material defect in the predetermined region based on the density distribution of the magnetic dipoles.
