Sizing of 3-D Arbitrary Defects Using Magnetic Flux Leakage Measurements
Abstract
In this paper, we propose a new procedure to estimate the shape of the opening and the depth profile of an arbitrary three-dimensional (3-D) defect from magnetic flux leakage (MFL) measurements. We first use the Canny edge detection algorithm to estimate the shape of the defect opening. Then we use an inversion procedure based on the space mapping (SM) methodology in order to approximate the defect depth profile efficiently. To demonstrate the …
