A Method for Generating and Evaluating Magnetic Flux Leakage Data for Large-diameter Pipeline Crack Defects Based on Numerical Simulation and Diffusion Algorithm

Considering that the sample size of magnetic flux leakage （MFL） data for large-diameter pipeline crack defects is insufficient to support the quantitative identification， a database generation method integrating numerical simulation of MFL field and diffusion algorithm was proposed， and it was verif...
