Realization of 3-D Image of Crack Leakage Magnetic Based on LSS-MNS Optimization

摘要

In this paper, the measurement equation based on the dipole model is erected, in order to realize 3-D crack leakage magnetic imaging. The LSS-MNS optimization is proposed to obtain stable and unique solution, in connection with the improperly posed of the equation, then 3-D crack leakage magnetic image is implemented. Some experimental results obtained by inspecting in the experimental and actual steel are in good agreement with the actual one.
