摘要：
We propose a method for reconstructing 2D surface cracks in electrically conducting parts from Eddy-current images. The proposed method relies on the use of a direct semi-analytic model suitable for Eddy-current systems featuring a uniform current excitation. The surface crack reconstruction approach is based on the comparison of eddy current images computed by the model with the eddy current image of the crack to reconstruct. The method is implemented by means of a genetic algorithm and accurate reconstruction is carried out with synthetic data. © 2016 Lavoisier.
