ECT database and greedy-search inverse analysis for crack shape recovery arising in eddy current testing
This paper is concerned with a method to recover natural cracks from magnetic images obtained by ECT (eddy current testing). In the proposed method, a database is built to store knowledge base of cracks with different sizes and various measurement parameters. In the proposed inverse analysis, Greedy search algorithm invokes knowledge from pre-built database to reconstruct multiple cracks from ECT signals. For the purpose of computational saving in searching process, a parallel distributed computation system is designed. In this master-slave system, workloads of searching process are contributed to slaves for computation and the results are gathered, compared and displayed in a graphics user interface.
