This paper proposes a novel method for visualizing the multiple cracks from ECT image. Assumed two-dimensional scanned ECT signals to be a picture image, then a template matching method predicts crack shapes. Moreover, comparing ECT image of the unknown multiple cracks and that of the known crack separates into each of the cracks. Genetic algorithm performs faster search algorithm in our template matching. Shape reconstructions are achieved in the multiple cracks at intervals of 2 mm with a satisfactory degree of accuracy.
