Abstract :
This paper describes fuzzy damage extraction method for ultrasonic nondestructive testing images. In our experiment, we employ a piece of wind turbine blade as a specimen has artificial damages. We acquire ultrasonic waveforms from scanning lines on surface of the pecimen using an ultrasonic single probe. To extract the damages, we calculate fuzzy degrees of average difference data of all scanning lines, and make fuzzy images whose ntensities calculated by the fuzzy degrees. As the results, we found the line image with all damage portions, and we estimated depth of damage surface with high accuracy.
