摘要

A determination assist system including a first image generating section for generating a first planar image based on data of a first test index; a second image generating section for generating a second planar image based on data of a second test index; a differentiation section which differentiates the first planar image and the second planar image to generate a first differential image and a second differential image, respectively; a binarization section which binarizes the first differential image to generate a first binary image including a first region which is not less than a first threshold and a second region which is less than the first threshold, and binarizes the second differential image to generate a second binary image including a third region which is not less than a second threshold and a fourth region which is less than the second threshold; and a determination image generating section.

1. A determination assist system for use in ultrasonic testing, which generates a determination image used to determine whether or not a composite material component is healthy, based on data of plural kinds of test indices obtained in an ultrasonic testing device, the determination assist system comprising:
a first image generating section for generating a first planar image which is a gradational image, based on data of a signal intensity of a reflected sound wave as a first test index; a second image generating section for generating a second planar image which is a gradational image, based on data of a propagation time of an ultrasonic sound wave as a second test index; a differentiation section which differentiates the first planar image to generate a first differential image which is expressed as different tones corresponding to differential values, respectively, and differentiates the second planar image to generate a second differential image which is expressed as different tones corresponding to differential values, respectively; a binarization section which binarizes the first differential image to generate a first binary image including a first region which is not less than a first threshold and a second region which is less than the first threshold, and binarizes the second differential image to generate a second binary image including a third region which is not less than a second threshold and a fourth region which is less than the second threshold; and a determination image generating section which generates the determination image based on the first binary image and the second binary image, wherein the determination image generating section generates the determination image by superposing the first binary image and the second binary image in such a manner that a fifth region where the first region and the third region overlap, a sixth region where the first region and the fourth region overlap, a seventh region where the second region and the third region overlap, and an eighth region where the second region and the fourth region overlap can be distinguished from each other.
