초록
This study aims to detect defects using infrared thermography, measuring their size accurately for diagnosis and maintenance. It utilizes infrared thermal images for detection and applies the Gauss function to temperature distribution for quantitative evaluation, considering camera specifications such as Instantaneous Field of View (IFOV). The test object had both external and internal defects. The accuracy in evaluating external defects was within a 7.5% error rate regardless of depth, and for internal defects, except those 30-40mm deep, the error rate stayed below 8.6%.
