Recently, infrared thermography that analyzes a blistering zone from surface temperature is widely used in stone cultural heritages. This study focused on quick detection and quantitative modeling of blistering zones. Blistering modeling for the stone cultural heritages should be carried out as following orders; aquisition of thermography image, establishment of critical temperature, monochromatic processing, extraction of vector line, mapping of blistering zone, and calculation of deterioration rate. The deterioration rate of blistering zones of Cheomseongdae observatory and Sungnyemun stone block foundation using the infrared thermography were 1.5% and 6.6%, respectively.
