Abstract: The present invention relates to a quantitative modeling method to evaluate drafting and extents of damage in delamination zones of stone cultural heritage, comprising: securing thermographic images by a manual method using temperature difference in a natural condition and by an active method using an infrared halogen heater after preceding with visual observation and picture taking of delaminated specimens, preparing a temperature distribution curve on the thermographic images obtained by the active method to set threshold temperatures and interface zones of delamination zones, conducting monochromatic processing after classifying relative damage classes through temperatures and temperature changes of the delamination zones, and conducting evaluation of damage extents through drafting and area calculation of the delamination zones through a stage of extracting the monochromatic images with vector lines. Said method is very useful for displaying the positions, the areas and the relative extents of damage of delamination zones as drawings that cannot be visually affirmed, while relating to a method to enhance the reliability of an evaluation for extents of damage in stone cultural heritage. [Reference numerals] (S100) Check delaminated specimens with human eyes, take pictures of them, and obtain passive thermographic images of them;(S200) Obtain active thermographic images of the delaminated specimens using an infrared halogen heater;(S300) Make a temperature distribution curve based on the active thermographic images;(S400) Set threshold temperatures and interface zones of delamination zones using the temperature distribution curve;(S500) Classify relative damage classes based on temperatures and temperature changes of the delamination zones;(S600) Conduct a monochromatic process according to the relative damage classes of the delamination zones;(S700) Convert the monochromatic images into vector lines thereby extracting the vector lines;(S800) Evaluate damage extents through drafting and area calculation of the delamination zones
