In this study, in order to improve the detection accuracy of defective parts in the wall by infrared thermography, surface color and dirts on the wall are quantified as the color values and spectral absorption obtained from the digital image. Furthermore, correcting method of the infrared thermography image by the surface color value is investigated. According to the results, the thermal difference of surface of wall by inner deffect is in good correlation with the spectral absorption, and it is clarified that it is possible to correct the infrared thermographic image by the analysis with spectral absorption obtained from the digital image.
