Defect Size Estimation of Building’s Exterior Wall Using Thermal Decay Gradient Approach

Typical building inspection using Passive Infrared Thermography involves defect analysis, in which defects appear as abnormal temperature distributions in thermal images (thermograms) due to contrasts in the thermal conductive and emissive properties of air (defect) and intact areas (finishes) [...]
