Název v původním jazyce

Quantitative evaluation of active thermography using contrast to noise ratio

Popis výsledku v původním jazyce

Active thermography is an infrared based technique for material non-destructive testing. It often uses advanced evaluation techniques based on temperature spatial and temporal changes. Results of the active thermography are contrast differences, which indicate possible defects in an inspected material. These differences cannot be quantified by temperature. This contribution is focused on active thermography results evaluation parameters and contrast to noise ratio (CNR) method, which can be used for quantitative evaluation of the results. Different results interpretation procedures are introduced. An influence of selection method for indication and reference regions and an effect of image scaling on inspection results are discussed.
