Infrared Non- Destructive Testing Using Image Processing: A Survey

Abstract: Non-destructive Testing (NDT) is a wide clump of analysis techniques. These techniques are used in industries and sciences to calculate and guesstimate the properties of material, substance or a system without damaging it. NDT is highly valuable technique as it does not enduringly change the substance being scrutinized and hence can save the money and time in product evaluation, troubleshooting and research. Infrared and Thermal testing is one of the many Non-destructive Testing techniques provided by the American Society for Non-destructive Testing (ASNT). This paper has concentrated the study towards Infrared Thermography which is the science of measuring and mapping surface temperature. It has proven to be an effective, expedient, and economical method of testing.
