ABSTRACT
Infrared thermography is a technique based on the acquisition of the thermal radiation of the bodies using thermographic cameras, which produce an image of the radiation captured through the conversion of radiation values to temperature values. This translation requires the knowledge of certain parameters such as emissivity value of the surface of the body under study, ambient conditions (temperature and relative humidity), and distance to the body. Once the temperature values are known, different studies can be made based either on the absolute temperature values, on the relative temperatures between the different parts of the bodies, or between the different bodies appearing in the images. Medicine, veterinary, electrical and mechanical inspections, building energy efficiency and condition of civil infrastructure, are among the most common applications of the technique.
