An Object Temperature Estimation Based on Obtained Infrared Thermal Images

There is a continuous increase in the applications for Infrared (IR) thermal imaging, it is applied in research and development and in different fields of science and industry; such as analyzing building insulation, heating pipes, electrical components, or reducing energy costs of the buildings, etc. This paper focuses on determining a temperature of an infrared thermal image for buildings, based on emissivity change of the building substances and the heat flux. In this paper, temperature estimation method has performed for specified part (white rectangular) on the thermal images for three selected different buildings captured by infrared camera. Infrared camera FLIR T420, and FLIR Tools software package has used for the estimating and analyzing the temperature for the specified region in the images. The obtained results by IR camera demonstrate that the estimated temperatures are affected by changing the emissivity of the objects.
