ABSTRACT

Thermal imaging is contemporary remote sensing measurement technique, which provides an image of the temperature distribution in the measured object. The method is widely used, due to its mobility as well as the non-destructive character of the measurement. Infrared thermography is especially relevant in the inspection of insulation, what is more, it is a suitable device for detecting thermal bridges and structural changes, which can impact building energy performance. In the paper, authors brought up the issue and described the basics of infrared tomography briefly. The primary goal of the study is to test the solution on a practical example. The authors carried out measurements using a thermal imaging camera on a residential building in Gdynia. The analysis and processing of collected material for investigation of surface deterioration were made. In addition, a comparative qualitative analysis of image processing filters was made to determine if such filters can improve the visibility of building surface damage.

Keywords: building investigation, image processing, masonry structures, remote sensing, thermal imaging.
