Uma ferramenta de segmentação e atribuição de temperaturas para contribuir com análises termográficas

Abstract

In the context of civil construction, monitoring and analyzing the state of repair of concrete structures is extremely important. Non-destructive tests have emerged as efficient solutions for assessing the quality of constructions, both new and old. Among these tests is infrared thermography, as an agile and versatile technique based on the indirect analysis of the temperature of a building’s structure and façade materials to identify possible pathologies. However, there is a shortage of ready-made tools for analyzing thermographic images, which implies challenges in interpreting the results. Given this scenario, this study proposes the development of a thermographic image segmentation tool. This tool allows the user to define specific colors for image segmentation, visualizing the areas of interest in ranges of values in the RGB and HSV color spaces. In addition, the tool generates a file that records the segmented colors of the aforementioned spaces, along with the maximum and minimum temperatures providing a visualization of the colors and their respective temperatures.
