| Popis: |
Cracks are structural pathologies that affect the structural integrity of historical buildings. The methodologies commonly used to detect cracks are based on visual inspections or in intrusive techniques that involve removing external wall layers. The main objective of this study is to develop and validate a semi-automatic and non-destructive tool that helps the user to analyze the position and growth of the cracks in masonry constructions based on a photogrammetry analysis. The developed tool uses image processing to plot a curve of the crack area, and, in case needed, its evolution over time. The tool was validated in laboratory using earthen samples that were subjected to uniaxial compression tests. The research also provides the results of the tool used in a case study of a 16th Century stone masonry church located in the main square of Cusco; Southern Peru. This case study validates the qualitative metrics of the present work, and indicates that the tool provided accurate results when compared to the ground truth, which could be helpful in future research studies in order to automatize crack monitoring. |
