Thermal imaging coupled with high-definition colour imaging for defect localisation and quantification
Abstract »Assessing the current condition of infrastructure systems is a main concern especially nowadays since most of the existing systems are aging and deteriorating rapidly. Inspection of these systems usually require hands-on interaction by the inspectors or utilization of advanced sensor technologies. At the same time, it is usually hard to document and store the defect information with the common methodologies which, most of the times, involve manual recording of the detected damage information. This paper proposes a coupled thermal and high-resolution color imaging strategy for determining the defects on concrete structures. This proposed system aims to provide an affordable and easy to use assistant sensor solution in addition to the current inspection strategies. Thermal imaging part of the system is designed to monitor the flow of heat from the surface of the structure. The main aim is to located the regions where the flow is affected by internal flaws such as voids and etc. High-definition color imaging, on the other hand, is used for detecting cracks, efflorescence, spalling and etc. Several image processing strategies are performed in order to both locate and quantify the defects and finally, the results are compared for varying methodologies.
