Bridge Pillar Defect Detection using Close Range Thermography Imagery

Currently, radiometric thermography image has been explored adequately as alternative advance Non-Destructive Testing (NDT) especially for early detection analysis in various applications. Systematic calibration, higher spatial resolution and high degree order processing, imagery potential to be used concrete structure defect detection. Therefore, this study is carried out examine the on bridge pillar surface using drone-based sensor (7–13 µm). Close range remote sensing NDT based drone platform segmentation have applied interpret crack line two pillars at North-South Expressway Central Link (ELITE) Highway. As a result, support by multispectral (RGB) successfully delineate micro K-means clustering method. Overall, shows optional that potentially forensic tall building.
