Paper Abstract

To improve the robustness of concrete crack detection in complex environments that feature non-uniform illumination, low contrast, and stain noise, such as roads, bridges, I present a systematic approach for automatic crack detection on UAV images for monitoring concrete facilities such as buildings and civil structures. A two-step process was applied. First, a deep learning processing technique for region detection of cracks, and then crack detection based on the image processing and region properties. I applied transfer learning approach to use a pre-trained network in order to identify cracks. I used pixel value based binarization of image data with an edge-preserving filter, which reduced noise in the region. Experimental results from UAV images showed that our approach has a good potential to be applied to concrete crack detection.
