Title: Structural Health Monitoring with advanced deep learning and autonomous UAVs.
Abstract: 
This online seminar provides deep learning-based structural health monitoring from crack classification, multiple types of damage classification, volumetric quantification of concrete spalling, crack segmentation, autonomous UAV methods, and their integrations. This presentation introduces deep learning-based approaches for structural health monitoring (SHM) applications. It will introduce a convolutional neural network (CNN) based crack classification, and a faster based CNN (faster R-CNN) based multiple types of damage detection for civil infrastructures to detect and localize the detected damage using bounding boxes. The faster R-CNN was also applied for concrete spalling damage detection for volumetric quantification using depth camera. Autonomous flight method of UAV is introduced to integrate it with deep learning-based damage detection. Subsurface damage detection is introduced using deep learning and thermography. Damage segmentation methods (SDDNet and STRNet) are introduced to detect cracks in pixel level in complex background scenes with real-time manner. These advanced deep learning-based methods overcome the limitation of traditional computer vision-based methods. It also opened the new door for fully automated SHM.
