Bridge Deck Delamination Segmentation Based on Aerial Thermography Through Regularized Grayscale Morphological Reconstruction and Gradient Statistics
Chongsheng Cheng, Zhexiong Shang, Zhigang Shen
Environmental and surface texture-induced temperature variation across the bridge deck is a major source of errors in delamination detection through thermography. This type of exte…
Thermographic Laplacian-pyramid filtering to enhance delamination detection in concrete structure
Chongsheng Cheng, Ri Na, Zhigang Shen
Despite decades of efforts using thermography to detect delamination in concrete decks, challenges still exist in removing environmental noise from thermal images. The performance…
Enhancing Bridge Deck Delamination Detection Based on Aerial Thermography Through Grayscale Morphologic Reconstruction: A Case Study
Chongsheng Cheng, Zhexiong Shang, Zhigang Shen
Environmental-induced temperature variations across the bridge deck were one of the major factors that degraded the performance of delamination detection through thermography. The…
CNN-Based Deep Architecture for Reinforced Concrete Delamination Segmentation Through Thermography
Chongsheng Cheng, Zhexiong Shang, Zhigang Shen
Delamination assessment of the bridge deck plays a vital role for bridge health monitoring. Thermography as one of the nondestructive technologies for delamination detection has th…
Vision-model-based Real-time Localization of Unmanned Aerial Vehicle for Autonomous Structure Inspection under GPS-denied Environment
Zhexiong Shang, Zhigang Shen
UAVs have been widely used in visual inspections of buildings, bridges and other structures. In either outdoor autonomous or semi-autonomous flights missions strong GPS signal is v…
A Data Fusion Platform for Supporting Bridge Deck Condition Monitoring by Merging Aerial and Ground Inspection Imagery
Zhexiong Shang, Chongsheng Cheng, Zhigang Shen
UAVs showed great efficiency on scanning bridge decks surface by taking a single shot or through stitching a couple of overlaid still images. If potential surface deficits are iden…
