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…
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…
Indoor Testing and Simulation Platform for Close-distance Visual Inspection of Complex Structures using Micro Quadrotor UAV
Zhexiong Shang, Zhigang Shen
In recent years, using drone, also known as unmanned aerial vehicle (UAV), in close-distance visual inspection has became an active area in many disciplines. However, many challeng…
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…
Real-time 3D Reconstruction on Construction Site using Visual SLAM and UAV
Zhexiong Shang, Zhigang Shen
3D reconstruction can be used as a platform to monitor the performance of activities on construction site, such as construction progress monitoring, structure inspection and post-d…
Multi-point Vibration Measurement for Mode Identification of Bridge Structures using Video-based Motion Magnification
Zhexiong Shang, Zhigang Shen
Image-based vibration mode identification gained increased attentions in civil and construction communities. A recent video-based motion magnification method was developed to measu…
