Computer-vision is an emerging technology which has been widely used in the field of structural health monitoring. This seminar will cover the latest achievements of our research group in defect detection, health monitoring, and construction control using image-based technologies. For defect detection, advanced unmanned aerial vehicles (UAVs) have been developed to automatically detect surface cracks and other types of structural damages based on digital image processing techniques. An integrated navigation system combining binocular camera and inertial sensor enables automated route planning for the developed UAVs in case of GPS failure. Specifically, a wall-climbing UAV is designed to acquire detailed surface crack images with high accuracy and a collision-tolerant UAV is proposed for the defect inspection of complex or internal spaces. In addition to UAV, an unmanned ship is developed for exploration of inaccessible places such as sewers. For structural health monitoring, on-line camera monitoring system has been developed for displacement measurement of long-span bridges. For construction control, a binocular vision-based method is investigated and applied for displacement measurement during the hoisting process of prefabricated components. Experimental results show that compared to conventional methods, the proposed approach is more intelligent, more convenient, and more reliable.


Dr. Jian Zhang is currently a Professor of Civil Engineering at the Southeast University and Director of Jiangsu Key Laboratory of Engineering Mechanics. His research interests include technologies and devices for intelligent inspection and non-contact measurement, mobile rapid impact testing, and approaches for long-term monitoring data processing and uncertainty analysis. He received the 2018 Aftab Mufti Best Paper Award by the International Society for Structural Health Monitoring of Intelligent Infrastructure (ISHMII) and the 2019 Takuji Kobori Prize by the International Association of Structural Control and Monitoring (IASCM). He served as the Co-Chair of the 8th International Conference on Experimental Vibration Analysis for Civil Engineering Structures (EVACES). He has served on the editorial board of academic journals including Computer-Aided Civil and Infrastructure Engineering and Structural Control and Health Monitoring.
