Special Issue Information

Dear Colleagues,

The field of infrastructure health monitoring is undergoing transformative advancements driven by the emergence of novel sensors, AI-driven algorithms, and innovative technologies. This Special Issue is dedicated to showcasing the latest research and developments in these areas, with a specific focus on their applications in monitoring, controlling, and assessing critical infrastructures, including bridges, buildings, and other civil engineering structures.

We invite submissions that delve into various aspects of this field, including the development and deployment of innovative sensor technologies, particularly low-cost options, that address the unique challenges of structural health monitoring. Contributions that highlight the integration of artificial intelligence (AI) into enhancing data analysis, anomaly detection, and predictive maintenance are particularly welcome. Additionally, research on the fusion of sensor data with AI to boost the accuracy and reliability of monitoring systems, as well as advancements in modal analysis methods, will be emphasized. Furthermore, this Special Issue seeks to explore the validation and calibration of low-cost sensors and the application of emerging technologies such as the IoT, digital twins, and edge computing. We aim to gather insights into the future directions and challenges within these dynamic and rapidly evolving fields.

Crack monitoring in concrete structures is essential to maintaining structural integrity. Therefore, this paper proposes a mobile ground robot equipped with a 2-DoF manipulator and stereo vision sensors for autonomous crack monitoring and mapping. To facilitate crack detection over large areas, a 2-DoF motorized manipulator providing linear and rotational motions, with a stereo vision sensor mounted on the end effector, was deployed. In combination with a manual rotation plate, this configuration enhances accessibility and expands the field of view for crack monitoring. Another stereo vision sensor, mounted at the front of the robot, was used to acquire point cloud data of the surrounding environment, enabling tasks such as SLAM (simultaneous localization and mapping), path planning and following, and obstacle avoidance. Cracks are detected and segmented using the deep learning algorithms YOLO (You Only Look Once) v6-s and SFNet (Semantic Flow Network), respectively. To enhance the performance of crack segmentation, synthetic image generation and preprocessing techniques, including cropping and scaling, were applied. The dimensions of cracks are calculated using point clouds filtered with the median absolute deviation method. To validate the performance of the proposed crack-monitoring and mapping method with the robot system, indoor experimental tests were performed. The experimental results confirmed that, in cases of divided imaging, the crack propagation direction was predicted, enabling robotic manipulation and division-point calculation. Subsequently, total crack length and width were calculated by combining reconstructed 3D point clouds from multiple frames, with a maximum relative error of 1%. Full article
