Special Issue Information

Dear Colleagues,

Important developments in computer vision and machine learning-based sensing, including 2D imaging, 3D laser technologies, smartphones, and unmanned aerial vehicles (UAV), have created new possibilities for monitoring infrastructure. These technologies are rapidly transforming the fields of infrastructure condition assessment, nondestructive evaluation, and structural health monitoring of various infrastructures, including roadways, bridges, airports, ports, etc.  These sensing systems generate a large amount of high-resolution data, and AI-driven data analytics and machine learning techniques are being leveraged to process this data deluge and help turn raw data into actionable information and cost-saving decisions. Collectively, these technologies are emerging as the building blocks of digital transformation, cyber-physical systems, and smart city paradigms.

This Special Issue focuses on the latest developments in sensing and data analytics for infrastructure condition assessment and automated inspections. The primary objective of this Special Issue is to explore these exciting advancements, highlight the emerging frontiers of research in this area, and set the agenda for future research. Topics of interest in this session include, but are not limited to, infrastructure sensing, structural health monitoring (SHM), infrastructure condition assessment, machine learning and deep learning applications, computer vision-based assessment, feature extraction and data fusion, automated and robotic inspection using unmanned aerial and ground vehicles, vehicle-mounted roadway inspection, digital image correlation, and other advanced data-centered methods and technologies.

Bridges are often at risk due to the effects of natural disasters, such as earthquakes and typhoons. Bridge inspection assessments normally focus on cracks. However, numerous concrete structures with cracked surfaces are highly elevated or over water, and is not easily accessible to a bridge inspector. Furthermore, poor lighting under bridges and a complex visual background can hinder inspectors in their identification and measurement of cracks. In this study, cracks on bridge surfaces were photographed using a UAV-mounted camera. A YOLOv4 deep learning model was used to train a model for identifying cracks; the model was then employed in object detection. To perform the quantitative crack test, the images with identified cracks were first converted to grayscale images and then to binary images the using local thresholding method. Next, the two edge detection methods, Canny and morphological edge detectors were applied to the binary images to extract the edges of the cracks and obtain two types of crack edge images. Then, two scale methods, the planar marker method, and the total station measurement method, were used to calculate the actual size of the crack edge image. The results indicated that the model had an accuracy of 92%, with width measurements as precise as 0.22 mm. The proposed approach can thus enable bridge inspections and obtain objective and quantitative data. Full article
