Abstract: Flaggers are always required to work close to open traffic lanes. They may be hit by distracted, speeding, or intoxicated drivers, leading to injuries and fatalities. To protect them, the concept of an automated flagging ...

Abstract: Three-dimensional (3D) as-built geometric models are useful for many building assessment and management tasks. However, the current process of creating such models is labor-intensive. A significant amount of manual work ...

Abstract: Infrastructure modeling refers to the process of collecting infrastructure spatial data and transforming them into structured representations. It is useful during all stages of the infrastructure life cycle, and plays an ...

Abstract: The automated detection of structural elements (e.g., columns and beams) from visual data can be used to facilitate many construction and maintenance applications. The research in this area is under initial investigation. ...

Abstract: Manually inspecting concrete surface defects (e.g., cracks and air pockets) is not always reliable. Also, it is labor-intensive. In order to overcome these limitations, automated inspection using image processing techniques ...

Abstract: Moisture marks (wet areas) are significant defects that may develop on the surfaces of subway structures as a result of water leakage through soil. The detection and assessment of moisture marks are predominantly conducted ...

Abstract: As-built models have been proven useful in many project-related applications, such as progress monitoring and quality control. However, they are not widely produced in most projects because a lot of effort is still necessary ...

Abstract: Excavators and trucks are important equipment for earthwork operations, which make major contributions to construction productivity. To control the work efficiency and productivity of earthwork equipment, computer vision ...
