Abstract: Because of the limited view of data of each single laser scan, multiple scans are required to cover all scenes of a large construction site, and a registration process is needed to merge them together. Although many research ...

Abstract: Crane operators often face poor visibility and collision hazards during lifting operations. Dynamic three-dimensional (3D) modeling of the crane workspace helps to alleviate this by identifying potential collision hazards ...

Abstract: Construction progress estimation to ensure high productivity and quality is an essential component of the daily construction cycle. However, using three-dimensional (3D) laser-scanned point clouds for the purpose of measuring ...

Abstract: Recognizing construction assets (e.g., materials, equipment, labor) from point cloud data of construction environments provides essential information for engineering and management applications including progress ...
