An Approach for Occlusion Detection in Construction Site Point Cloud Data

Data collected using laser scanners on construction sites often include regions in 3D space that cannot be observed beyond occlusions, which are objects in the line of sight of the scanner. These occlusions may exist even if scans are planned using a scan-planning algorithm. The issue of occlusion can prevent accurate modeling of objects in a scan, requiring potentially costly decisions to revisit the site for additional scans. Computational …
