Extraction of pipes and flanges from point clouds for automated verification of pre-fabricated modules in oil and gas refinery projects

Highlights Development of an automated framework to detect pipes and flanges from point clouds of pre-fabricated oil and gas modules. Proposed system tested on two point cloud datasets, acquired from separate sites with different data quality and density. Proposed...

Accuracy assessment of Ultra-Wide Band technology in tracking static resources in indoor construction scenarios

Highlights Experiments were conducted to study the reliability of UWB on construction sites. In each experiment, the impact of a sub-optimal condition was simulated. For each experiment, accuracy of the location estimation data was calculated. Effects of a change in a...
