Quantitative analysis of blind tower-crane lifts using laser-scanning information
TL;DR: In this article, the authors used laser scanning data to quantitatively assess blind lifts with respect to their rate and spatial distribution, and found that 28 per cent of the analyzed crane's work area represented by the model were found to be invisible.
Journal ArticleDOI
Classification of photogrammetric point clouds of scaffolds for construction site monitoring using subspace clustering and pca
TL;DR: An approach for the classification of photogrammetric point clouds of scaffolding components in a construction site, aiming at making a preparation for the automatic monitoring of construction site by reconstructing an as-built Building Information Model (as-built BIM).
