Featured Application This work proposes a semi-automatic approach for the 3D
reconstruction of existing buildings from point clouds in the context of BIM. This process …

This paper presents an automated and effective method for detecting 3D edges and tracing
feature lines from 3D-point clouds. This method is named Analysis of Geometric Properties …

An automated image capturing and processing system and method may allow a field user to
operate a UAV via a mobile computing device to capture images of a structure area of …

Due to a higher efficiency and lower cost, prefabricated construction is gradually gaining
acceptance within the market. Laser scanning has already been adopted in civil engineering …

Traditional documentation capabilities of laser scanning technology can be further exploited
for urban modeling through the transformation of resulting point clouds into solid models …

Despite the increasing demand of updated and detailed indoor models, indoor
reconstruction from point clouds is still in an early stage in comparison with the …

With increasing urbanization, flooding is a major challenge for many cities today. Based on
forecast precipitation, topography, and pipe networks, flood simulations can provide early …

The extraction of object features from massive unstructured point clouds with different local
densities, especially in the presence of random noisy points, is not a trivial task even if that …

ABSTRACT Three-dimensional (3D) reconstruction of a building can be facilitated by
correctly segmenting different feature points (eg in the form of boundary, fold edge, and …

Laser scanning technology is a fast and reliable method to survey structures. However, the
automatic conversion of such data into solid models for computation remains a major …
