| dc.description.abstract | Unmanned Aerial Vehicle-systems (UAVs) or Drones have reserved an important
place in the construction and engineering industries over the last few decades.
Drones are employed in various parts of the construction and engineering
industries, including project creation, project management, and inspection,
construction surveying, construction safety, construction inspection, volume
measures, modeling in 3D, and other related services. UAV technical advancements
and structure from motion methodologies have resulted in UAVs being typical
platforms for 3D data collecting. Drones appear to be an ideal choice for urban
applications due to their flexibility and capacity to reach inaccessible urban areas.
Reconstructions from drone data have the potential to drastically reduce labor costs
for rapid upgrades of already reconstructed 3D cities. However, a rigorous quality
assessment is required, particularly when updating existing scenes acquired from
different sensors. Many authorities demand as-built surveys to prove the placement
of a facility at a specific moment in time. These are vital for the site's upkeep and
future expansion. A total station was employed to accomplish this task in the past,
but it is more expensive, time consuming and requires more qualified surveyors to
complete. The objective of this research is to examine the use of an Unmanned Aerial
Vehicles (UAV) system for façade surveying in Sri Lanka. The findings demonstrate
that the UAV's ability to produce as-built survey mapping, and that it also simplifies
as-built survey work by saving time and eliminating the need for trained surveyors.
As a result, UAVs are ideal for engineering tasks. | en_US |
