(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 very vital for the site's upkeep
and future expansion. Total station was
employed to accomplish this duty in the past, but
it is more expensive, time demanding, and
requires more qualified surveyors to complete.
The objective of this research is to examine the
use of Unmanned Aerial Vehicles (UAV) system
for façade surveying in Sri Lanka. The study's
findings demonstrate that the UAV's ability to
produce as-built survey mapping can be
realized, 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 |
