| dc.description.abstract | The purpose of this research is to create a
methodology that facilitates and speed up the
collection of data in order to quantifiably determine
the progress of construction work, through the use
of drones and commercial Structure from Motion
software, so that it could be affordable for small
and medium construction companies.
The equipment and the software were
selected based on a quality / price ratio. A guide
was presented, explaining the way of taking data,
its process and photogrammetric products
(ortomosaics, 3D models, etc.). Finally, the
technique proposed in the guide was validated
through a real case where the progress of an
activity was quantified. In conclusion, if what is
going to be measure tolerates precisions up to
1/1000, the technique is applicable.
The results of this methodology do not
intend to displace conventional methods such as
topography, but the manual collection of some
data, because it is possible to generate reliable,
fast, inexpensive, and accurate metric information.
For these reasons, it can be an everyday tool for
the construction engineer, with extra gains in job
security, accessibility and the possibility of creating
visual support material for a better understanding
with clients, consultants and field workers. | |
