ABSTRACT

А possibility of using 3D laser scanning for collecting massive volumes of
precise, high-resolution spatial data for deformation monitoring is discussed.
This paper introduces laser scanning as an instrument which may be applicable
to the field of dam deformation monitoring. The advantages of this technique
for modeling and providing a much more valid representation of the actual
surface shape are represented. Unlike traditional surveying techniques that
collect hundreds of discrete data points over a period of several days’ laser
scanners can measure several thousand points per second.
This paper introduces laser scanning as an instrument which may be applicable
to the field of deformation monitoring. Overview and principles of terrestrial
and airborne 3D laser scanning are presented. Results of a calibration
experiments are presented, providing an insight into the spatial performance of
a laser scanning instrument. Some benefits and advantages of terrestrial laser
scaning (TLS) in the field of dam deformation monitoring are given. Guidelines
instead of conclusion about the technology and postprocesing of data gathered
from TLS for its application for dam deformation monitoring are made.

Keywords: laser scanning, dam deformation, deformation analysis.
