Robust concrete crack inspection using terrestrial laser scanning / Muhammad Ikhsan Irwanshyah

Crack is one of the reasons why the deformation survey must be done to the
building facade. Inspections need to be done in order to reduce risks and determine
whether the building safe to live in or use. There are many ways to measure the crack
but in this research is focusing on measuring the crack using the terrestrial laser
scanner. The conventional method had a few limitations to measure the crack.
However, this research aims to investigate robust procedure to perform crack
inspection on building facade. The data will be collected using different laser scanner
resolutions to determine which resolution is enough to visual the crack. The crack can
be determine based on the intensity value as the crack on the building facade will give
a different intensity value when the laser point interact with the crack and return to the
laser scanner in order to record the data. Result from this research are to produce the
robust procedure for crack detection using terrestrial laser scanner. As the conclusion,
the implementation of terrestrial laser scanner is useful and effective method in crack
detection purpose.
