Experimentální určování vlhkosti podzemních konstrukcí pomocí 3D skeneru

Abstract

This bachelor's thesis explores the use of using point clouds, obtained via laser scanning, to determine the moisture content of underground and geotechnical concrete structures. The experimental phase was conducted under laboratory conditions, where the moisture levels of concrete samples were first measured using a capacitive moisture meter, followed by 3D scanning of the specimens. The collected laser intensity data were subsequently processed and used to establish a regression relationship between the intensity of the backscattered signal and the actual moisture content of the concrete. The proposed procedure was then validated through in situ control measurements on an underground and geotechnical structures under suitable conditions.
