Abstract
Detection of bio-deterioration and moisture is one of the most important tasks for comprehensive diagnostic measurements of buildings and structures. Any undesirable change in the material properties caused by the action of biological agents contributes to gradual aesthetic and physical damage to buildings. Very often, such surface changes can lead to structural defects or poor maintenance. In this paper, radiometric analysis of point clouds is proposed for moisture and biofilm detection in building walls. Recent studies show that remote terrestrial laser scanning (TLS) technology is very useful for registering and evaluating the technical state of the deterioration of building walls caused by moisture and microorganisms. Two different types of TLS, time-of-flight and phase-shift scanners, were used in the study. The potential of TLS radiometric data for detecting moisture and biofilm on wall surfaces was tested on two buildings. The main aim of the research is to compare two types of scanners in the context of their use in the detection of moisture and microorganisms.
Highlights
Terrestrial laser scanning (TLS) technology has become one of the most popular methods for object acquisition in civil engineering [1,2,3,4]
Datasets were standardized to eliminate the effect of the incidence angle and distance changes on the value of intensity
We proposed the harnessing of terrestrial laser scanning (TLS) for the remote sensing and detection of saturation of building walls and microorganism colonization of a wall
Summary
Terrestrial laser scanning (TLS) technology has become one of the most popular methods for object acquisition in civil engineering [1,2,3,4]. TLS provides rapid capture of point clouds in high resolution for 3D object modelling (e.g., buildings [5,6], structures [7,8], geotechnical objects [9,10]). It can be used for the technical assessment of the surface condition of building walls [11,12,13]. Digital photographs taken by TLS provide additional help in assessing the degradation of a building wall
