UTILIZATION OF 3D LASER SCANNER IN DETECTING STRUCTURAL DAMAGE

Abstract

There are numerous factors that can potentially cause deterioration within a structure. For example, changes in weather, ageing of a structure, solar radiation, infiltration, humidity and more are just a few to be named that can play a role in deteriorating any platforms. Therefore, monitoring and maintaining such damages are important, especially for those buildings that are historically significant. The traditional way of monitoring and maintaining are based on visualizing the damage and human expectations. It is considered to be time-consuming, unprecise and could be dangerous if the considered building is large and of high altitude. Recently, a number of studies have been published proposing the use of remote sensing tools to ease the maintaining and monitoring process. Terrestrial Laser Scanner (TLS) has been utilized in most of the studies due to their high-reliability data that the machine can provide, and its ability to detect small damages and cracks, up to the millimetre level. Research conducted for this project proposed a new way for dealing with damages and estimating the missing volume from the structure using terrestrial laser scanner data; therefore, different trials have been done within different objects and walls in order to prove the method that this research proposes. In addition to this research, Cut and Fill maps will be produced as a result of all of the tests that have been done.
