Abstract

In this study, the intensity value was derived from the results of data acquisition using TLS, which were then registered to determine which scanworlds overlapped as a criterion for selecting the intensity value sample. The obtained intensity values are influenced by geometrical factors and the material composition of the object. Because the intensity value is used to identify and classify the various materials that comprise an object, it is necessary to conduct research on the intensity value because it can support in detecting structural damage to buildings or in asset management. The identification process was carried out in this study using the windows scan method. The classification process relates to the intensity value that each material acquires, which is determined during the identification process. Materials with similar or identical intensity values will be classified together. The study's findings indicated that an intensity value within a specific classification range indicated the presence of material on the research object in the form of concrete walls, wooden doors, wooden windows, and glass lamps.
