THREE DIMENSIONAL MODELING OF HISTORY AND CULTURAL ASSETS BY LASER SCANNERS AND KARACABEY TOMB EXAMPLE

One of the latest techniques used in three-dimensional positioning and modeling studies is terrestrial laser scanning. This technique is used in various engineering applications such as the documentation of historical buildings, deformation surveys, mining quarry and excavation applications, industrial applications, protection of the historical heritage and archeology, disaster monitoring, coastline applications, architectural and building surveying, transportation and infrastructure. While three-dimensional position information is surveyed using terrestrial laser scanning, the texture information of the objects is recorded by digital photo cameras and video cameras. The point clouds obtained through overlapped scanning from different stations are automatically combined by means of software programs and three-dimensional models are created. In the present study, overlapped scanning of the Karacabey Tomb was performed from different stations using Faro Focus3D × 330 brand and model laser scanner. The point clouds were combined with Scene 5.3 software by using the common points obtained through the overlapped scanning of the tomb. The point clouds were colored by means of the photographs taken by the digital camera integrated in the scanner during the scanning process. The three-dimensional model of the Karacabey Tomb was obtained from the combined and colored point clouds.
