Using terrestrial liDAR data in 3D CAD modeling applications

Abstract

Preserving historical and cultural artifacts through generations is essential for maintaining the roots and ensuring the development of any civilization.Conservation and restoration works are crucial in order to save numerous historical and cultural heritages in our country and the world and also pass on them from generation to generation. Nowadays, the increasing development in measurement technologies and the integration of photogrammetry into architectural applications have provided different perspective in architectural documentation applications. In this context, Terrestrial laser scanning method is a current method used in documentation studies today. The most important advantages of terrestrial laser scanning in this study are as follows: -the point cloud data obtained by terrestrial laser scanners provides the opportunity to reach the correct data at the desired frequency in a short time, -obtaining appropriate and practical results for the targeted study,- the possibility of using scanners in different working areas. In this context, laser scanners have become one of the popular methods in which effective and successful results are obtained in architectural documentation projects such as survey, restitution and restoration. Within the scope of this study, ‘‘Ali Efendi Muallimhanesi’’, which is one of the historical and cultural heritage of Konya province, was scanned with a terrestrial laser scanner and a architectural survey was carried out with the help of the obtained scanning data.
