Abstract

Technological developments provide new methods for the measurement of 3D point data and information extraction from them. Terrestrial laser scanning is the latest method to 3D surveying and modeling. All geometric information belonging to the object or scene can be extracted from terrestrial laser scanner (TLS) data. The aim of this work is measurement of wall thickness of a building, which was built to protect the Alaaddin Palace, creating of cross-section by laser scanning data. We surveyed the building by TLS and performed 3D model. Then cross-sections were created from point clouds to measurement wall thickness of concrete building.

Key words: Terrestrial laser scanner, concrete building, cross-section, 3D modeling, wall thickness, Alaaddin Palace.
