Documentation of cultural heritage with backpack lidar usage on photogrammetric purpose

Abstract

Modelling historical artefacts' external and internal structures together is a task that can be done with many sessions with classical terrestrial laser scanners. Backpack Lidar Systems are a proper newly applied alternative method in large areas of use and historical buildings where many sessions should be held with terrestrial laser scanner systems. These systems quickly acquire coordinate data and omega, kappa and phi angles differences with internal GNSS / IMU components and save time and cost following photogrammetric mentality. In this research, using Backpack Lidar System; The exterior and interior structure of the village mosque, which is an Ottoman artefact built in 1899 at the Dumanoluğu Village in the Şiran District of Gümüşhane City, was modelled in 3D. With its integrated camera, the point data has been coloured and made suitable for architectural survey studies. The village mosque's exterior scan was completed within seven minutes, and the interior scan within five minutes. 2.041.971 points were obtained in the external scanning, and 821.306 points in the internal scanning. Four GCPs were used for the mosque's exterior screening. The point clouds obtained were combined and modelled.
