Documentation of Cultural Heritage with Backpack Lidar Usage on Photogrammetric Purpose

Abstract

Architectural documenting is an essential requirement to identify the evidence of historical artefacts, be instrumental in their transmission to future generations, and document the destructions they have suffered. With photogrammetric methods in recent years, a new perspective has been given to survey investigations. The data obtained by 3D modelling can be collected in the digital environment and presented visually. 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
