Abstract:
The realistic possibility in use of non-metric cameras to achieve a reliable digital 3D model has eased the application of photogrammetry in different field. Documentation, conservation and dissemination of Built Heritage can be obtained and implemented through virtual copies and replicas. Photogrammetric solutions have enlarged the feasibility of pedagogy of local people in remote regions in which the 3D surveying may be difficult or expensive. Structure-from-Motion (SfM) has proven its impressive potential for image-based 3D reconstruction resulting in great 3D point clouds’ acquisitions for minimal expense. Images from Unmanned Aerial Vehicles (UAVs) can be processed within SfM photogrammetry workflows to obtain point cloud of Cultural Heritage in remote regions. This paper presents a methodology for deriving a CH geometry directly from both aerial and terrestrial images in remote areas considering three aspects for the data - planning, acquisition, and processing. The proposed methodology was applied for the case study of Ziggurat Chogha Zanbil in Iran, where point clouds’ information were enriched by using two Oblique (or off-Nadir), Nadir and Terrestrial acquisition standpoints. Further, the obtained four point-clouds were analyzed through Cloud-2-Cloud (C2C) and Multiscale Model to Model Cloud Comparison (M3C2) methods in order to assess their accuracy.
