Combining photogrammetry and laser scanning for the recording and modelling of the Late Intermediate Period site of Pinchango Alto, Palpa, Peru

Abstract

This paper describes the 3D modelling of Pinchango Alto, Peru, based on a combination of image and range data. Digital photogrammetry and laser scanning allow archaeological sites to be recorded efficiently and in detail even under unfavourable conditions. In 2004 we documented Pinchango Alto, a typical site of the hitherto poorly studied Late Intermediate Period on the south coast of Peru, with the aim of conducting spatial archaeological analyses at different scales. The combined use of a mini helicopter and a terrestrial laser scanner, both equipped with a camera, allowed a fast yet accurate recording of the site and its stone architecture. In this paper we describe the research background, the 3D modelling based on different image and range data sets, and the resulting products that will serve as a basis for archaeological analysis.

Terrestrial Laser Scanning in the Age of Sensing

“…In the last decade, lightweight Unmanned Aerial Vehicles have been employed in archaeology to create 3D models of built structures, orthophotos and digital elevation models (Lambers et al 2007;Guidi et al 2008).…”

Rpas and TLS Tecniques for Archaeological Survey: The Case Study of the Archaeological Site of Eraclea Minoa (Italy)

“…Today RPAS (Remotely Piloted Aircraft System) and TLS (Terrestrial Laser Scanning) survey are standard approach to produce high quality point cloud and 3D model in archaeological context with reduced execution times and great metric reliability. The capabilities of RPAS and TLS for the documentation of archaeological sites has been demonstrated in several different case studies (Lambers et al, 2007;Sauerbier & Eisenbeiss, 2010;Hendrickx et al, 2011;Lo Brutto et al, 2012;Guidi et al, 2014;Lo Brutto et. al., 2014;Galeazzi, 2016;Nikolakopoulos et al, 2016).…”

Photogrammetry and Laser Scanning for Reconstruction and Restoration of Historical Buildings

“…Combination of laser scanning data and Photogrammetry is interesting for foreign researchers also, such as Alshawabkeh Y., Haala N., Nuttens T., De Maeyer P., De Wulf A., Goossens R., Stal C., Baltsavias E.P., Ravanel L., Curtaz M., [5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23], who apply these methods in archaeological works and projects of historically important architectural objects archiving. Besides, researchers in other fields of science, such as a mine surveying [24] and mechanical engineering are engaged in studying of this problem [25].…”
