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

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.     

Documentation of the Yazdi-Bandi Vault at the Plaza of Sadr-e-A’zam,Tehran

ABSTRACT

This article intends to document a previously unsighted sample of yazdi-bandi over an outlying structure in the old Bazaar fabric of Tehran, namely a plaza known as Timché-ye Sadre-A’zam. Recent renovations of the plaza have concealed the work under an austerely flat drop ceiling in gypsum. The old yazdi ceiling was only accidentally discovered by the authors following the trail of hearsay and local legends. The plaza is of late 19th century construction, a period that witnessed an evolutionary and aesthetic climax in all aspects of architectural geometry in the country, including the various branches of kaarbandi. With the limitations that the authors faced, basic tools were used in the scanning and surveillance of the ceiling. Photographs were collected using a wide-angle lens. They served as raw data for the reconstruction of the yazdi plan in AutoCAD, This article presents the findings, and for a better understanding of the entire premise by the reader, supplements them with preambles on the evolutionary history, geometrical analysis, a preview of the state of scholarship and a collection of relevant terms and concepts in the study of yazdi, in particular, and kaarbandi as a whole.
