ABSTRACT

The 3D-Digging Project started at Catalhoyuk in 2009 with the intent to digitally record and display in 3D all the archaeological stratigraphy: the case study is Building 89, a Neolithic house. The initial strategy of the 3D-Digging Project was to make comparative testing involving optical, time-of-flight scanners, phase comparison scanners, and computer vision technologies, in order to understand the performance and accuracy of the devices in relation to archaeological research questions. Methodologies and strategies at Catalhoyuk involve the use of image-based 3D modelling techniques at intra-site/micro-scale level for data recording of buildings, layers, units, features, and burials; laser scanning surveys are used for large-scale documentation. Since 2011, the field acquisition technique has been systematically employed at Catalhoyuk to generate accurate 3D digital replicas of the sequence of contexts detected during the field activities. The commercial package Agisoft Photoscan Pro 1.0 combines algorithms of Structure from Motion (SFM) and Multi-view Stereo reconstruction.
