“…Even though application of the approach is not time-consuming, the area of interest and its close surroundings must be thoroughly cleaned and camera angles must not be changed abruptly when photographing. The use of a planned work-flow is thus highly recommended (De Reu et al 2014;Dellepiane et al 2013). Work-flows regarding digital technologies on a site level are being formulated and constantly tested (i.e.…”

“…Work-flows regarding digital technologies on a site level are being formulated and constantly tested (i.e. De Reu et al 2014;Dellepiane et al 2013;Katsianis et al 2008). Also, archaeologists already photograph contexts and findings in the field, often as complements to drawings, so it takes little time to adjust and freely work with this method.…”

“…The technicalities and steps for processing imagebased 3D modeling can be found in other works (De Reu et al 2014;Remondino and El-Hakim 2006). Here, processing involved data extraction, meshing and scaling following Dellepiane et al (2013:205).…”

“…The software recognizes local features in the photos during data extraction by aligning the images and during calculation of the model. These photos are matched to calibrate and orient the images, resulting in a point cloud of a triangulated surface (De Reu et al 2014;Dellepiane et al 2013). Meshing and coloring involves matching every pixel to recreate coordination in digital three-dimensional space.…”

During the last twenty years archaeology has experienced a technological revolution that spans scientific achievements and day-to-day practices. The tools and methods from this digital change have also strongly impacted archaeology. Image-based 3D modeling is becoming more common when documenting archaeological features but is still not implemented as standard in field excavation projects. When it comes to integrating zooarchaeological perspectives in the interpretational process in the field, this type of documentation is a powerful tool, especially regarding visualization related to reconstruction and resolution. Also, with the implementation of image-based 3D modeling, the use of digital documentation in the field has been proven to be time- and cost effective (e.g., De Reu et al. 2014; De Reu et al. 2013; Dellepiane et al. 2013; Verhoeven et al. 2012). Few studies have been published on the digital documentation of faunal remains in archaeological contexts. As a case study, the excavation of the infill of a clay bin from building 102 in the Neolithic settlement of Ҫatalhöyük is presented. Alongside traditional documentation, infill was photographed in sequence at each second centimeter of soil removal. The photographs were processed with Agisoft Photoscan. Seven models were made, enabling reconstruction of the excavation of this context. This technique can be a powerful documentation tool, including recording notes of zooarchaeological significance, such as markers of taphonomic processes. An important methodological advantage in this regard is the potential to measure bones in situ in for analysis after excavation.

“…The current major shift in 3D mapping and 3D modeling is due to proven computer vision technologies based on Structure from Motion (SFM) and Dense Stereo Matching (DSM) algorithms (Verhoeven 2011;Verhoeven et al 2012;De Reu et al 2013;De Reu et al 2014). SFM and DSM proved to be reliable technologies that can be used to process large datasets of aerial photographs captured by uncalibrated digital cameras mounted on lightweight aircrafts flying GPS waypoint missions.…”

Image-based modelling (IBM) applications can be used to successfully extract two-and three-dimensional information from historic aerial and satellite imagery for use in archaeological and other landscape-oriented research. The robust and highly automated nature of these applications can allow for image matching and dense scene reconstruction, even when input images lack information necessary for processing in traditional photogrammetric workflows. However, the overall quality of the content derived from IBM applications can be directly influenced by a number of variables, including the manner in which archival content is digitized. Significant geometric distortion can be induced in the scanning process when using non-photogrammetric scanning devices, which can have a negative effect on the subsequent processing of scanned imagery and accuracy of derived content such as orthomosaics and digital elevation models (DEMs). While this is a well-known issue for users of high end photogrammetry packages, the advent of IBM applications has brought the use of photogrammetric-style techniques to a wider audience who may not be aware of the impact that geometric errors of this nature can have on the quality of derived data products. This issue is demonstrated here using a set of degraded historic World War II (WWII) Allied reconnaissance photographs that have been digitized on both photogrammetric and nonphotogrammetric platforms and subsequently processed in a well-known IBM application using identical processing parameters. The results are compared to those from a recently collected set of vertical stereopairs and an airborne laser scan derived DEM.
