Photogrammetry for Archaeology: Collecting Pieces Together

Abstract

The complexity of retrieving and understanding the archaeological data requires to apply different techniques, tools and sensors for information gathering, processing and documenting. Archaeological research now has the interdisciplinary nature involving technologies based on different physical principles for retrieving information about archaeological findings. The important part of archaeological data is visual and spatial information which allows reconstructing the appearance of the findings and relation between them. Photogrammetry has a great potential for accurate acquiring of spatial and visual data of different scale and resolution allowing to create archaeological documents of new type and quality. The aim of the presented study is to develop an approach for creating new forms of archaeological documents, a pipeline for their producing and collecting in one holistic model, describing an archaeological site. A set of techniques is developed for acquiring and integration of spatial and visual data of different level of details. The application of the developed techniques is demonstrated for documenting of Bosporus archaeological expedition of Russian State Historical Museum.

Care of Ancient Human Remains. Conservation and Management With 3d Modeling and DBMS

“…For the purposes of suitable anthropological documentation, aimed at the morphological, morphometric, palaeopathological and biomechanical study of individual bone remains, there was a need for the calibration of the photographic instrumentation with high resolution, that is, able to guarantee a high accuracy of the anatomical details. At the same time, in the phase of elaboration of the polygonal/three-dimensional model (Reverse Modeling) particular attention was paid to the editing phase (Chibunichev, Knyaz, Zhuravlev & Kurkov, 2018;Seguchi & Dudzik 2019). This is because software or non-specialized operators in the anthropological field could correct the various geometries by adopting parameters connected with the aesthetic rendering of the 3D product, effectively homogenizing the surfaces, decimating the meshes and closing the gaps.…”

3d Reconstruction and Image Processing of Anthropological Archaeological Findings

“…Non-contact measurement techniques are widely implemented today on various stages of archaeological research (starting from the initial phases of excavations to documenting, analysing and restoration of findings) and preserving cultural heritage (Badiu et al, 2015;Chibunichev et al, 2018;Scianna and La Guardia, 2018;Vasilyev et al, 2019). Usually, the material used for studies in archaeology, anthropology or palaeoanthropology is unique and requires significant effort to obtain, preserve as well as to study.…”

Results of Researches on Photogrammetric Calibration of the Sony Cyber-Shot DSC-Rx1rm2 Camera

“…Other approach, which yields good results is calibration on the basis of the geodetic test field. Today non-metric cameras are widely applied in different applications using unmanned aerial vehicles for 3D measurements (Chibunichev et al, 2018), (Knyaz and Zheltov, 2018) . Taking into account that non-metric cameras are manufactured of the materials subjectd to deformations as a result of changes of the external environment (pressure, temperature, humidity) and not always soft landings of unmanned aerial vehicles, calibration it is necessary to carry out rather often to check interior orientation parameters of the camera.…”
