“…The models that were created were compared with models from a NextEngine triangulation laser scanner. Focus stacking and photogrammetry were also used to record the 3D information about the millimetric and submillimetric details in 3D of prehistoric petroglyphs and paintings (Plisson & Zotkina 2015). Kontogianni et al (2017) used focus stacking to investigate the effect of the technique on SfM-MVS 3D reconstruction.…”

ABSTRACT:The 3D digitisation of small artefacts is a very complicated procedure because of their complex morphological feature structures, concavities, rich decorations, high frequency of colour changes in texture, increased accuracy requirements etc. Image-based methods present a low cost, fast and effective alternative because laser scanning does not meet the accuracy requirements in general. A shallow Depth of Field (DoF) affects the image-based 3D reconstruction and especially the point matching procedure. This is visible not only in the total number of corresponding points but also in the resolution of the produced 3D model. The extension of the DoF is a very important task that should be incorporated in the data collection to attain a better quality of the image set and a better 3D model. An extension of the DoF can be achieved with many methods and especially with the use of the focus stacking technique. In this paper, the focus stacking technique was tested in a real-world experiment to digitise a museum artefact in 3D. The experiment conditions include the use of a full frame camera equipped with a normal lens (50mm), with the camera being placed close to the object. The artefact has already been digitised with a structured light system and that model served as the reference model in which 3D models were compared and the results were presented.

ABSTRACT:The Depth of Field (DoF) is a vital factor in photogrammetric applications. Its effect is in most cases pretty obvious especially when capturing small artefacts. It is very important to observe its behaviour as it affects the ability to capture all the details of an object. Focus stacking is a technique in computational photography, in which a set of images focused on different planes with limited DoF are combined in order to considerably extend the DoF. Today, there is a number of focus stacking methods that can be applied in order to produce a full-focus image. In this paper, we investigate the application and effects of focus stacking on SfM-MVS 3D reconstruction. Specifically, our experiment involves the 3D reconstruction of a selected artefact using both traditional all-focus photography and focus stacking. The artefact has already been digitised with a high accuracy and resolution structured light 3D scanner, and that 3D model served as the reference model, with which SfM models were compared. We discuss on these fist results and present some preliminary assessment on the application of focus stacking for the SfM-MVS-based 3D reconstruction.

“…As soon as they are posted online, they will become accessible to any turkologist around the world, thus giving a new impetus to progress in deciphering. Besides, the project will bring into sharp focus the long-term benefits of using 3D recording for the preservation and popularization of archaeological and epigraphic heritage in Russia, where such projects are extremely rare today (Plets et al, 2012;Zaytseva, 2014;Plisson and Zotkina, 2015;Pushkarev et al, 2016;Zaitceva et al, 2016 ).…”

ABSTRACT:Old Turkic runic inscriptions of the Altai Mountains (8th-9th centuries AD) were digitized in the course of this project to be preserved in the current state on the Web and deciphered by linguistic experts. The ways the inscriptions were made as well as their location in hardly accessible areas required finding an inexpensive solution that would provide detailed 3D documentation of rock faces, while at the same time mobility and autonomy. Digital photogrammetry came as a quite affordable and optimal choice for getting high-quality outcomes using inexpensive software and further data processing using free software.
