Established in 2014, the Zinman Institute of Archaeology’s Photogrammetry laboratory specializes in 3D modeling, mapping and reconstruction of archaeological data. The lab, operated by Eli Gershtein, provides a wide spectrum of archaeological documentation, from an entire large scale site to macro photogrammetry of small finds.
The lab uses photogrammetric reconstruction based on SFM (Structure from Motion) algorithms. SFM is a method of extracting a 3D structure from many overlapping digital images, using various mathematical algorithms to compute the change in position of the camera and enable a way to calculate and triangulate the 3D positions of overlapping pixels in different images.
The lab provides services for the institute's scholars as well as for scientific projects in Israel and abroad including excavations, surveys, archaeological laboratories and museums. The lab provides a full package of field and laboratory services:
MappingOne of the basic uses of photogrammetry in archaeology is high quality mapping of sites before, during, and after excavation and/or survey work. We provide general and topographic maps, site plans, building and locus plans, digital elevation models and visual representation of the studied buildings and sites.
These results may be obtained through your own photographs or by the lab specialist using various techniques and methods including drone photography (depending on size and topography). Results are provided in high resolution of up to an accuracy of a few millimeters. The desired map or site plan are then accurately geo-referenced for integration into a general site map and exported into the desired format (i.e. JPG, TIFF, PNG, KMZ).
Small findsThe lab provides photography services of small finds for later digitizadtion and 3D modeling which creates an easy and precise tool for measurements of features and angles that are otherwise difficult and tedious to obtain. The data, whether made in our lab or based on yours photo data is modeled and exported into various file formats (i.e. OBJ, 3DS, PDF, CAD). Once exported, the objects can be easily analyzed on your own computer, catalogued for conservation and future reconstruction if needed. This is particularly important in cases of damage or loss of finds.
Photography for modeling on siteIf you prefer to supply us with your own site photography without using the lab’s photography services, you can contact us via e-mail for guidelines. Workshops may also be arranged for hands-on training.This technique has begun to replace the need for manual drawing of sites and small finds. Unlike laser based modeling, photogrammetry is cheaper and provides photorealistic models, accurate point cloud, and 3D mesh data.
- The photogrammetry is a cost effective technique that had been refined in our lab for archaeological services. The results are already replacing the need of many of the site manual drawing, and replace the need of drawing unique small finds. Unlike laser based modeling photogrammetry is by far cheaper and provides photorealistic models and accurate point cloud and 3D mesh data.
- The photogrammetric data obtained from these services can be exported to a variety of formats for publication, visualization, presentation and incorporation to a web site. These formats include geo-referenced maps, digital elevation model maps, 3D models and/or work data, as well as video clips and photorealistic isometric views of the results.
- The photogrammetry laboratory in the University of Haifa is a versatile, cost effective, and mandatory tool for today's archaeological research.
