3D models of bead, pendant and softstone vessel fragments found during the 2021 excavations at Kalba (K4)

The 3D models of the three objects were created within the joint excavations project at Kalba (K4), United Arab Emirates, of the Sharjah Archaeology Authority (SAA), the Austrian Archaeological Institute (OeAI) of the Austrian Academy of Sciences (OeAW) and the Leibniz-Zentrum für Archäologie (LEIZA).

For each object the following data are available: 3D model with colour values reflecting the curvature (MSII filter) in ply format, texture image for the 3D model in png format, metadata of the 3D acquisition and processing in ttl and json format.

The 3D models were created with the Structure from Motion (SfM) technique using Agisoft Metashape software. The images were taken with a Nikon Z50 mirrorless camera and a 90 mm lens. The models obtained were post-processed using GigaMesh (https://gigamesh.eu) to calculate curvature with the MSII built-in filter and to create scaled 2D views. The export of the 3D metadata with information about the 3D model and the 3D acquisition and processing was done with pyhton scripts in agisoft metashape (https://doi.org/10.5281/zenodo.7468298).
