Abstract

The data set consists of three-dimensional (3D) models of experimentally produced lithic artifacts created using both expedient and refined photogrammetric setups and processing protocols. Source images for all models were captured using a 12.1 megapixel Canon PowerShot SX260 HS compact digital camera. In our expedient protocol, objects were placed on a wire stand. The photographer moved around the object, and captured photos using Auto mode. In our refined protocol, objects were placed on a rotating turntable under controlled lighting conditions. The camera was placed on a tripod. Shutter speed, f-stop, and ISO were set manually. This refined protocol is described in Porter, S. T., Roussel, M., & Soressi, M. (2016). A Simple Photogrammetry Rig for the Reliable Creation of 3D Artifact Models in the Field Lithic Examples from the Early Upper Paleolithic Sequence of Les Cottés (France). Advances in Archaeological Practice, 4(1), 71-86. The associated paper discusses the relative fidelity of the models produced using these different workflows.

Description

The data are divided into four ZIP files based on whether they contain core or flake models, and whether the models were created using an expedient or refined photogrammetric setup and protocol. Each of these .ZIP files contains the relevant 3D models in OBJ format. There are three files associated with each model (OBJ, MTL, and JPG texture). The files are named based on object ID, and the setup used to create them (i.e. expedient or refined). All models were processed and scaled in Agisoft PhotoScan Professional Edition. Geomagic Design X was used to center and align models around the origin.
