Our device for surface acquisition includes an entire system of photogrammetry based on the capture of photographic images and their reconstruction in 3D. This device includes a NIKON D7200 camera associated with a NIKKOR lens (60 mm – F/2.8G ED), as well as a Cognisys StackShot automated rail system allowing for the movement (field depth) and rotation of the object under study. The 3D reconstitution of the object is performed with Photoscan software (AJsoft).
Acquisition and processing of 3D images are nowadays at the heart of paleontology as they allow collecting raw data (anatomical virtual models of fossils from collections stored in France and abroad, osteological models for comparative analysis) as well as performing shape analyses (geometric morphometrics, internal structures, fossil reconstitution and retrodeformation…). The photogrammetry is a simple way to acquire 3D surface and textural data for both fossil material and field data.
The available material has been acquired by co-fundings from the CNRS and the University of Poitiers.
