Agisoft Metashape
Description
First, we took 72 photographsusing a full frame camera Nikon D7200 (lens Tamron 24-75mm, F2.8). Each photograph was taken in two elevation positions to fully cover the surface of the samples. Obtained images were then used for reconstruction of 3D photogrammetric models through Agisoft Metashape PRO 1.7.1. This procedure was complemented with scans using the geo-referenced marker grid matrix, which provides a greater precision (and automation of the reconstruction process) than the usual geo-referencing of the model through one or more scale bars.
