This course is addressed to researchers and technicians who work with complex structures and need to digitize their samples for different reasons, such as digital preservation, geometric morphometrics, biomechanics analyses, etc.
The goal of this course is to explain how you can obtain 3D virtual models from surfaces, using photogrammetry. These techniques and technologies offer the possibility to obtain 3D models of the external morphology of the samples including colour and texture of a wide size range of specimens with medium – low cost and fast approaches.
By the end of this course, participants should be able to obtain high-quality digitalization of samples with the most commonly used techniques.
They will also be able to edit and manipulate the digital models to prepare them for use in typical analytical software.
Main software that you will use during the course: Reality Capture, Agisoft Metashape, GOMinspect and Meshmixer. Temporal licences will be provided for the course.
All participants must have a computer (Windows, Macintosh, Linux). Webcam and headphones are strongly recommended, as well as a good internet connection. You will need a camera to do the exercises.
As for the equipment, we are listing from the ideal thing you may have for your research, to the minimum you need to do the practice in case you do not have access now to the ideal ones:
IDEAL: DSLR or mirrorless camera with a wide-angle lens with short minimum distance, matching LED light ring (best: SL-108).
OK: digital camera with LED light ring.
Absolute minimum: good cell phone camera.
IDEAL: Dedicated photogrammetry scale bars.
OK: any other measure, e.g. labeled cm scale.
IDEAL: turntable, ethafoam or similar, 6 to 8 raw-wooden chopsticks
OK: styrofoam, 6 to 8 chopsticks
