Between January 9th and 18th, the Create Caribbean first-year interns engaged in a four-day digital photogrammetry workshop facilitated by Jonathan Rodriguez, a Fulbright Scholar from the University of South Florida. Photogrammetry is the process of creating 3D digital models of real objects using overlapping photos taken from all around the item. We were able to actively partake in the process from start to finish.
On the first day, we received an introduction to the concepts of digital photogrammetry, understanding its functionality and real-world applications. Afterwards, we relocated outdoors to capture images of a few small objects we brought and historic pottery pieces sourced from the Cabrits National Park. While outdoors, we were exposed to various elements -like the wind and sun- which allowed us to gain a sense of what it would be like to work in the field on a typical day.
Commencing day 2, we began the model development phase with the use of Agisoft Metashape software. We imported the photographs captured on day 1, learned how to convert them to the necessary format, and proceeded through the steps of constructing a mesh, performing cleaning procedures, building textures, and more.
Beyond that, we brought in larger objects and took photos of them outdoors. By this time we were getting more comfortable using the camera.
Come day 3 we had begun the process of generating digital models using the photos taken from the previous week. Each intern was able to walk through the entire process at least once, from capturing photos to exporting a final model. By developing multiple models, we were able to familiarize ourselves with the software and the steps to developing a full product. We all found the cleaning of models to be quite therapeutic and favoured this process over all.
On the final day, we were presented with metadata logs which we were to fill out. Metadata is used to summarize basic information about data that can make tracking and working with specific data easier. Afterwards, we took turns capturing photos using the turn table and camera. This proved to be much easier than manually moving around the object with the camera.
