Abstract: The term *photogrammetry* typically refers to the process of constructing a 3D model by analyzing a series of photographs of the same subject captured from various angles. Widely employed in fields such as mapping, surveying, architecture, archaeology, and cultural heritage preservation, photogrammetry is very expensive computationally and is traditionally done with commercial packages, even on large workstations and HPC clusters. Regrettably, in the eyes of many academic researchers, open-source photogrammetry tools have still not caught up with proprietary software in terms of both performance and output quality. Even further, running open-source photogrammetry on HPC clusters is far from trivial.

In this webinar, we'll demonstrate a couple of photogrammetry workflows that we have run successfully on Cedar. We'll take a look at OpenDroneMap and few other tools and will discuss all steps from taking initial images to building and displaying a final 3D textured model.
