Hello and welcome everbody!
I recently stumbled across a free and open source photogrammetry tool called Meshroom. In this video I will give you a first look of the program and what sort of results you can achieve with it (spoiler: It produces super clean meshes.). Meshroom hasn't been released yet, but if you go to their github page, you can see that a first release is just about to happen within the next few weeks.
So get excited and join me exploring Meshroom!
