In this video, I explain in way too many minutes what exactly photogrammetry is, what it is used for, and how to do it with the DJI Mini 3 Pro.

I show a detailed example of manual capture at the Saissac Castle ruin, in the south of France.

I then give an example of how to process the captured images using two different softwares : 3DF Zephyr, which is a commercial software, and Meshroom, which is free and open-source. Note that a free demo version of 3DF Zephyr exists but limits you to 50 photos, if you want to try it out for yourself.
