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. 00:00 Intro 01:23 What is photogrammetry ? 02:09 What is photogrammetry good for ? 03:18 How to do photogrammetry ? 07:12 Recap of good practices 07:42 Practical example 17:49 Processing with 3DF Zephyr 28:47 Processing with Meshroom 32:12 Results comparison Music credits 🎵 The Bonfire - Blue Steel 🎵 Let There Be Rain - Silver Maple
