Yann Lanthony dives deep into the open source photogrammetry (3D 'photoscanning') software Meshroom in this tutorial.
In this tutorial, we will explain how to use Meshroom to automatically create 3D models from a set of photographs. After specifying system requirements and installation, we will begin with some advice on image acquisition for photogrammetry. We will then give an overview of Meshroom UI and cover the basics by creating a project and starting the 3D reconstruction process. After that, we will see how the resulting mesh can be post-processed directly within Meshroom by applying an automatic decimation operation, and go on to learn how to retexture a modified mesh. We will sum up by showing how to use all this to work iteratively in Meshroom.
Finally, we will give some tips about uploading your 3D models to Sketchfab and conclude with useful links for further information.
