TaylorAlexander on HNHow does this improve on taking a video with your phone and feeding it to one of the OpenSource 3D reconstruction packages (such as e.g. MeshRoom [1])? [1]…

OpenScan for small objects
From 1 comment
This is for scanning larger things (rooms, buildings). For smaller objects, there's another open-source project that you might find useful: openscan.eu

3D Live Scanner app on Android
From 1 comment
On Android if you have a powerful enough phone (or better, built in Lidar) then the "3D Live Scanner" app by Lubos Vonasek Programmierung is something to checkout.
