There's a community of people passionate about scanning all short stuff with handheld devices, drones... Tipatat let us generously use his food scans for the demo. I also enjoy kotohibi flower scans: https://superspl.at/user?id=kotohibi
Edit: typos
The food scans are just photos from a Pixel phone processed with postshot (https://www.jawset.com/) to generate the splats
They are not reliable at all unless paired with some physical measurements (Lidar, or a known size object in the scene).
Probably an interesting use for a pretrained model to estimate scale based on common items seen in scenes (cars, doorframes, trees, etc…)
I'm sure it's not cutting edge, but the app "scaniverse" generates some very nice splats just by you waving your phone around an object for a minute or so.
Wow what kind of device do I need to make my own?
