The food scans are just photos from a Pixel phone processed with postshot (https://www.jawset.com/) to generate the splats
Out of interest, to what extent do splats recorded in this manner have reliable/measurable dimensions?
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.
Yes there are several phone apps to generate splats. Also Luma 3D capture.
