PhotoScan by Google Photos, free for Android and iOS, is one option.

And Google’s PhotoScan turns your phone into a handheld scanner to make digitizing old hardcopy photos simple.

Now, you can use Google's PhotoScan app, which digitally scans your photos.

After taking 20–50 close-up photos of a pastry, Yu would transfer photos into the desktop photogrammetry app Agisoft PhotoScan to generate a 3D model of the food.

If you’re not looking for a high-end scan, though, use Google’s PhotoScan mobile app, which lets you use your phone’s camera like a scanner to capture photos, even if they’re framed and behind glass.
