There are tons of 3d scanners, including ones that can live on your phone (I think Autodesk made one), up to professional grade ones with a turntable and cameras. They spit out an STL that can be imported into Blender and used for whatever purpose you like. I think practically this sort of thing is not that useful -- it's easier to iterate on 3d models in a 3d editor (especially since for animation purposes you need to have a parameterized model) rather than trying to get something from a real object.
