This might already exist depending on your exact requirements and it's a fairly common technology in the world of metrology. I regularly work with manufacturers to reverse engineer and/or measure molds, jigs, and fixtures for which there are no drawings available. A ROMER or FARO arm with a laser scanning head outputting its point cloud to a software like the PolyWorks suite can generate an incredibly accurate CAD model of incredibly large parts in a very short amount of time (an hour or two at worst if the mesh needs a lot of cleanup).
I assume that process would be easy to speed up if the requirement for absolute accuracy was removed. The 8' ROMER arm we use is accurate to ~!2 microns over its entire volume which is absolutely overkill for something intended to produce models for visual arts applications. A quick and dirty approach to generating the mesh might increase the inaccuracy by several orders of magnitude but when coke can has dimensional tolerances to the tune of tenths of a millimeter, the quick and dirty mesh will still be representative of the end product.
