Existing methods to Automating Sculpting/3d Modeling Objects

Hello. I have an idea floating around in my head for a program that makes a 3d model from a given model turnaround image. My Question is does this already exist either in commercial or open-source form? Is there software out there that makes a 3d model or sculpts a model given limited perspective images? This does not have to be strictly for art.

 Also, although not as important, since this is related to 3d scanners, what options do you know exist for 3d scanning as well? I want to examine all related current methods to help better formulate my own.

Thanks in advance.

Just google for 3d scanning software or 3d from photos for other alternatives
