Shape from motion or shape from silhouette?

edit

Hi everyone,

I would like to make an application where I can make a 3D model out of an object and make measurements on that object. I have done quite a lot of research on both shape from motion and shape from silhouette. However I am not sure which way I should go. Which would be cumbersome after a while, and which would be the most effective? Also if you know some great implementations for these methods, I would appreciate that too.

Thanks for your help in advance!
