If this is another aspect about your 3-D chess game then I think you are aiming for way-to-much and you really need to narrow the scope of what you can achieve in the next 2 weeks.
Images can be used to texture (read put colour onto) a 3-D surface, but they bare little relationship to a 3-D model which is what I suspect you are really asking about.
I believe it would be a very difficult computer science problem to solve to be able to extract a 3-D model from a 2-D image (and make it look good). I am not aware of any such engines that you are asking about.
However, to offer some advice on getting to your goal, try searching the web for some free 3-D models of the images you are after. You never know, you could get lucky.
