FireNet is absolutely right. I don't know of any tool that can automatically take a 2D image, no matter how detailed, and turn it into a 3D render-able object. There's just not enough data in the 2D image. There are tools available to make it easier to MANUALLY do the job, some free, some really expensive.

I'm in the process of trying to learn Blender, one of the better free options out there. That would be a great place to start, if you're not already familiar with it.

Good luck!
