Finding real world distance using an image

I am working on a project where I need to figure out real world distance of an object with reference to a fixed point using an image.

I have detected the object in a 2D image, using SURF. My object is inside a box now. What will give me the position of the centroid of the object. How can I use this to find out the real word distance?

If I plan to incorporate stereo vision, triangulating the centroid of the object, what is the difference between the distance I obtain here and in the previous method?

On a single image, probably the best starting point to learn about estimating metrical properties is Antonio Criminisi's work (2000 vintage, but still very relevant): http://www.cs.illinois.edu/~dhoiem/courses/vision_spring10/sources/criminisi00.pdf
