I'll try to make my answer almost as brief as your question. If it's not stored in the exif info, then.... This is done in forensics all the time. Look it up. You need to know something in the image, like known sizes of measurable objects (in the scene and on your sensor), and known distances in the scene, and/or known angles. Then it's just geometry and optics.
