If you have Photoshop or CAD you can, depending upon the structures in the image, get some rough perspective lines to help close in on 'rough dimensions'. Generally finding vanish points is very helpful albeit frustrating and usally requiring lens (distortion) Corrections.
You can export the image with the perspective lines as the BG image in max and change camera settings and position to match the perspective grid/s.
Suggest doing what you can for the camera match and work very hard to make the lighting, GI ect "marry" the CG to the Image.
Personally have not really used or seen any application that works stupid well. Image Modeler is/was good at camera matching, however you need multiple views to make it work. Basically a static version of Match Mover, created by the same company as Image Modeler
Good Luck
