Apply the photo to a ground plane and use orthographic camera above that
while placing objects into the scene.

plane {y,0
    pigment {
        image_map {sys "YourPhoto.bmp" once} // whatever photo format
    translate -.5 // center
    scale <YourPhotoScaleX,YourPhotoScaleY,1>
    rotate 90*x
                }
}

camera {orthographic
    location -100*z // place farther than largest object extent
    right YourPhotoScaleX
    up YourPhotoScaleY
    look_at 0
 rotate 90*x // comment out to see from front instead of above
}

Maybe that will be of some help to you.  Not sure how your using your DXF
(as a mesh I suppose).
