I'm trying to match up the perspective of a camera to a background image. The purpose is to render furniture to composite into the image. Does anyone know of a good way to line up the plane so it the same perspective as the floor? I've already set the blender camera to be the same focal length. I know if I mess with the position and angle long enough I will get it but any ideas on how to speed up the process up would be much appreciated.

-Thanks

perspective image match example

Blender File if you'd like to try it yourself

The reason you're having trouble is that your photo camera wasn't straight. I can tell because the far corner isn't perfectly vertical. It's VERY easy to fix this particular image:

  1. go to the Camera view
  2. Hit 'R' (Rotate)
  3. Type -4.2

Pretty darn close when you move it back to the corner. You can tweak it a little either direction to make it more exact. Caveat is that I had to guess a bit because that gray floor was in the way since I just downloaded your example image.
