This panorama is of a camera calibration grid that I use for photogrammetry. I captured the panorama to explore the level of error that exists in a panorama and to evaluate how much of that error can be removed via image manipulations in GIS. This is just a quick initial test. I will generate additional runs at controlled distances between the camera and the subject.

    Do you ever use multiple EOS 1 meter targets to cover the area you are trying to measure or do you just photograph it at the same distance with the same camera and lens?

    If you are able to carry a Panasonic Lumix and a Canon EOS macro lens you can further minimize geometrical distortion. There is an adapter that will allow you to use Canon EOS lenses with a Panasonic Lumix. Another low mass solution would be an Olympus 4/3 with a macro lens. Macro lenses are designed to correct geometric distortions better than regular lenses.
