What do you call it when...

[Graham_of_Rainham]

Set camera on tripod, swing through 120 degrees, stitch several images together = "Panorama"

BUT

What do you call it when... I take a series of images (lets say for arguments sake the front of Buckingham Palace) from a series of different positions, then stitch those together.

Has anyone tried this ? I've been looking for a good subject to try it out on, I think it will need to be a long building with no foreground detail.

So has anyone come up with a name for it, (other than a daft idea )

Hi Graham,

I did a search and found this, hope it's useful ... is this what you're talking about?

Multi perspective panoramic imaging
Panoramic images have only been feasible if all contributing image patches share a common center of projection. Then, they can be consolidated into a single image using perspective transforms. In contrast to that, we propose a novel non-linear warping scheme which allows the merging of multi-perspective images, thus taking advantage of scattered cameras. Therefore, a polygonal cut is defined in two source images to be merged. Usually, the layout of the cuts does not allow a user to stitch both images together naively. Thus, two convex combinations of a warped and a canonic coordinate system are applied so that both source images fit together at the cutting edge while the inevitable distortion decreases towards the borders of the image to obtain a natural appearance.

Sounds very complicated!

Complicated is a polite way of describing it...

My approach will be to simply take a number of images, perpendicular to the face of the building at regular intervals. This way the ends of the building will be the same size as the middle. In fixed point panoramas the the edns look smaller because they are further away.

I expect the end result to look like it has been taken from a very long way away with a big lens, that has flattened the perspective.

In a way it's a bit like a very slow version of slit photography, but done in descreet steps rather than continiously.

Thanks for doing the search, it was "interesting" up to the point where I didn't get it any more

Re: What do you call it when...

Good luck Graham I look forward to seeing the results. The one thing that fascinates me is that if you take a series of shots from different positions, how will they stitch together without appearing to bend?
