HowTo? Make pano wider that 360 degrees FOV?

[l_d_allan]

I'd like to make a pano that ends up having about 500 degrees FOV. Can this be done?

 

To illustrate, suppose I take pictures 0 thru 5 on a 14mm uwa. I'd like to duplicate images 0, 1, and 2 and then "place" them so they would in effect be images 6, 7, and 8 on the "right side" of image 5 after stitching is done.

0 1 2 3 4 5 + 6 7 8

 

I've tried putting the Pano Editor into "Edit Individual Images" mode, and dragging images. but that doesn't accomplish anything.

 

So far, PtGui overlays 6, 7, and 8 on top of 0, 1, and 2 so that the FOV remains 360 degrees.

I tried increasing the pano property to 400+ degrees FOV, but got a message about "this projection doesn't allow over 360 degrees FOV".

 

Could this work with a different projection? I'm using Cylindrical.

Hi Lynn,

The world around you has only 360 degrees. If you rotate the camera 370
degrees it will point in the same direction as when you would have
rotated it by 10 degrees. This is the way PTGui sees the world, and
therefore the output in PTGui is limited to 360 degrees (any wider would
just copy pixels from the left to the right of the panorama).

Hi Lynn,

I am guessing, but are you saying that you want to produce a flat image for printing or putting on screen rather than viewing in a 360 viewer?

If so, then you would just produce the normal 360 panoramic cylinder in PTGui then, outside of PTGui, duplicate it and join them next to each-other in, for example, Photoshop.

Otherwise, PTGui will just take any duplicate images and merge them together during any stitching process.

I hope that this helps,

It is possible to achieve, there was - can't find it at the moment - an image of the Tour de France that allowed you to rotate 3 or 4 times, each loop showed a different cyclist passing the the finish line.  Not sure what software was used to create it or if it used a non-standard viewer but I think it was a QTVR.

A classical similar classical example:

It's a "true" cylindrical QTVR panorama

yes, in your image editor. Simply create a 360� view, then duplicate it
and copy it to either side. In Photoshop you would duplicate the
background as a layer, then enlarge the canvas to one side to 200%, then
shift the layer with it's previous width to the right using
Filter->Other->Offset. This way you get a seamless image of 720�.

I didn't find it yesterday, but here is an example of an interactive
day-and-night panorama made this way. You can go two rounds until you
are at the same time and place again:

You'd have to make 720 degrees, or some other multiple of 360, to be able
to view it seamlessly in a panorama viewer, I guess. The problem would be
to get a standard viewer to display it without compressing it sideways.
It would be much easier to make a pano with more than 180 degrees vertical.
