| Hi Claudio and Cartola:
Wow! I don’t know whether to be happy or sad. I’ve just spent two full days trying to do what Claudio just sent me. I’m happy — very happy — to see that image, but sad because I just don’t know how to do that. Cartloa’s panorama is beautiful but so far beyond what I can do that I’m at a loss for words.
I will try again tomorrow using what you told me to see if I can make progress.
Thank you and muito obrigado!
Aloha, The images you posted stitch just fine thus far. Keep in mind that every time you move the camera and place it in a different position (displacement, not rotation) you will be dealing with parallax so there will have to be some creative masking involved.
A few ideas. Create control points by rows and columns. I've never trusted multirow to work automatically, so what I do is create the control points by selecting only the images that I know have common information: for example select 0_1 and 0_2 and press "create control points"". Repeat for images 0_2 and 0_3, then 0_3 and 0_4. Then move to selecting 0_1 and 30_1 and finding common control points. Then in the Optimize->Geometric select "custom parameters. A new tab labeled "Optimizer" should appear on the top window.
In the Geometric optimizer window select all the paramaters for image orientation and hit optimize now.
Choosing the "correct" projection might be tricky once you add more images.

You are trying to do what is called a Flying Willy panorama. I did one once from the top of a building. It took me a lot of post editing to make the panorama look without joining defects. The taller the building and the most far the objects, the easier it will be. Your situation is in a city, where wrong stitching will surely appear. I thing it won't be possible without too much editing.
Take a look at mine:
At the end the building below vanishes, as if it was the tripod.
Since I cannot stop thinking about this, I thought I would share with you all my current thinking.
I will first stitch together the four images from 0 degrees to create a sub-panorama, called 0-degrees. Those four images will all have been taken from the same location so Hugin should have an easy job finding control points. After doing this for all 12 azimuths, I’ll have 12 sub-pans: 0-degrees, 30-degrees, 60-degrees, …, 330-degrees. Then I’ll stitch these pans together three at a time: 330-degrees, 0-degrees, and 30-degrees; 60-degrees, 90-degrees, and 120-degrees; 150-degrees, 180-degrees, and 210-degrees; and 240-degrees, 270-degrees, and 300-degrees, to create four sub-panoramas: north, east, south, and west. Then I’ll stitch these four together to create the final desired panorama.
Any thoughts on this approach? Gentle People:
I want to create a panorama to use with SkySafari. The goal is to reproduce the view from the roof of my 400' condominium in Honolulu. I cannot take a panorama with a tripod from the center of the roof since there's a large air conditioning structure on the roof. So I thought I would take pictures from 12 different spots around the roof at 0 degrees azimuth, 30 degrees azimuth, 60 degrees azimuth, etc. The final panorama has to have a transparent sky and extend down to the nadir. I took a similar panorama 12 years ago but from a fixed position. I'll attach that pan for reference.
Yesterday I took four shots from 0 degrees azimuth, four shots from 30 degrees azimuth, etc. I cannot use a tripod because there's a four foot high and three feet wide wall all the way around so these are hand-held. I'll attach eight of them for reference. I need to stitch together all 48 of these photos, but I don't know if Hugin can do that. I'm hoping someone can give me some advice. This is obviously too big to email so I assume those who want to see the images can look at the link.
Please tell me if Hugin can do this!
Thanks and Aloha,
Sam Rhoads Honolulu
