hello everybody,
My question is about stitching panorama of drawing on antique vessel. I have an experience with 360┬░exterior/interior VR tours.
No 1 - how to shoot, how many overlaps, any advice about lenses etc.
No 2 - how to proceed with Autopano Pro, my version is 4.2.
Thank you very much, every idea will be appreciated.

It seems that your problem is similar to this
viewtopic.php?f=2&t=37653
viewtopic.php?f=2&t=31717#p182669

You can try these settings
viewtopic.php?f=2&t=31164#p181055

As for the overlap, the usual, between 20 and 30% should be adequate.

Hi Panoram1x,
Thank you very much! I will try it. I used PtGui, better results but not enough. An example is attached below. A drawing is curved horisontaly and a little vertically. :)))

You will let us know how this has worked for you.
... remember that the camera can only be moved up / down and right / left, but can not be tilted and must maintain a constant distance from the drawing with the optical axis perpendicular to it.

Hello,

Can you give more details about the hardware used, the way you shoot, etc?
What camera/lens couple
Aperture
Did you shoot using a kind of grid (rows and columns)?
Did you shoot from a single point or multiple points?
How many pictures?

Thanks in advance.

Best,
Olivier

Hello,
Many thanks to all that took part of my post. A scene on the vessel contains 4 figures/persons about 5 cm tall. The whole scene is about 8 cm long, curved around the vessel. My camera Canon 5d mk II with Canon 100 mm Macro lens is positioned in front of scene a little bit down to the axis of vertical curve. I shoot vertical several images of each figure/person with different focus and stitch them to obtain multifocus image. Finally I have four multifocus images to stitch in panorama. The camera is immobile and I turn the vessel to have each part in front of the lens. I obtained an acceptable result with Image Composite Editor of Microsoft. Some fragments need to be adjusted by free transform in Photoshop.
Thank you very much to participate in this problem. Every idea will be appreciated! :-)

Hi... I am still lost in what you are trying to achieve.

Are you after a high rez extracted image or a multi row 360 like this...

I think before I had not understood what you want to do
If what is needed is to obtain a development (flat image) of the outside of the vessel, it is possible that your case is similar to this other viewtopic.php?f=7&t=33537
If so, you can try the procedure that I've used to obtain the development of the bark of the tree [Improving my vertical misalignment :) ]
In your case it is not a cylindrical object and I do not know if the conical vessel will create insurmountable problems.
But if you shoot the photos from further away and use a long focal lens, the flattening effect of the telephoto lens will minimize the problems of misalignment between the upper and lower part of the vessel (I hope)

Yes, thank you very much Panoram1x. "the development of the bark of the tree" is my task. I made several series with 50 mm focal lens, 70 mm focal lens, etc. The best results, as you mentioned, are with 100 mm macro.
