360 Spherical Pano Naider Patching.

[James Denise]

I am trying to figure out the easiest way to patch in a clean Nader point using PTGui 9.1 all the info I have found relates to older versions that have an option to extract the Nader image (usually my tripod) clean it up and then stitch it back into the 360 sphere.

I own a copy of Pano2VR if that would help as well. It does allow you to patch in a cleaned up image but I need to be able to upload the full 360 spherical that has not been broke down into the squar that this software uses.

Any insights would be appreciated.

Attached is a copy of a 360 spherical I am working on now.

Well I see no one has had an answer to this but I still would like it addressed as I have not found a good solution yet. I am a registered user of PTGUI Pro V 9.17

Hi Jim,

There is a few ways to patch the nadir. Here is how I do it. 

I always stitch my image in PTGui and export the panorama as an equirectangular image. I then import it into Pano2VR and create a patch for the nadir. I then open it in Photoshop to overlay the image I took to patch the nadir and reimport it into Pano2VR. If I want to get a unique file I then Convert Input from Pano2VR as an equirectangular file. Do not forget to apply all patches. I then have a full 180° x 360° image which could be imported in Panotour Pro, Pano2VR or whatever tour builder you prefer.

This might be because you didn't provide enough info. Do you have a
nadir shot or do you need to retouch it? If you have a nadir shot was it
taken from the same viewpoint or sideways? If you ask for future
panoramas it depends on whether the floor is flat or not.

The easiest possibility is a flat floor. Then you can simply move your
tripod sideways and shoot the area it stood before from there. Then use
viewpoint correction: http://www.ptgui.com/examples/vptutorial.html

For all other possibilities use the PTGui page or
http://wiki.panotools.org/Zenith_and_Nadir_editing_overview
as a starting point.

Thanks for the input. This may be the solution I am looking for. I will try it out later or tomorrow as I have company coming over in a while.

Sorry I didn't post enought data. I do not have a separate shot of the nadir But I was not sure how exactly to do it without a perspective change. If I wanted to shoot a separate nadir shot by flipping the camera down I would have to move the tripod. Would that be an issue or is that standard. I'm new to 360 Sphericals and want to learn best practices.

Thank you both. I'll check back and post my results and check for other inputs.

Sincerely
Jim

Since you have Pano2VR, the simplest solution is to load in your equirectangular panorama image and run Convert Input to generate 6 cube faces.  Edit the nadir face.  Avoid changing the edges of the image so that it can be merged seamlessly with the other faces. Then load in the 6 edited cube faces and convert to equirectangular. NB. Visit File->Settings->Images and select the Interpolation Filter to Lanczos3 for best quality.  There is an edit feature provided in Pano2VR, but it can be a little confusing.  There's a video tutorial on their web site.

If the floor is flat you can use viewpoint correction (see last
message). If it's not flat you need to shoot straight down from the same
point you shot the rest of the panorama. Since it isn't possible to do
that by hand precisely it's probably easier to retouch in photoshop.

I use Nodal Ninja (NN5 or M1L)with the Nadir Adaptor. I put a marker
directly under the center column of my tripod. With my fisheye, I shoot 6
around then at the starting/ending point of the around shots I point my
camera straight down shooting the axis point of my tripod. I then, by use
of the nadir adaptor, rotate the camera 180 degrees, then move the tripod in
the direction from which the camera rotated and get my ground marker
centered in the viewfinder and then shoot the nadir patch.

I am finding this thread of advice on nadir patching very helpful. After years in which I solved all nadir problems using the Super-rune plugin for PhotoShop, I am finding it impossible to use in Windows 8 with PS CS6.

Superrune doesn't work with 64-bit Photoshop. Only 32.

If it happens that you have by chance a license of KRpano  then you  can download the KR tools which contains 2 droplets which are transforming an equirectangular to 6 cube faces  and the other  brings 6 cube faces back to an equirectangular. It couldn't   be more convenient.

Thanks, but that isn't my problem...

Thanks, Willy, that's worth knowing. Unfortunately I don't have KRPano.

Roger,

I don't have Windows 8. But a while a go I started to update the panotools plugins for 64bit. This may solve your problems. The main parts work but I never finished because I find I use PTGui and viewpoint to solve 99% of my nadir patching problems.

Unzip this file and copy the Panorama Tools folder to your 64bit plugin folder, by default here.
C:\Program Files\Adobe\Adobe Photoshop CS6 (64 Bit)\Plug-ins\Filters

Thank you, Jim. It is many years since I played with the PanoTools plugin, and in fact I now have two work-arounds that help me cope with nadir holes. One is to ignore the error messages I get with 32-bit CS5 and continue to use Super-rune. "Retry" lets me proceed. The other is to use Erik's templates within PTgui and edit the nadir face in 64-bit CS6 using the not-awful context-aware fill. After a bit of practice I now find it as good as careful cloning--and much quicker/simpler. Both involve leaving PTgui for PS but currently I am using this opportunity to learn more about templates, something I ignored until this problem. I found the Pano2VR approach less simple, though I was able to make it work.

But when I have a flat floor, I find as you do that the viewpoint function does the trick. I guess I could also try to reposition my tripod more accurately using the Nodal Ninja hinged thingy, and use a remote to get out of the way. Lots of different ways of filling the hole. And now another! I will download and try it as soon as I get back to my PC. Thanks again. If I can't figure out how to do the necessary transformations I'll ask you.The older I get, the better my forgettery (wry grin).

Thanks for the great inputs. The info on using Pano2VR and converting after patched is just the help I needed for this project and was easy to do for me. I'll try some of the other info here as well so thanks to all for the inputs. It was great of you to help out a fellow photographer.
