Cube to equirectangular

[Brandon]

In my work flow I take an equirectangular, make it into a cube to edit the floor and sometimes the sky then use it as is in a Virtural tour. I now have a project where I to put the cubes back into an equirectangular image.

I know that Bruno Postle has cubic2erect, which sounds like it does what I want. I have never gotten along with pearl though so I am not able to use it as it. Instead I have done the same thing near as I can tell in hugin. I loaded my 6 images, set them at the correct locations and then checked the preview, it looks amazing. I think perfect this is simple. Then I go to stitch it and then I see, it is not so simple as it messes up.

I have stiched a few times, it always claims to have worked. The results are always a bit wonky though. The pictures it warps to make the final pano look good. If I wanted to I could put them together with photoshop or the like. When enblend gets the images it messes them up. Where they come together it tries to blend them and it makes a mess. It seems like there should be a command line option that I could give enblend to not do that. Or maybe I am doing it all wrong and there is another better approach. 


Bruno's script is here http://cpansearch.perl.org/src/BPOSTLE/Panotools-Script-0.28/bin/cubic2erect
I have attached my project file and two example images showing the problem. The only diffence between them is that one is 100 pixels wider which made for a very different blend line.

Hi Brandon,

if you use multiblend instead of enblend with hugin it will work perfetcly. At least I have done it in the past.

On the other hand we could help you installing perl and the Bruno's cpan module. What platform do you use? Win? Mac? Linux?

Bests,

You don't need enblend to assemble cubefaces (though I'm sure this used to work ok).

So long as you are happy using the command-line, nona will stitch a Hugin .pto project in one go without blending seams:

nona -m TIFF -o output project.pto

Hmmm, nice to know that! I thought it would generate the individual remapped images.

I see only now that when not using '-m' the default into the pto file is TIFF_m (multiple tiff).

Tks,

Thanks Bruno,

That solves my problem. Now I make a batch file and it will just happen :)
