[hugin-ptx] Re: Release 0.4 of pvQt pano viewer.

[Peter Gawthrop]

Hi Tom,
  
   I agree that "control of perspective" is THE important new
   dimension in photography and so I hope that pvQt can contribute to
   that.

   As I said in a previous mail to this group, the mathmap plugin to
   GIMP is another possibility for playing with perspective. I have a
   number of functions which transform equirectangulars (from hugin)
   in various ways -- see

   http://www.lightspacewater.net/Software/

   Maybe these are relevant to pvQt?

   Peter.

[winda551]

Thanks for the info, will see what I can do with it ...

However, I don't understand everything that you guys say (overrun, rpm
build), but I guess google will help ...
Debugging? Don't know how to do it, but I did it exactly the way it is
described on wiki.

I have debug turned off and the binaries are stripped.

An rpm build (which I'm doing) will always add -O2, whereas by 
default enblend builds with -O3, maybe it is a simple as that?

[hugin-ptx] align_image_stack droplet version?

[Dan H]

I think it would be useful to have a droplet version of
align_image_stack.  Is there one available?

I use Hugin to align hand-held exposure bracketed images for import
into a tone mapping program. I think it would be more convenient to
just drag the images onto a droplet rather than firing up Hugin and
going through the control point,optimize, configure output routine to
create the aligned images. Also, I wonder if the "divide into grids"
option in align_image_stack might actually even do a better job of
aligning the images, since it seems that autopano sometimes selects
control points that are concentrated in a small area of the photo
instead of distributing the control points throughout the photo.

Let me apologize in advance if this question has already been
addressed or this is not the appropriate forum for posing this
query.

Thanks, Dan

Probably, but I have no idea if anyone is collecting the data at the 
moment.  Development of the lens database has moved to lensfun:

The easiest way is to simply stitch a panorama in hugin and read the 
optimised values from the 'Camera and Lens' tab.

Maybe related to the 'Image cache memory' preference setting?  If

[hugin-ptx] Some problems with hugin trying to make a panorama

[Rahula]

Hello,

First, I am French so please escuse me for my english. I can't make a
panorama with Hugin. Matchpoint, matchandshift and generatekeys don't
work and autopanosift make very weird choices of keypoints. The
problem is that these have to process like eighty photos of a big size
(2-3 Mo). Autostitch, however, gives me a quite good result but the
stiching seems very bad.
What I can do is giving the photos and the result of Autostich to help
you make better Hugin, because I have no time to figure out how to
solve the problem.

Sincerely
Rahula

[hugin-ptx] PTlens database updates?

[Davide Capodaglio]

Hi all, I have a Canon IXUS 850IS and I would like to use hugin and
fulla tools to correct my photos deformations.
However my camera is present in the official PTlens binary database,
but not in the public old one in text format used by fulla...
Is there any chance that latest cameras will be included in the open
database?
If not how can I determine my own distortion parameters by myself? Is
this possible?

Thanks
Davide

Yes there is.

One of the things I like best about DevalVR is that it can save the

Yes, and it may be feasible to some extent.  The OpenGL tecnology that

size frame buffers.  But screens can be pretty big nowadays, and you
can render to "off screen" frame buffers bigger than the physical

What really limits the potential quality of captured pvQt views is
interpolation artefacts of various kinds.  Some of these are very
evident near the poles of equirectangular and spherical images as
displayed by pvQt; but there is a more general limit due to the fact
that OpenGL texture images can't be very large (2 - 16).  If you are
going to stretch an image dramatically, and want the result to be

Hi George,

Celeste should work fine on TIFF files too, it uses VIGRA (like Hugin) to
load images so any file type you can load with Hugin should work. Smaller
files will take less time to process so this is probably why it takes so
long for you.

If you send me a couple of your TIFFs I'll have a look. It could be a case
of 'the wrong sort of clouds' though, though the training set I used was
pretty diverse.

Btw here's a how to:

Harry,

Thanks.

I tried those files you sent me  ... I clicked the "Run Celeste"
button in the Control Points panel and it work removing all cloudy-
points but one.

Those were small JPEGs and my images are large TIFFs could that be the
reason? Or do my skies have the wrong sort of clouds?

If Celeste is supposed to work on TIFFs I can try generating JPEGs for
my image set.

all the best

George

I sent you the celeste example set to your personal mail address. Please try
that sample set. There is a pto inside the zip. Please load the pto and
rerun celeste. Please try again.
If it doesn't work we have a problem.

This was also mentioned in a mail on 27 October by  etherflyer (Black (and
white) lines in regular (non-HDR) files). He/She mentioned the same flaw
that happens occaisonally. So I think we need to register a bug report for
this one.

I re-stitched one of the panoramas at 10,000 x 5,000 and there was no
line.
I guess I will try 11,000 x 5,500 next time I am going to be away from
the computer for 4 or 5 hours.

[hugin-ptx] Re: hugin0.8_svn3562_20081111 for download

Harry,

Thanks for this.

I have tried it on a couple of panoramas recently and have found two
odd results.

1. First of all Celeste - does nothing
I have tried Celeste on both panoramas - they were both shot outdoors
in the North West of Ireland so by definition there were plenty of
clouds!
I tried it on the Images tab, selecting groups of images, including
selecting all and I have tried it on individual pairs of images on the
Control Points tab.  In all cases I got a progress bar (and a long
wait  in the case of selecting all)  - then a pop-up saying:
   "0 control points removed" (or words to that effect)
The pop-up told the truth no control points had been removed.
I then went through the control points panel and removed lots of sky
points (both blue and cloudy) by hand.

Have I missed some preference setting?
(I haven't read any documentation on Celeste  - I just noticed the
button and gave it a click to see what would happen.  So feel free to
tell me to go and RTFM.)

2.  Secondly a weird flaw in the resulting image.
Twice when I have stitched large equirectangular images (12,000 x
6.000) there has been a one pixel horizontal black line right across
the final image about half way down (at 2,800 in one case and 2,928
in the other).  Both were set to produce a stitched image 6,000 tall.
The line is not on any of the component "exposure-layer" images nor on
the composite "exposure" image - only on the "fused" composite.

One of those is re-running at the moment at 10,000x5,000 to see if the
line appears. When that finishes  I will try the 12,000 x 6,000 stitch
with an older version.
___
In each case I was using 0.8 3562 to stitch:
   24 files  -   8 x 16mm fisheye images.  (6 around + Zenith + nadir)
x  3  bracketed exposures (-2, 0 +2)
I generated control points with Auto-pano-SIFT-C, Cropped, Optimised
Control points and stitched at various sizes with the options below
(only the largest size had the line)
- Blended Panorama (enfuse)
- Blended Exposure
- Remapped Images
Options:
Nona:   Poly(Bicubic)
Enblend:   "-v  --fine-mask"
Enfuse:   none
In all cases I was using a PowerMac G5 running Mac OS X 10.4.11


all the best

George
