Is there sourcecode somewhere so porting (except for using Wine) would

In the preview windows the result looks like a circle, where each side
is around 45 degrees from the right, left centre rotated. If you want I
can make a screenie, but it is really obscure.

Around 280 degrees.

8 for the 360, and 1 (fisheye) for the top.

The photo's are available, but sadly there is a tiny problem with the
white balance, so they are not yet equal. If you want to give it a shot,
I can post them somewhere.

[hugin-ptx] 360 panorama's

2010-07-11 Thread Stefan de Konink
-BEGIN PGP SIGNED MESSAGE-
Hash: SHA512

Hi,


I was able to compile the lastest sources. I have a strange issue; I
have 8 images, from an aligned camera setting. Sadly Hugin gets heavily
frustrated if I have keypoints that matches the beginning and the end of
the image. Is there a way to actually have Hugin panorama 'enabled'?

When I remove the keypoints between an image pair so that I have just a
wide view, I select cylindrical. From that I see that the alignment in
the preview (and afterwards) is not actually transforming the image:






Does anyone have a good tip how to make a template for this camera? Next
to that, is there a way to make Hugin or enfuse to equalize whitebalance?


Thanks!

Stefan

Hi,


Maybe you all remember Bundler[1] that was pretty nifty. I just stumbled
again on PMVS2[2] they have released their software now under the GPL.

I wouldn't suggest all start to download it from the source, since it is
315MB large. Therefore for the Europeans I have mirrored it to the Dutch
OpenStreetMap mirror[3]. Also in 'source only version'.

This kind of software and academic research really opens up 3D
reconstruction from images; but usually this is PhD-ware, this means
that the crowd could really make it better or improve it in speed.

Likewise here. But still if one blow of wind can take a quad copter
about 2 meters down. That *does* matter, optically.

Next to just adding them to Hugin and per photo stitching we don't have it.


But I saw your last email and I wonder:

 How did you solve the altitude difference? Because we have many
 problems with that. If in one flight different altitudes were flown
 hugin really can't stitch it.

We did; we have a rectifying program, and like I posted before I was

final positioning. Come and idle in #osp on oftc ;)

That doesn't limit the community to get in contact? When I saw the
youtube video's I think this is a great addition to what people can do
with Hugin.

My firefox doesn't have problems with the above :)

But it seems their code is on sourceforge:

Hi All,


One of the Leica users pointed me at the following site:

http://www.efoto.eng.uerj.br/doku.php?id=en:start


And I think that if you like Hugin, you might wanna add that one also to
your toolchain :)

Where I can find the other line type? I see normal, vertical and horizontal.

Thanks for mentioning this. I have applied this patch to trunk (with the
minor update to the rejection) now strugling with cmake and WxWidgets. I
see on sourceforge there is actually a comment about improving your patch.

If you improve it, imho you can apply :)

I have experienced the same regarding to the the keypoint selection
window when going fullscreen I have lost the images. Sadly bad reproducable.

Also a segmentation fault in the latest version when pressing optimise.
Couldn't reproduce that consistently too. So I'm now running in GDB to
see if I can find it.

[hugin-ptx] I would like to have some features, and I have money for it.

2009-08-23 Thread Stefan de Konink

Hi,


I know this e-mail has been send to you all way too late, I kind of
refuse not to send it. I'm in a project that has a money grant till 28
August. I would like to place some bounties for talks that must be
finished before them. It is an one time offer, you don't have to take
it :)

Rules of the game:
 - its a bounty, feature must not exist already in development trunk
or stable version.
 - transaction MUST be completed before 28 of August.
 - I would require an IBAN+BIC number to transfer it to your
bankaccount.
 - It would be nice to get the features into Hugin, I can understand
that 4 days to polish code is too short,
   but at least make it in such a way that it can get into inclusion
shape.
 - That also means license it in such a way it can be included.
 - Please announce you are working on a thing, I don't want do do
first come first serve stuff.
 - If all items are taken, I can easily provide some other things that
could be useful aswel.


Features that I would really want from usability perspective:
- Show the horizontal and vertical lines that are drawn between to
matching photos inside the viewer - 25 euro
- Show the keypoints in the example window - 25 euro
- Share user entered controllpoints between images - 25 euro


Features that I really need for correcting aerial imagery:
- Improve the correction for near and far imagery example:
http://blog.opengeo.nl/uploads/2009/08/temppano.jpg - 50 euro
- Allow controlpoints to be entered in global 2D parameters, aka the
ability to click and type a GPS point - 50 euro
- Additional provide these coordinates in the example view when moving
the mouse - 25 euro
- Additional provide a world file export (or GeoTiff) with the corner
coordinates - 25 euro


Features that I know other people want:
- Do true image rectification within Hugin; 
http://en.wikipedia.org/wiki/Homography
100 euro - (OpenCV code is available from my side)
- Create control *lines* between two imagines, for example if a
straight road is available but the photo's are non-overlapping or
difficult to enter features on. Automatically find lines
(Houghtransform)  or manually enter lines (like horizontal/vertical
now) that can be used as parameters to move a photo along and/or
transform the image for placement. - 150 euro



This will be funded by the Dutch registered non-profit foundation
Stichting OpenGeo, which has a grant via the Digital Pioneers for the
OpenStreetPhoto project. If you have questions you know my e-mail
adres now, questions regarding the tasks or pointing me at 'all ready
there' can be done by the mailinglist.

I want to strongy point out that I am really limited to the deadline,
and I wish someone else already had picked this up in the beginning of
the month.

Treasurer of Stichting OpenGeo
