fine-aligning already coarsely/almost aligned images?

[jean]

Hi all, 

I'm trying to use a robotic head to shot my pictures for a 360*180 panorama.

If i could manage to set angles and stuff by hand in Hugin once, then save them as a template project and reuse it over and over without further computations, it would be awesome.

Anyway, despite the proven accuracy of the head, i often need to fine tune some image (maybe the wind or a clumsy move shakes the whole tripod sometimes...)

Fact is, in interiors or scenes with wide skies, some shots completely lack reference points, so there is no point in running them through the feature detection/parameters optimization treatment.

Is there any way to tell the optimizer to do its stuff but never get too far from the originally setted parameters? Some way to tell him "this is more or less the direction of the shot, now do your best"??

A simple way to do this is to make a hugin pto file and always repeat the image names. Your job would be renaming the image files every time. Depending on your operational system and skills it could be easy to make a script to do that. Another script could make the pto file using the different image names based on a template. I bet all this can be done using python on hugin.

As long as I have read here, cpfind will consider the pre-aligned images when trying to find the control points, so, if you use that template and there isn't really good control points between some images, they will be left without them and will not be repositioned if they have no control point.

If you can't do a script or think it would take you too much time you can test with a hand made template. I have never tested those things, so there can be something wrong or missing in what I am suggesting.

You can do this with 'Apply Template' from the file menu - just select the new images corresponding to the ones in the template .pto - you don't need to do any file renaming.

Not really. An image which has no control points might be left more or
less alone, but it will be as if it is not connected to anything. The
slightest hint might make it move away from where you placed it.

What I'd like to have is that I define two controlpoints against the
"globe" for each image, so that real controlpoints can easily pull
things in the right direction, but that images with no control points
will at least stay put.

I think I've submitted a feature request into the bugtracker for this.

Check it out and register the fact that you'd like to have this too.

Roger.
