Re: [hugin-ptx] Hugin - Microscope images showing strong parallax when stitched
hercat The program automatically generates suitable control points when I tell it hercat to align. However, when I reach the fast panorama preview, the resulting hercat image shows strong parallax, and is much narrower on the right side, even hercat when I select Mosaic and Cylindrical projection. You have to use rectilinear projection. Don't ask me why or how, below is how I do this. Hugin works very well for stitching microscope images. No need for lens calibration in my experience. I follow the procedure for stitching flat scanned images at: http://hugin.sourceforge.net/tutorials/scans/en.shtml For examples, look at http://histoweb.co.za/ and http://gallery.chaos.co.za/index.php?/category/8 From my experiences, some notes: 1. The align function of the Assistant Tab sometimes work, sometimes not, so I do it by hand as explained in the tutorial. 2. It is not always necessary to do the New Lens step. Depending on your microscope and camera setup, this has already been set to different lenses or, does not make any difference. 3. On the Images tab, you can use the Create control points button. With multi-row captures, this is not always work 100%, but take care of most of it. 4. On the panorama preview screen, NEVER touch the Center button. 5. On the fast preview screen, stay away from the Move and Drag Tab. It is extremely easy to mess things up here. 6. One mayor hassle, and I should take invest some time and figure what I am doing wrong: On the Stitcher Tab, you have to click the Calculate field of view and Calculate optimal size button, and adjust Crop in the fast preview screen several times before it will give you the correct sized 1:1 output. 7. For large multi-row stitches, (for example http://histoweb.co.za/012/012img001.html) I find it useful to use the following steps: a. Load images and set HFOV(v) = 10 b. Stitcher tab select Projection = Rectilinear. c. Stitcher tab Field of view: Horisontal = 50 and Vertical = 50 d. Create control points. e. Do not do any alignment yet. f. Open the Preview Panorama window. g. Click None (Show none of the images). h. On the displayed images buttons, select the first two overlapping images. i. Go to the optimizer tab, and do custom optimize and described in the tutorial (Custom - r, v, d and e or Custom - r,X,Y,Z excluding anchor). Usually rvde works best. j. Accept results if low enough. k. Open the Preview Panorama window. l. Adjust the viewport. m. Add an additional image overlapping with the previous two images. n. Align again. Sometimes it is possible to add more than one image to the existing aligned set. Problems are usually encountered when you reach the end of the slide and go to the next row. Hope this help, and feel free to ask if you need more info.

Re: [hugin-ptx] Hugin 2012.0beta1 released
Hi Harry It seems that I was a bit premature with my patch. The api-min/max strings from the python scripts are compared to HUGIN_API_VERSION and this is defined as ${V_MAJOR}.${V_MINOR}.${V_PATCH}. So in order to actually work, the api-max would have to be set to 2012.0.0. Obviously, the same should apply to api-min. However, I don't like this. In my book, the patch version should not be api relevant as it should serve for bug fixing, which should not influence the API. Therefore, I propose the following: The current HUGIN_API_VERSION shall be redefined as #define HUGIN_API_VERSION ${V_MAJOR}.${V_MINOR} Unfortunately, this will influence the behavior of the warning message regarding the possibly changed preferences upon upgrades, too. If this is not desired, an additional #define HUGIN_FULL_VERSION ${V_MAJOR}.${V_MINOR}.${V_PATCH} could be defined and used instead. As an alternative, #define HUGIN_PYTHON_API_VERSION ${V_MAJOR}.${V_MINOR} could be used for the python interface checks only. Of course, at least the second solution is much more invasive and probably exceeds the amount of changes tolerated for a beta version. It could be applied to the trunk, though. I can supply you with patches for all options. I tend towards the HUGIN_PYTHON_API_VERSION, at least for the current release. What solution do you prefer?

[hugin-ptx] Re: Translators requested for Hugin 2012.0 release
Hi all, there is a first bug report about typos in the strings which should be translated. https://bugs.launchpad.net/hugin/+bug/1028387 Are there more typos? If you found one please report back. We will collect some typos and fix them in one rush to keep the annoyance for the translators as low as possible. Maybe also a native speaker could help us with some better words/ sentences for the proposals in the bug report.

[hugin-ptx] Garbage output despite many control points
Hello, I tried to stitch 30 photos to create a 360° equirectangular (and then stereographic) panorama following this tutorial: https://secure.flickr.com/photos/jftphotography/505008136/in/set-72157600232700728/ I import my images and generate control points with autopano-sift-c. The problem is that not all images are connected, as seen from the Layout view, only about half of them are connected, the others are in the top-left corner and the output doesn't make any sense. https://lh5.googleusercontent.com/-MIhb_gh_4tQ/UBBF9r1icyI/Auo/57tgvgKOaVI/s1600/Screen+shot+2012-07-25+at+21.15.01.png https://lh6.googleusercontent.com/-wj03bDUYzWQ/UBBGaF6l8FI/Auw/i6mKnubEuBM/s1600/Screen+shot+2012-07-25+at+21.10.30.png -- You received this message because you are subscribed to the Google Groups Hugin and other free panoramic software group.

Re: [hugin-ptx] Garbage output despite many control points
I hardly use auto generated control points, but have heard that the new cpfind works much better than autopano-sift-c. It comes with newer versions of hugin. What version are you using? I would suggest that you create few well distributed control points in one horizontal line of images first, and also create some vertical and horizontal lines if possible, than optimize and then connect the rest of images. Sorry if something is said in the tutorial, flickr is blocked from where I am accessing internet now.

Re: [hugin-ptx] Garbage output despite many control points
If you don`t want to make control points manually (I usually do, as I said) you can also try to make them automatically in parts. Go to the Image tab, select only part of the images (like those correspondent to one only horizontal line or those that were disconnected) and with them selected press the button to create the control points. You can also do that after the global point detection step. I also don't have good experience with optimization made automatically. I usually do a first step to one horizontal, in three steps, y,p,r / y,p,r,v / Eveything without translation. Anyway, I also know that many people do spherical in different ways. It is really usual necessary to try many alternatives to find the best way for you and in the middle try to understand the details. If you search for recipe or other words in the list history you will find many ways to do the same thing. Here is an examplehttps://groups.google.com/forum/?fromgroups#%21searchin/hugin-ptx/recipe/hugin-ptx/XFu5PRRfIIk/0QhYFoJIQ9IJ . For a spherical it is also very important that you have used a panoramic tripod head. Without it you will have much more trouble to solve.
