Maybe a native speaker can help. Ah, I thought I suggested that in my first round of typos. Yes, the comma should go away. I'm torn whether it should be "which" or "that" though, but leaning toward "that".

Re: 回覆:Re: [hugin-ptx] Failed exposure fusion?
> If the three images have some slight geometric > difference,should it be set as same stack? Short answer: Just keep them separate for a single stack. Long answer: I don't think there's any advantage in using the same stack number unless you're blending a panorama of *multiple* stacks - then it helps with masking if you need it. You can set them as the same stack and uncheck the "link" checkbox for the position parameters, but it's easier just to leave them in separate stacks. Separate stacks allow you to use the X,Y,Z position parameters too, which I don't think can be unlinked within a stack.

I regularly use Hugin for just that. It may not be the best tool but it works for me. Some tips: - Use rectilinear for the output projection to keep a rectangular image. - For the geometric alignment (if needed), use the align_image_stack control point detector. Anchor one image completely. Optimize only image positions, not lens distortions. - For the photometic alignment, only optimize response, or nothing at all. Certainly not vignetting or exposure.

I've not noticed it with straighten, but centring often flips the yaw by 180deg with 360deg panoramas. (Yes I have tried to centre a 360, I'm that smart...)

After the fine-tuning, the numbers should always be correlation coefficients. Sometimes they are indeed a little >1.

Can you switch > between the two? Pressing "select by distance" (and using negative threshold values) should just do the right thing after fine-tuning. I don't know of any way of switching between correlation and distance other than to rerun the fine-tuner or optimizer. > - you say that you first do a position only optimisation, then remove > problematic points and then do further optimisations. These are still > position only right? I normally optimize the positions (incremental from anchor); then straighten and centre in the preview; then calculate optimal size in the stitcher tab; then re-optimize the positions; then add view (for 360deg or multiple lenses); then barrel b; then d, e, a and c; and finally X, Y and Z (narrow scenes with no/implicit stacks). I remove obviously wrong points (mismatched features, or >50 pixels) as soon as they become visible in the preview, but I don't start trimming the smaller control point distances due to parallax until the end, repeating the final optimization till I'm happy with it. This is just habit; you can probably go straight from the position optimization to the final optimization without the intermediate runs, and repeat it whilst trimming control points. > - it seems the align button in the assistant tab does more than > position optimize + photometric optimization.

What > is missing? What else does it do? I don't know what else the assistant does, but I assume (hope!) that all its functionality is available in the other tabs. The "...new alignment is needed" message appears for me too after photometric optimization, but since I've already aligned everything at that point and I can't see how photometric alignment can alter the geometric alignment, I just regard it as a quirk of the way the assistant tracks changes to the image metadata. Maybe someone else here can enlighten us about that? > - when performing photometric optimisation, I need to use HDR, fixed > exposure to avoid having hugin correct the under and over exposed > images, right?

Re: [hugin-ptx] Stitching and enfusing a handheld panorama with several exposures
Hi, Markku Kolkka wrote: > Don't use stacks with hand-held images. Hugin believes that > images in a stack are pre-aligned perfectly. Explicit stacks do help with some other things though (cpfind+align_images, whole-stack masking etc.) Just remember to uncheck the "link" checkbox in the images tab for all the stacks (it's in the image orientation section). This allows images to be aligned within a stack, at least in angular space. (There seems to be a bug with XYZ alignment not being properly unlinked even though the optimizer assumes it is, but I haven't investigated that yet to report it, and XYZ isn't an issue for wide panoramas anyway. XYZ does help a little for parallax on flat-ish ground with less than 180deg though, so in that case I unstack the images after creating control points.) My method (working hand-held) is to take the photos with the camera settings basically as you do. Then in Hugin 2010.04: 1) Set up *unlinked* stacks. 2) Mask moving people etc. 3) Temporarily mask out any obviously parallaxed foreground. (Assuming that you prefer the background to be properly aligned.) 4) Run "cpfind (multirow/stacked)" on all. As far as I can tell this uses align_image_stack within stacks and normal cpfind between stacks. Cpfind seems to be aware of the masks, but align_image_stack isn't - deal with that in step 5. I then remove bad control points: 5) Edit->Remove control points in masks - this eliminates the masked out foreground and moving objects. Remove the temporary foreground masks now. 6) Run Celeste if there are clouds. 7) "Clean control points" button to remove outliers. 8) Edit->Fine tune, then remove points with <0.8 correlation. <0.9 works well if you only use align_image_stack, but cpfind creates lots of points with lower correlations for me. 9) During optimizing, I remove control points in stages between rerunning the optimizer, based on their mismatch distance (e.g. >10, >5, >2, >1). Sometimes I need to manually add points between stacks. After the initial positions-only optimization and straightening and centring the preview, I use "calculate optimal size" in the Stitcher tab so that the pixel mismatches are accurate for successive optimization passes. For stages 8 and 9 use "View->Control point table" to select and remove points with low correlation and high pixel mismatch. Then I mask lens flares etc., do photometric optimization and blending as described. If the foreground looks too bad I crop it out. It's a bit overly complex, but for hand-held panoramas taken in the wind at the top of a mountain, computers just aren't yet clever enough to automate the process fully... I too welcome any suggestions of course, but this method at least is working well for me.

[hugin-ptx] Re: hugin blues
Carl, I've just checked the last Hugin image I installed, which was hugin- mac-2010-1.0.0 from early June. I know from the list that things have changed since then so perhaps I should give Hugin another try, when I have some spare moments.

[hugin-ptx] Re: hugin blues
I'd like to add my thoughts here on why I liked Hugin, but decided to use PTgui. I've just started with Panorama software, and am looking to integrate Panos and VR tours into my photography business. I'm a great advocate of Open source software, and was pleased to find Hugin, and it's associated programs. I've also a long track recored in computing before moving to photography as a career, so I was happy to tackle the challenges of getting Hugin to work However, after a number of trials, and some success with Hugin, I bought PTgui. I could get good (perhaps not perfect) results quickly with PTgui that I couldn't do with Hugin. And my criteria for choosing the software was getting my knowledge up and the ability to get a product to market as soon as possible - so the use of commercial software and consequent timesaving was, for me, the correct decision. These days I do most of my work on a Mac, having migrated from windows. I had some difficulty in installing and getting everything to work on this platform. It wasn't practical for me to use my Windows desktop to stitch panos but travel with a Macbook when taking the images. I guess the final thing was actually gathering up to date information on both program installation and operation - a common problem with open source. However, I still gather lots of useful information from this community, and perhaps will revisit Hugin as a tool when I can easily install and configure on my Macbook. -- You received this message because you are subscribed to the Google Groups "Hugin and other free panoramic software" group.
