Re: [hugin-ptx] Windows - unable to align images; artefacts and unhandled exceptions
Wow... I am following your walkthrough and it's... amazing. Going to expert mode really changed a lot. And in all my time using the program I never even heard of the f3 thing. I'd ask where you learned of it but you'd probably say that it's in documentation. Honestly though, I haven't seen anything similar. Feels like the mode change switch the algorithm used too. It's not perfect but at least this time it has shape.

Re: [hugin-ptx] Windows - unable to align images; artefacts and unhandled exceptions
Thank you for your in-depth reply, I'll give your walkthrough a go. I'm sorry the format is confusing, I am somewhat embarrassed now. There are no real "requests" as far as features are concerned, but the txt file holds a list of things I found could be improved for convenience. As far as I know you can do everything in the way it is now (as long as it works properly), but context menus are the biggest idea I think. Then there were things I didn't know what to make of so I just described in a general manner, hence the pictures. If there was an error log I would have sent that too. -- A list of frequently asked questions is available at: http://wiki.panotools.org/Hugin_FAQ --- You received this message because you are subscribed to the Google Groups "hugin and other free panoramic software" group.

I doubt that this mode is sufficient for the type of panorama you want to achieve. Please switch to expert mode and create a new project. Then use the "Add images .." button to add your images to the project. The next step would be to set the stack size. Right-click into the list of images and select Stacks -> Set stacks size. Here, you have to set the "Link positions of each image in Stack", too: If your images were shot on a sturdy tripod and you are sure that the stacks do not need additional alignment, you can set this tick mark, otherwise remove it. Next step is to create control points. However, I assume that Hugin's CPFind somehow takes the lens type into account, at least I get much better results for my samyang images when setting the lens type to Stereogrphich instead of the default Normal (rectilinear). I have no idea what lens type you used, so you may have to google this or experiment with the various options. In any case, make sure you select all the images and then set the lens type properly if it is not set so already. Clicking on "Create control points" finishes this step. Now it would be a good time to save your project. I normally then move to the Optimize step. First, I do "Positions (incremental, starting from anchor)", then "Positions and view (y,p,r,v)". This would be another good point in time to save your project, by the way. Afterwards, I do a first rough pruning of the control points. For this, I press F3, then "Select by distance" and accept whatever Hugin suggests. Pressing the delete key gets rid of the control points that lay outside of the value chosen. I may have to repeat the Align and Delete steps a couple of times until the maximum distance is below 5 or 2, or 10, or .. This really depends on the quality of the shots and the number of control pints I get. You will need to leave enough control points so all your images stay connected, but the more outliers you can eliminate, the better the panorama will turn out. Afterwards, I set the geometric optimization to "Everything without translation" and repeat the optimizing and pruning until the maxiumun distance is below 1.0. Next step would be to run the Photometric optimizer. When doing HDR, one of the "High dynamic range" settings is recommended. If this is not a full sphere panorama, some fiddling with output projection type, centring, fitting, straightening and cropping is required next. Then, we switch to the stitcher tab and define the output image type we would lie to get. Press Stitch! and enjoy! Clicking align always > leaves out at least one image. I can not comment on this as I never use simple mode. However, the last image just may not get any control points, so it is being ignored by hugin.

Dragging images around in a botched pto can lead to severe geometrical problems that may not be handled properly because nobody tested this specific situation.

If the lens type in your project does not match the physical lens type, things like this can happen. Additionally, for an algorithm, it is very hard to find control points in images mostly containing snow. But without being able to have a vclose look at the images and the ptos, this is ll speculation. > If project watered down to 6 images in cylindri

Any way I can fix that?* Not directly. The Tiff library used in hugin happens to be very vocal when encountering files that do not specify all the parameters that define the type of image inside the tiff. However, some of the programs creating those tiff files use other libraries, and those libraries seem to be a little bit sloppy in this regard. Here, you program that created the tiff files felt it to be obvious that the sampletype tag should be unsigned 16 bit integer and therefore refrained from explicitly specifying this. libtiff, however, expected this tag to be specified and complains that id wasn't. Because it probably guessed correctly, the images are displayed by hugin without strange colors, so no harm caused here. If you really want to get rid of this error message, you have several options: o complain to the producer of hte program you created the tiff files that the sampletype tag is missing the the tiffs produced by hi software. o convert the tiffs in a program that properly rewrites them. Because these messages are irritating at the most, I'd recommend to simply ignore them. With kind regards Stefan Peter -- A: Because it messes up the order in which people normally read text.

[hugin-ptx] Windows - unable to align images; artefacts and unhandled exceptions
Good afternoon everyone. I'm glad I finally found a group for my hugin... questions. For I have many. Win7, 64b NVidia graphics card (didn't make a difference yet but maybe relevant) First, let me express my appreciation for the software - I have been using Hugin on and off for years now. Around 2011 I even did more panoramic work in it than in Photoshop, but recently I've been struggling with the software: Note: I need TIFF to create an HDRI for equirectangular high-bit 3D environment map. ***Quick enquiry:* TIFFDecode also keeps throwing "no datatype, sampletype, guessing uit16". Any way I can fix that? ***Problem 1*: There are about 22 tiff photographs taken with a gopro; lot of snow, treelines in medium range. The images load normally and camera data is read - about 3mm focal length at 5 crop factor. Clicking align always leaves out at least one image. After I assign control points and click align again something weird happens every time. Links will be active for about 6 months. http://pasteall.org/pic/index.php?id=112887 http://pasteall.org/pic/index.php?id=112888 I noticed that I can drag images by clicking on the sphere. If I try to do that in this case an unhandled, unknown exception message pops up. I can ignore, abort or retry, though no change happens. ***Problem 2:* Alignment doesn't work. Project is the same - 22 tiff files, 3 layers of exposure, 6-7 stacks. Stacks don't align automatically, and after putting them into groups manually they still often form 0 new control points (CPFind nor align_image_stack) After assigning a few of my own control points the software still finds no others by itself. If project watered down to 6 images in cylindrical projection with no stacks still no effect. Does drag/move tab have any relevance for finding control points? ***Feature requests:*First let me say that I know how much work goes into implementing new features. wish I could code them myself but I'm not good at it. Regardless, most of these are things I grew frustrated with after doing the same thing for the seventh time, and I believe that it could make use of Hugin much easier, potentially expanding the audience. At the very least I have not met many who know about it even though, as I said, it used to be better than Photoshop. *--*Wow, what an introduction. -- A list of frequently asked questions is available at: http://wiki.panotools.org/Hugin_FAQ --- You received this message because you are subscribed to the Google Groups "hugin and other free panoramic software" group.

Either broken or use completely counterintuitive. control point interface awkward: everything needs RIGHT-CLICK CONTEXT MENU lines in CP tab always set as vertical if automatic needs system to reclassify multiple lines at same time, because often automatic horizontal understood as vertical. Either that or system unclear on use of horiz/vertic zooming in/out requires too much clicking - specific mouse pointing; should be scroll, +/-, wsad or something. needs hotkeys to add point, vertical line, horizontal line vert/hor lines too often break into inverted circle TIFF input very often problematic (not guessing uint16...) workflow unclear - everything ok when 1. 2. 3. works ok; when two-step problem occurs everything breaks: what does what, what influences what else (layout/move drag make difference? manual CP no effect on automatic CPFind) Add/remove needs mask automatically added on click on picture in masks tab, default to exclude, right click menu -> include if otherwise Control point menu: left click add point, right click add line or drag image == Important things that I know nothing about so I don't like to point them out: CPFind often finds nothing even after user set some basic control points. Roll Errors when aligning - stacks adding 0 CP for shots with good coverage Program loops, freezes, buggs out or crashes when you misalign the simple/advanced/expert interfaces too much. Meaning you click from simple to advanced, then in advanced you area already at simple, you work in simple but then you try to reset advanced to simple but it doesn't work and when you try to put simple to advanced again it crashes. Or something along these lines, basically two windows kind of make a problem.
