  1. Bob - In the other cases on this forum where folks have reported this problem it turned out to be the issue of spaces somewhere in their path name. This doesn't just mean your image file names, but anywhere in the path of where your files live. The simplest way to check for this is to go the "assembly-files" folder and open the .lp file (this is the light positions file) You wil see in there a list of pathnames each on their own line, after a line with a single number, which is the total number of images. If there are spaces anywhere in this pathname or any of the filenames, that is the problem. If you aren't sure about this, then paste a line from an .lp file here. Here's another thread with this problem - and that's what it turned out to be: http://forums.culturalheritageimaging.org/index.php?/topic/312-rti-builder-asking-me-to-specify-your-hsh-fitter-path/ Carla
  2. We do not believe that this is a problem. This is old software that hasn't changed in a long time. There are some patterns that seem to trigger some malware detection software. It's noted in various places on the site. Carla
  3. That's odd - for the HSHfitter it should just know where it is. (unlike the ptmfitter, where you have to tell it the path where you installed it) One thing to check, is to make sure that you actually installed the software by dragging it from the .dmg (disk image) into the applications folder. Then start RTIBuilder from the applications folder in the installed location. If you try to run it from the disk image, it can create these kinds of path issues. Carla
  4. These look like some great examples. It took a really long time to load the first example when I went to the page, but once it loaded others were faster. It took so long that I thought it wasn't working correctly, and tried it in a second browser - where I had the same experience. I'm guessing it is a slow server connection, since the header graphic on the page took a while to load too. We shot some medieval lead seals in 2005, but they were never published, due to permission issues from the collection. We thought RTI was a great tool for this type of material. I'm aware of other individual examples of seals being shot, but not a larger scale project. If you want this page publicized at any point, let us know. We are happy to link to it on social media, it's cool stuff. Carla

    JPEG Library Error

    The problem is clear. There is a space between Research and Projects in your directory structure. You can rename this folder, then it should work. The issue with spaces occurs anywhere in the file name path - not just the image file names. The good news is that the fix is easy, and secondly, that you can open the existing .xml file for the project and go straight to building RTIs on the last screen, since you have already detected spheres and highlights. RTIBuilder will ask if you want to reset the path (since the stored path will be different) say yes - and away you go. Instructions for opening an existing project can also be found in the user guide. Carla
  6. Kevin - I've looked at this a bit. I think from the spread of photos shown in the report, that there may be some issues in the middle section of the area shot, due to how spread out the images are. Overall, I think this is a tricky scenario because of the moving pine needles, and also the shape of the bones. You could do a pass over the top (as you did) and get the placement of the bones and probably decent measurable data on the length of bones. You would likely ned additional shots at more inclined angles to get more of the bone structures themselves. I'm not sure if this is clear, and part of the question is what your goals are in doing this type of capture? Would you go back and image the bones separately "in the round" or at least some of them - and the initial scatter is to document how they are laying in the ground in a measurable way? Overall, my biggest piece of advice would be to get a pole and harness and try it again (as I already mentioned) Carla

    JPEG Library Error

    Andrew - can you copy and paste a line from the .lp file that has the full pathname here? Carla

    JPEG Library Error

    What I was suggesting was to look in the assembly-files folder for the light position file - which will have the .lp extension. Check the pathnames in there to make sure there are no spaces anywhere in the path. If you find any, then you need to move the folder - with all the sub-folders to a new location that doesn't have this issue. Then you can "open an existing file" and you should just be able to build the results. In other words, you shouldn't need to find the highlights and sphere again since that is already done - assuming you resolve any issues with pathnames. There is another listing with this error message - I searched on "jpeg library" and found several entries - including the one I linked to above. It isn't smart search, and sometimes you have to choose less terms rather than the full message, in case others didn't type in the exact message the same way. Carla

    JPEG Library Error

    I think that the uppercase JPG issue is specific to PTMs. There are various programs that can rename files. I use an application called forklift - which I generally use for comparing drives and backups to look for differences, and then sync things, but it happens to have a file rename feature. There are many other options. I do recommend that you rule out that there are any spaces in your filenames or pathnames. The easiest way to do that is by looking at the .lp file that was generated for your data (in the assembly-files folder) And check the full pathname. Good luck!

    JPEG Library Error

    This error is discussed elsewhere on the forum - including this post with the error name in the post heading - which links to another thread. http://forums.culturalheritageimaging.org/index.php?/topic/207-improper-call-to-jpeg-library-in-state-200/ Here are the highest likelihood errors with RTIBuilder First are there spaces anywhere in the filename or elsewhere in the full pathname of your files? Are you using uppercase "JPG" rather than lowercase jpg? There is a bug in the ptmfitter that doesn't allow use of the uppercase JPG. If you are on Mac - you can't run RTIBuilder from the disk image (.dmg) you have to drag RTIBuilder to your applications folder from within the disk image. All of these are further explained in the linked discussions.
  11. Thanks Ponchio! Just to be totally clear - the service converts .ptm and .rti files to be used in the web based 3D Heritage Online Presenter (3D HOP). You have to create the RTI's first, using RTIBuilder - or a similar tool. So essentially, the tool takes away the need to find a windows machine to do the preprocessing on an RTI file, and it sets up the results in 3DHOP - which supports 3D models as well as RTIs. The 3D HOP viewer was created by the Visual Computing Lab folks at CNR-ISTI in Pisa who also wrote the RTIViewer that we make available and the RTI web viewer mentioned above. Also they wrote Meshlab. It's a great team!
  12. Leszekp has some good advice. In addition, I'd add that Marlin developed a harness system that keeps the camera at about 5-6 feet off the ground, and away from your body. We have used it to walk around areas we want to capture. You can see a picture of it here: https://www.facebook.com/culturalheritageimaging/photos/a.356002304439118.78214.127514043954613/1469987609707243/?type=3&theater The sketchfab model looks to be really decimated, so it's hard to tell what's going on. How many shots did you take? What's the resolution of the camera? And are you getting enough look angles? In my experience the "wavy" pattern on a surface is an indication of not enough look angles on that part of the model. You can also run a report in Photoscan and look at the color coded chart for look angles. It IS tricky to walk around and get this right, but it can be done, with some planning and practice. The pine needles do make it harder, so you want to keep outside of your area of interest as best you can. You could use a longer pole than what is shown in the image above. We have successfully captured an areas about 10 feet by 10 feet using the length pole in the photo, and keeping outside of the area we are shooting.
  13. Marlin has better images and he built the rig. He's on holiday until after the new year. I'm sure he'll add to this discussion after that. Carla
  14. This was built from a panorama head that we had in the studio. So, it is a custom thing. Marlin can comment on the parts he used. The idea was to be able to turn the camera 90 degrees in either direction without changing the camera position right or left or up or down - so that it remained centered between the lights. I'm attaching a photo of the rig.
  15. As I said, I have never seen this error before - so it is hard to track down. Did you mean to say that you have 246 images in one RTI image set? Or maybe that was a typo. We generally shoot 35-50 images and have never gone over 80. The minimum we recommend is 24. It is odd that things are working for some image sets, and just not one image set. Can you email the .xml log file to me (info at c-h-i.org) maybe there is some clue in there. Carla
  16. Hello - The HSH vs PTM is discussed at length in this topic: http://forums.culturalheritageimaging.org/index.php?/topic/306-scientific-method-hsh-vs-ptm/?hl=%2Bhsh+%2Bptm It's really a processing issue - not a capture issue. As for your quality concerns - please be more specific about the "poor quality" RTI. There is image degradation creating JPEGs - however that is what the current software supports. Depending on the problem you are seeing in the result, it may not be related to image quality. For example, if anything in your setup moved, even a small amount, that can cause blurriness in your finished RTI. Carla
  17. I want to make sure that you are receiving the same error message about the color correction file, and not a different error? If you get "unknown error" in the popup window, the culprit is likely that you have spaces somewhere in your filenames or path names. There are Windows and Mac versions of the ptmfitter. The Mac one runs on a Mac - it isn't a windows file. It does not have an extension, and is just called ptmfitter. I work primarily on Macs. The fact that it worked then stopped working is very curious, and unusual. I don't think it has anything to do with your image sets, it is something in the RTIBuilder configuration. If the issue is that you are still getting the color correction file error, then you could try to delete RTIBuilder and reinstall it from the disk image (downloaded .dmg file). I know that isn't the most helpful suggestion, but it might do the trick. Carla
  18. Just to clarify you received the same error: "plugin.exceptions.pathundefined: color correction file not found or you don't have permission to read it." and this appears in a popup window? In normal operation RTIBuilder has to create a cropped file for each image, and then it hands off the images to the fitter. The Fitters are separate programs, and they don't provide much feedback. RTIBuilder reports the feedback from the fitters in the information window (where the running list of cropping images was) It's a bit confusing, and sometimes folks think that the system is finished when RTIBuilder hands over the operation to the fitter. If you just received the "Parameters read successfully; HSH matrix: rows=4 and columns=62; number of threads: 8" in the information window, then everything is good, it just needs time to calculate your file. Let it run, and then you should get the "fitting complete" popup. If however you had an actual error popup, then I'm wrong. I just wasn't sure from what you wrote here.
  19. Hi Rob - First, you should not need to reshoot your images, there is something going on with the processing. If you are using the HSHFitter, do NOT turn on the advanced options. That's probably what caused the error with the color correction file. You can try opening an existing project with the Highlight based (HSH fitter) option selected and go to the log file created before. This will take you right to the last screen where you can try again to build using the hshfitter. Make sure to use 2nd level and no advanced options the first time through. For the PTMFitter, you need to download that from HP, then wherever you install it, you need to browse to it (one time) in the final screen of RTIBuilder - on the "ptmfitter path" Once it is set up, it should remember that location and not be a problem going forward. I know this is weird because it worked for you a couple of times. Is it possible that this path was reset? Carla
  20. Hmm - I don't know what is going on. Can you email your .xml file to info at c-h-i.org? I'll take a look and see if anything looks obvious. I note that you previously posted about having an issue executing, and the screen shot showed you were using advanced options for the HSHFitter. You should make sure to quit and restart RTiBuilder after that error (which may not be related) You should be able to open an existing project, and not have to do the highlight and sphere detection again. That's described in the manual if you don't know how to do it. Have you been able to successfully build a ptm? Is this happening when you do hsh? Please let me know what you have tried, and which fitter you are using. Carla
  21. Don't use the advanced options with HSH. They shouldn't have been put in the interface. You can choose between 2nd order and 3rd order. The other options won't work. Carla
  22. One more note - I just reread this, and I think that the idea of "importing" the files is the key one. The RTIBuilder assumes a specific file structure. Your images MUST be in a folder called "jpeg-exports" Then in RTIBuilder, you give the folder containing that folder, and it will load the files. This is described in the documentation on page 9 and again on page 12. You can get the Guide to highlight image processing here: http://culturalheritageimaging.org/What_We_Offer/Downloads/Process/index.html Also note that if you want to use a pre-determined light position file - you should use the "dome LP file" option in the first screen (PTM OR HSH as you wish) Carla
  23. Ayman - this really belongs as a new topic in RTI processing - this is a photogrammetry forum. I can move topics, but not individual posts. At any rate, I suspect it may be that you have some movement somewhere in your image set. Either the subject moved, or the camera moved. Even a few pixels can cause the RTI to appear blurry. In RTiBuilder, you can sometimes spot this, by choosing the first image then the last image in the sequence, after the sphere is detected. If the circle isn't in the same place on the sphere, then that means either the camera or the sphere moved. If it was the subject that moved, then this won't tell you. You can try loading the first and last image in layers in photoshop and zooming way in like 400%) then turning a layer on and off. That can tell you if there is a misalignment. We have a tool to fix misalignment in image sets, though we haven't had the fund to finish it and release it. I do have a beta version for Mac only, if that helps. Otherwise, you can try aligning the images in photoshop, or some other tool. Hope this helps. Carla
  24. Thanks Leszek, that's exactly what I was going to ask. I'll also clarify that Cultural Heritage Imaging doesn't have a "customer service" department. We are a small independent nonprofit, and we set up these forums so that the community could help each other out. This is especially important given that the software is open source. We do work to keep the forums free from spam and other nonsense, and we answer a lot of questions as well. But really, it's purpose is to help the community help itself. It does cost us some money to run the forums, but we try to keep costs down, and we really appreciate everyone who jumps in with their experience and advice. Thanks to everyone who participates here! Carla
  25. Dear Ayman - There is some discussion of this problem in another thread - and I think you already have that link: http://forums.culturalheritageimaging.org/index.php?/topic/207-improper-call-to-jpeg-library-in-state-200/?hl=%2Bjpeg+%2Blibrary Check that you do not have any spaces anywhere in the file names or directories for your project. Then there are some other things to check, noted in the above thread. If you still need help, please provide what platform you are on (Mac or Windows) and also what operating system version you have. And also are you trying to create a PTM or HSH based RTI (or if you see it for both). If you tried one, please try the other and see if it works. Carla
