  1. I'm guessing the issue is the size of the RTIs. You might be able to open them on a beefier computer. Though, in general we have successfully opened files made from a 50MP camera and full quality Jpegs on a machine with 16GB RAM. The RTiViewer will try to open large files, and may fail if it can't open them. Usually it fails without issuing an error - so I'm surprised by the internal filepath error. I haven't seen that before. Thanks Dave for jumping in on this one! Carla
  2. Musa - I replied to this in the DLNCC forum. Please post there if you have further questions. Carla
  3. Welcome to the forum for discussions about Nigerian Cultural Heritage preservation and documentation. We welcome discussions about any topics of interest for folks working in Nigeria, or interested in preserving Nigerian culture. If you have questions about Reflectance Transformation Imaging (RTI) or photogrammetry - please use one of the other appropriate forums for those questions and discussions. Carla

    Question

    Musa - We use the database to help organize and keep track of the information you enter using the DLNCC tool. This also helps with reusing data you already entered. The installer installs the database, and when you run DLNCC it will be able to connect to the database using a default password. So, if the Postgres application is running, then DLNCC can connect to it and work properly. If when you try to start DLNCC it asks for a password for Postgres - then "cancel" and start Postgres yourself (by double clicking on the application) then run DLNCC again and it should work. In other words, Postgres has to be running before you try to run DLNCC. By default it will run every time you startup your computer. If you are actually trying to look at the database in Postgres, we do not advise that, as the design of the tables and their relationships was to be used only with the DLNCC tool, and DLNCC is designed to manage the data and export the data and relationships. You should not try working with the database directly, only through the DLNCC interface should you enter information. Carla

    Color correction for HSHfitter

    The PTMFitter is available - and I posted it in the FAQ forum pinned to the top, as well as in the thread where it came up. We have created a dropbox with the files: For HSHFitter - try using it as installed - and staying away from the advanced options. In other words Do NOT tick the box for advanced options. Carla

    RTIBuilder 2.0.2 now available on CHI website

    The page with the workaround noted above is no longer available. I was able to install RTIBuilder 2.0.2 on MacOS Mojave with instructions from this page: https://techsviewer.com/allow-installation-of-apps-from-anywhere-in-macos-mojave/ They show multiple options, but the only one I was able to make work was to disable the "gatekeeper" which puts open apps from :"anywhere" back on your preferences window. Note that you can open RTIBuilder once, then change your setting back to just from identified developers, until you need to allow an app to open again. Other methods for overriding allow an app from an unknown developer, including from the Apple Manual did not work. The system detects that the app is "damaged" meaning that it was modified after it was signed. Note that there are many legacy apps where this is true, and they say that you can override it by using control click on the app and open, but that didn't work for me. I continued to get the damaged app message. However, disabling the gatekeeper (i.e. putting "allow apps from anywhere" in the security preferences did work. Carla
  7. The RTIBuilder version 2.0.2 version along with documentation and an example data set is available here: http://culturalheritageimaging.org/What_We_Offer/Downloads/rtibuilder/index.html RTIBuilder is open source software made available under the Gnu General Public License version 3.

    Wow! You folks are having a very difficult time. I'm sorry to hear it. We mostly work on Macs in our studio - though we have worked with Windows machines in training classes, and we recently added one to our collection of computers. The computer you describe should be plenty powerful to build 50MP RTI files. We also have a 5DSR for more than 3 years, and build RTIs from those images on a regular basis. We know about HPLabs taking down the ptmfitter - and most of the PTM pages from their website. We've made the ptmfitter available in a dropbox - we posted that here to the FAQ forum: I can't really explain all the problems you are having. One thing to check is whether you have rotated all the images in the image set. If there is one that is portrait for example and the rest are landscape, that will cause problems with the fitters. If you are shooting images with the camera hanging down from a tripod - or from a camera stand, then it will sometimes "auto-rotate" the images into different orientations. We recommend turning off auto-rotate and then rotating the whole set of images at once, when needed. There is a discussion comparing HSH and PTM here - there are trade-offs: That's all I've got time for tonight. There are other posts about the JPEG library error on Windows in the forum - you can try searching for that. I wish I had a better answer for you, but I'm kind of scratching my head at this point. I'm hoping other folks will chime in. Carla

    Thanks Dave - good suggestions! I'll add that the xml file indicates the error is in ptmfitter: DATEF="" DATES="" LEVEL="WARNING" USER="">Fitter returned an error ! Error : -1</xc:event> We see that in the screenshot as well, that ptmfitter is not able to open the file. So, try building an RTI with the hshfitter and see if that works. You have plenty of memory on your computer, and we build files this size with a less beefy machine. However there have been some issues with large files with the ptmfitter on Windows that don't occur on Mac. Also, are you rotating the images before you put them in RTiBuilder? In other words, are the images landscape or portrait, and are they all the same? They really need to be all the same. Hope this helps. Carla

    Can you say more about the computer you are using and it's specs. For Example Mac book pro with 16GB RAM and MacOS 10.12.6 Also - you can look in the .xml log file that RTI Builder produces, which will sometimes give you a clue as to what is going on. In this case- from the screen shot it appears that RTiBuilder is successfully making all of your cropped files, and the failure happens within the PTMFitter. The fact that the PTMfitter can't open the file, might indicate a permissions problem. Where did you instal the ptmfitter? Are you able to build HSH based RTIs? the HSHfitter is included with RTIBuilder, so it should just work, without installing extra software. One other thing to try is to make smaller jpegs and see if it works - We regularly make RTIs of this size or larger, but we have fairly "beefy" machines with a lot of RAM (16GB - 128GB) Carla PS: If you don't know what the "fitters" are - you might want to check out the Glossary: http://culturalheritageimaging.org/What_We_Offer/Downloads/Capture/CHI-RTI-Glossary_v1.pdf

    Basic hardware

    I think that John is interested in RTI - which doesn't require as beefy of a system as photogrammetry does. The good news for RTI is that it will work on a broad range of systems, though it will definitely be faster to process on a faster machine. Also, this somewhat depends on the resolution of the camera you will be using, and therefore the resolution of the finished RTIs. If you have 16GB of RAM you will be handle most RTI image sets and also load and view them in RTIViewer. I agree with Leszekp about the graphics card if doing photogrammetry, but not as critical for RTI. If you are doing a lot of photography with high resolution cameras (>25MP) then this will definitely help you. So bottom line is max out the RAM and CPU and graphics card for what you can afford. 16GB is an absolute minimum to work with high resolution images (including RTI) - and 32 if planning for photogrammetry. Pay attention to the the other components too, and not just RAM. Carla

    PTMFitter software download link

    We recently discovered that the PTM software is no longer available from the HPLabs website. We have placed both the Mac and Windows versions of the PTMFitter in a dropbox along with the license file from HP. You can get the software from here: https://www.dropbox.com/sh/jfsy0lhxu6zv4i4/AADJpq6E_GJmNw_s5C8r94CVa?dl=0 Also - many papers on PTM and RTI are by Tom Malzbender - and you can find them on his personal website: https://sites.google.com/site/tommalzbender/

    PTMFitter software download link

    I rebuilt the zip file using a different tool. I tested it - and it seems to be working fine. The original version tried to put it back in my applications folder when I unzipped it. So, hopefully this will fix it - as it seems to work correctly. Carla

    PTMFitter software download link

    In the dropbox are two folders one for Mac and one for Windows. In the Mac folder is a copy of the PTMfitter I have on my mac and run regularly. It doesn't seem to have an extension. I have it in my applications folder. I don't have a disk image or installer for it. I think it should work without an extension. I just tried downloading it and dropbox adds an .html extension to it. When I remove that it still thinks it's an html file when I run it from the terminal. So, I've uploaded a new copy as a zip file. Unzip it - and hopefully that will work. I don't know what the dropbox downloader is doing to the file - but it doesn't seem to like a file with no extension. Note that it's a command line tool, and not designed to work by double clicking on it. You could test it by running it from a terminal window if you are comfortable with that. Or just browsing to wherever you unzipped it from RTIBuilder in the last screen (where you execute the RTI) Carla

    Adding Scale Bars after alignment

    I think there was an error in the above recommendations - you absolutely need to align the images with the scale bars in order to use them to set scale for your project. How you placed the scale bars will affect exactly how you work with those images. The Agisoft software will not be confused by some images that have scale bars and some that don't for the same area of your scene - as long as you have good crisp photos with good overlap between photos and plenty of look angles. It's a bit difficult to describe in text, but hopefully this makes sense. Carla

    Adding Scale Bars after alignment

    If you shot it properly, all the images should align together in the same chunk. Also for a turntable project, you likely need to mask background images, and then when you align, apply masks to tie points (in the advanced tab) You do not need to mask the scale bar images. You can set the region of the model later in order to remove the scale bars. There are other ways to remove the scale bars as well - but initially, you want them in the main alignment. If they don't all align together that may indicate a different problem (such as blurry photos, monochromatic surface with no texture, etc.). In that case you can align them in separate chunks and try to bring the chunks together. Just understand that at that point you are working around a problem and a properly shot image set should all align together. Hope this helps, Carla

    RTI Builder Versions

    We were working on a version 3 some years ago, and we gave a Beta version to some folks who took classes with us. We were never able to release it due to some bugs that were too difficult to resolve (long story). So, it is possible that you have a 3.0 Beta version. I recommend going back to the 2.0.2 version from the website. The 3.0 Beta is known to not work with higher resolution images, as well as having some other issues. Even though 2.0.2 is marked Beta - we really should have marked it final. It's getting old now, but it's the best option for current use. We are very interested in doing a new version, but it will take some funding, and we haven't been able to make that happen yet. Carla

    PTM fitter no more available

    We recently found out about this. I've set up a dropbox folder with both the Windows and Mac versions of the PTMFitter, along with the license from HP: https://www.dropbox.com/sh/jfsy0lhxu6zv4i4/AADJpq6E_GJmNw_s5C8r94CVa?dl=0 Carla
  19. There have been some reports of problems with newer Macs (running 10.9 and later) where a message stating that the RTIBuilder download is damaged appears. This is a known problem that started with MacOs 10.9 and later, because Apple changed their security checks. We do not believe there is anything wrong with the RTIBuilder download. As a small nonprofit company, we haven't paid to be in the Apple Developer program, and so the content is unsigned. Also a small script runs when you install the software (it basically just sets up a path to the software) and this is what is causing the error message. Note that the identical package on MacOS 10.8 and earlier will not generate this message. You need to change your security settings (found in the system preferences) to allow software downloaded from anywhere to run, and then try it again. You can then change the settings back.
  20. I just had to do this on Mojave - and it works like a charm. We are looking into getting the proper certificates so that our software can come from a "known developer" which would prevent this problem. The certificates cost money, and it's different for Mac and Windows. That plus work needs to be done on the RTI software. We are aware of this issue though, and we will do what we can to resolve it. We appreciate all of you that support our work with donations and volunteer efforts. It really makes a difference. Carla

    CHI's Resources for Photogrammetry Users

    We are focusing on good practice for collecting image sets for photogrammetry - which is independent of the software used. We feel that if people collect good image sets that follow the rules (as described in our videos) then they have useful information for now and the future contained in those image sets. Especially if they collect some metadata about what they are doing, their methodology, who was involved, the subjects and locations, etc. We are developing tools for that called the Digital Lab Notebook. While we do use Metashape (aka Photoscan) at this time, the methodology is not dependent on the software. So our freely available public information is not about Metashape. We agree that the Metashape community forums are a great place to go for information about working with that software. We do use an error reduction workflow in Metashape that is a bit different than the process most folks follow. We teach that in our training classes. We spend time looking at metrics and what they mean, and also trying to impart an understanding of the sfm photogrammetry approach, and how that informs the guidance we give on collecting image sets. Our goal is to impart knowledge rather than give a "cookbook" approach, so folks can deal with a variety of situations in their own work, and make the appropriate trade-offs to meet their needs. This kind of material doesn't fit into a forum post. Carla

    Scaling fix for RTIViewer on high DPI displays (Windows 10)

    Thanks for posting this! We recently got a 4K monitor we are using in a Windows environment, and ran into this issue (we are mostly a mac shop). We hadn't tracked down the best way to deal with it yet - and this is very helpful. Note that RTIBuilder (and some of our other tools like inspector and DLN: Capture Context) are written in C++ using the qt libraries for the UI. I'm guessing this is an issue with the qt libraries not handling scaling for hi-res monitors. We are seeing this problem with all of our tools. If you want to check out the Digital Lab Notebook (DLN) tools go here: http://culturalheritageimaging.org/What_We_Offer/Downloads/DLN/index.html Carla

    Import Images problem

    Hmm - I have seen this before - but nothing else is coming to mind at the moment. Is RTIBuilder producing an xml log file? It should be in the ProjectFolder in your example. It should have the name that you gave the project when you started the project. Sometimes there are useful hints in that file. Can you take a look and/or post it here? Carls

    jpeg-exports locaton on Mac 10.14

    Janis - You have to organize your images into a folder called jpeg-exports. The folder should be under a folder for your RTI project. For example a folder called "painting1" with a folder called "jpeg-exports" inside that. When you use RTIBuilder - you tell it to load images from "painting1" (Us the bowser tool to find that folder) Then it will look for a "jpeg-exports" folder within that folder. If you do not have a folder with that name, it will not find any images. This is documented in the RTI Guide to Highlight image processing: http://culturalheritageimaging.org/What_We_Offer/Downloads/Process/index.html I hope this helps. Carla

    Import Images problem

    Hi Josh - I have a couple of ideas. First are you using uppercase JPG for your filenames? There is a bug in the ptmfitter that will not accept files named myimage.JPG but will accept myimage.jpg. Otherwise I wonder if you have some kind of permissions issue. Are you sure that you have full permissions on the full path to where the images are located? I don't have a lot of other ideas off the top of my head, but those two jump to mind. Thank you for providing very detailed information about what you did and what happened. That is very much appreciated. Carla
