    Import to RTIbuiilder

    You need to give RTIBuilder the folder that contains the jpeg-exports folder - not the jpeg-exports folder itself. In other words, choose the folder one level up from the jpeg-exports folder. This is documented in the user guide, which can be found here: http://culturalheritageimaging.org/What_We_Offer/Downloads/Process/index.html Carla

    Why my rti file is invaild and internal format unknown

    IT looks like only one of these is a ptm file - the first one. The other are all a different (.dat) format. The PTM file at 1KB is not a valid file. The file sizes would always be larger than that. I'm not sure how these were shared with you. Is it possible that these files are the result of some pre-processsing step for Web distribution? There are a couple of web viewers out there that require that you take a PTM or RTI file and run it through a program to prepare it for Web distribution. If that's the case, then you can only open the result with the web viewer, after the files are properly staged on a web server. What you want is just the regular full size RTI (or ptm) file. Carla
  3. Thanks for the additional details. I'll note that you can associate a photo with a group of RTI image sets - which doesn't totally get what you are asking for, but is simpler than associating with each image set. Also, the ability to "duplicate" image sets and/or groups of image sets will also automatically associate the photo. I agree that these ideas are "workarounds" for what you are asking for, but thought I would throw them out there in the hope that you might find the suggestions useful. Carla
  4. Welcome to the forum for the DLN:CaptureContext (DLNCC) tool! DLNCC is one of the first two tools in the Digital Lab Notebook (DLN), a software pipeline made up of open source software and associated good practices. In this forum, we encourage you to share your questions, issues, or comments about using DLNCC. DLNCC is all about collecting rich metadata for your photogrammetry and Reflectance Transformation Imaging (RTI) projects. You can easily reuse data about equipment, people, locations, subjects and more. The data can be exported as Linked Open Data mapped to the CIDOC Conceptual Reference Model (CRM) for archiving and reuse. And, you don't need to know anything about these metadata standards to produce these results. You can download the Capture Context tool, along with a user guide from this page http://culturalheritageimaging.org/What_We_Offer/Downloads/DLN/dln-cc/index.html There are Instructional videos describing how to work with the tools on this Vimeo channel: https://vimeo.com/channels/digitallabnotebook Please give us your feedback!
  5. Hey guys! Thanks for figuring this out. I'm on the road doing training so just saw this. We definitely should make the default be to install the database. This probably needs its own topic where we can show the details and folks can find it easily. When I'm back on a computer (rather than my phone) I'll get that set up. Note that you may may need to start Postgres after rebooting your computer- or you will see the same message.
  6. Dave - thanks for the feedback. We are planning to internationalize the software to make supporting different localizations easier. I agree that dates can be tricky - and maybe we should just make the month and date formats clear as a start. Thanks for bringing up the dome scenario. Most folks are doing the highlight method of RTI - and this is a little bit skewed that way. Remember that you can enter as much or as little data as you want - so you can easily skip the string length - or use it to record the radius (i.e. the light standoff on your dome). You can make your own equipment category for a dome. Put in whatever you want about it, and associate an image or two of the dome with any groups of image sets - or image sets you wish. Good point about operator roles. Initially we were thinking about collecting the initial event of capturing the image sets, and so you can make these whatever level of specificity you want. I use "image capture" for a person playing multiple roles in the image capture. Good point about making it possible to associate the same person as the image processor. Thanks for the feedback! Carla

    DLN:Inspector version 1.0 Beta

    Thanks for the feedback Dave. Here are a couple of notes: 1. You can run inspector without the database from DLNCC - and that might be the easiest way to use it when you are just getting started. This is also great for checking your own legacy data, that isn't in the DLNCC tool. If you want to do this you can turn off using the DLN in the "options" pane. You can turn it back on any time you like. 2. If you want to use it with the sample data, you will need to change the path for the sample data to wherever you installed it on your hard drive. I should have included that in the README for the sample data - sorry about that. If you use Inspector with DLNCC - it assumes it can find the files and folders in the stored path for the project. So, update the path at the project level, and keep the sample files under that and it should work. Thanks for taking the time to try out the tools! I think you will find the Inspector reports really useful, once you get over these early hiccups. Carla

    Not able to import images.

    Sorry to be late in responding - the issue when you see the message "The jpeg-exports folder is missing in your project directory" is that you didn't give RTIBuilder the correct folder. When starting a new project, it is looking for a project level folder, that includes a jpeg-exports folder where the images are to be found. The folder MUST have that name, and you have to give it a folder one level up from that. This is all documented in the user guide. Carla

    Initial view bookmark?

    That functionality is not in the RTIViewer. It always starts at high noon in the default mode. Though it easy to see other views using the bookmarks. Carla
  11. 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.

    Coin imaging

    2-4 times is the minimum distance - you can always work from farther away - as long as you have good even coverage across your subject from the light distance. For example, we do this under microscopes, and we have the light much farther away, because we are imaging small things. So, you want a comfortable working distance that is easy for you to set the distance. For small things it is easy for one person to hold the string, and the flash. We often set the camera on a timer and then just move the light, and have it take images. There are several ways to use a timer, the simplest is being tethered to a computer. For example, Canon cameras come with free software - the EOS Utility that allows you to automatically take pictures every X number of seconds. Also this way the images can be named and numbered and saved to an appropriate location in your computer. Carla

    Coin imaging

    The first thing I recommend is reading through the guide to highlight image capture - a free download from the CHI website: http://culturalheritageimaging.org/What_We_Offer/Downloads/Capture/index.html Some of your questions are answered there. The sphere size is based on the resolution of your camera, and the field of view you have set up with the lens you are using. The recommendation (found in the guide) is to have a minimum of 200 pixels across the diameter of the sphere. The key to avoiding shadows is sphere placement. There are some good examples in the guide. The number of images we recommend is 36-48. This is not a function of the size of the subject, but about collecting a good set of data to aide the software in accurately calculating the reflectance properties and surface normals. Carla

    Cannot get HSHfitter to work

    Hmm - there should be an .lp file once you get to the execute stage. Can you check the .xml log file? It should be at the top level under the project directory. It should have the path, and also other information, and might give some clue as to the problem. You can attach it to a message here or email it to me: info at c-h-i.org (I'm trying to avoid the email address being detected by bots - but I think you can figure out what I mean. This seems to be a very unusual case. Carla

    Cannot get HSHfitter to work

    The screenshot you attached and that you linked to, both show the contents of the jpeg-exports folder. You need to look inside the assembly-files folder for a file called .lp. This is the light position file. There may be more than one of them, depending on whether you cropped your images. It doesn't matter which one you look at. Carla

    Cannot get HSHfitter to work

    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

    Trojan detected in RTIBuilder download

    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

    Cannot get HSHfitter to work

    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

    RTI for Sigillography -- DIGISIG project

    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

    Outdoor Photogrammetry: Issues and Questions

    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
  24. cdschroer

    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!
