    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. 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.
  5. 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
  7. Welcome to the forum for the DLN:Inspector tool - 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 DLN:Inspector. The open source DLN:Inspector tool can be used to validate image sets created for Photogrammetry or Reflectance Transformation Imaging (RTI) You can download both the DLN tools from this page: http://culturalheritageimaging.org/What_We_Offer/Downloads/DLN/index.html There are Instructional videos describing how to work with the tools on this Vimeo channel: https://vimeo.com/channels/digitallabnotebook
  8. 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!

    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

    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
