  2. I had this problem too. Anyone know what to do about it?
  3. Yep you are absolutely right, I was blocked by the computer Anti- virus!! I do have another Issue I'm trying to process a PTM file by the end I receive this message : un known file type .jpg I use the same files for HSH and processing RTI file no problem at all any help will be appreciated I`m working with windows 10.

    RTIBuilder

    Hi. I got new PC windows 10 and have problem to find the RTIBuilder from the download page of CHI any help would be appreciated
  6. Thanks Krl, Main thing is that you're working but it might help someone else in the future! cheers/Dave
  7. I reinstalled the software and suddenly it worked. Sorry that probably isn't very helpful. Thanks again for your advice on the setup!
  8. Thanks Krl, Especially to help anyone who might have similar problems in future, could you share what you did to make it work? cheers/Dave
  9. Thanks a lot. I was able to figure it out.
  10. Thanks Krl, I was worried when you said you were 'cropping' them - I thought you were cropping them out of the image before processing! - those boxes are just to define the search area. Secondly, just looking at your original image, I have a few observations of which only the first couple may relate to the problem you have experienced. 1. The background on which the spheres are sitting (or is behind them) looks very close in colour to the spheres, because you're using a photograph where the grey card or background is in shadow - you're not doing the circle-edge detection any favours, its trying to detect black on near-black! 2. The illumination in the shot you kindly supplied looks rather low - the recommended light positions are no lower than 15 degrees to the plane of the object, and no higher than 65 degrees to the plane of the object. 3. The highlight-detection method of RTI generation depends on accurate detection of the highlight on the sphere as each frame is processed, and using that to deduce the direction from which each frame was illuminated. The light should be reflected as a 'spot', as near to a point - but the light looks to be more like patches on your spheres? (maybe either over-illuminated or something like a flood-light used rather than as close as you can mange to a point source). 'Wide' sources won't affect the sphere detection but it will give less-distinct shadows and hence degrade the final result. 4. The whole process depends on each frame having, as close as you can, only one direction of illumination. Looking at your sample image, it looks as if the are other light sources or something out of shot that are throwing multiple direction illumination on the spheres? - that shouldn't affect the feature detection but it will degrade the final result. I'd highly recommend that you go through the RTI Capture Guide which CHI publish at http://culturalheritageimaging.org/What_We_Offer/Downloads/RTI_Hlt_Capture_Guide_v2_0.pdf - have a look at how the spheres and illumination appear in successful use. CHI also have tutorial data sets on their web site which are known to work, as well general practise they allow you to see how successful capture looks. cheers/Dave
  11. https://imgur.com/a/cYAXSdh https://imgur.com/a/ticNYo2 It looks like there's a 0.5 MB cap to these posts, but here are links to the images you requested. Thanks a lot for your help!
  12. Krl, Can you post one of your source images with the spheres, and then a screenshot of where you say you "crop out the spheres"? Dave
  13. Hello, I am relatively new to RTI, but have successfully used the software a few times. I keep getting stuck on the sphere detection step of my latest project, which is a highlight-based PTM fitter. I crop out the spheres, hit sphere detection, but once it's done the next button is still not click-able. I have deleted the project and restarted several times to no avail. I was able to make a highlight-based HSH fitter with the same piece. What am I doing wrong

    Trojan Warning

    I'm having a similar problem. Did you find any help? Thanks, Kris.
  15. Dear Mark, Thank you for well thought valuable reply, I found out you are actually the CHI’s president and co-founder, so a genuine answer indeed ! Your kind offer to discuss collaborations has been broadcast here, and we do hope that the proposal for the expanded DLN distributed enterprise features shall be funded. Thierry F.
  16. Hi there, Just wanting to find out if the issues with the latests Mac OS have been resolved? I'm still using Mojave 10.14 and I need to update so that other software works, but then my fear is that my RTI software won't. I would be updating to MacOS Big Sur Any advice very much appreciated!! Aaron.
  17. Hello, I am a newbie in this field and as a beginner I am having problem in finding interior orientation parameters of my cell phone (from which I am taking pics). Also, I am given a task to find the ground distance between two points by the formula f/H=x/X where f=focal length of phone camera H=total height x= image distance between points X= ground measurements between points The problem is that how to measure image distance. I mean if my display is small my points will show smaller difference whereas if the display is large my points will appear far. Also any app to calculate this image distance or the traditional ruler will work (accuracy issues). Attached image viewed from Cannon 60d DSLR but the image is shot from cell camera (Samsung Note 5). Thank you.

    Trojan Warning

    Hello, Every time I try to start this program, my anti-virus detects a Trojan virus and refuses to open. I am trying to learn RTI for archaeological purposes and this is the only program that I have found.
  20. Hi Thierry, Thanks for your interest in the DLN. We have made many changes to the DLN since the 2018 Beta release. Many of these changes were based on community suggestions. We are on track to release a new Beta of the expanded tool in the Spring. The full 1.0 DLN will be released by Summer this year. We would be happy to speak with you about your project ideas and send you the new Beta software when it becomes available. The current DLN release uses a standalone strategy. There are two reasons: The first is that this decision allowed us to concentrate on solving other fundamental issues; principally the solution of a broad range of technical problems and the simplification of the interface. The second reason is to encourage widespread DLN adoption by keeping the operational requirements simple, for individual scholars, small organizations, cultural communities, under-served people, and those operating in areas without robust bandwidth. CHI wants to encourage the decentralization of cultural heritage documentation. The DLN allows people all over the world to prove the quality of their documentary work (or lack thereof). This is key to the decentralization of the sources of cultural knowledge. The Postgres database allows some communication between databases on different computers using Backup/Restore functions. We understand this is awkward. The new DLN version supports XML import and export. This is convenient for exchanging database metadata. For example, if CHI joins another organization working on a project and we share equipment on a capture project, we can export our equipment kit in XML and the other organization can import it into their database for documenting the capture setups. This XML feature adds some additional ability to exchange information for small operations. There has always been an intention to produce a networked version, which is on the CHI list for future work. This “enterprise” tool would be redesigned for larger organizations with many, distributed digitization operations running at the same time. We have submitted a grant proposal to the National Endowment for the Humanities that includes planning funding for this enterprise version. The fate of the proposal will be known in August. We would like to hear ideas from larger organizations, like the Royal Library of Belgium, to make this effort responsive to the requirements of people working in our CH community. As always, we are happy to discuss collaborations. Here is a little more information about the new DLN: Among a new interface and many new features, the DLN now permits the metadata description of the processing operations applied to computational photography images that produce advanced work products, along with the description of the work products themselves. The new DLN also contains functions to automatically produce Submission Information Packets (SIPs) for archiving original images and / or work products (3D models, RTIs, Multispectral, documentary image sets, Orthomosaics…). The SIPs come in METS and Bagit wrapper formats. These formats contain manifests of the SIPs contents. The SIPs contain the archival images, work products derived from the images, the DLN metadata, relevant documents, etc. The DLN metadata comes in the form of XML and CIDOC/CRM mapped RDF. Other formats are under consideration. In addition, if all the OAIS compliant SIPs are sent to a Fedora 5 style repository, where RDF functions are available, significant self-organization of the contents will be enabled using the RDF metadata. The idea is to make the scientific imaging process as simple as possible, from the beginning all the way through the pipeline to the archival deposit. Now that this is possible, all of these functions can be adapted for a large-scale, networked organization. All that is needed are the financial resources and perhaps an expansion of our existing professional development team. But of course, this is true for all of our collective dreams for the future of cultural heritage. ––Mark

    Turning camera

    Still in the waiting of Marlin's return from holidays... I still want to know how such device can be made (or bought) for turning the camera 90° & 270° degrees. Thanks Dominique
  22. Dear Developers, The DIGIT department from the Royal Library of Belgium (www.kbr.be/en) is interested to make use in a sustainable way of the software DLN:CaptureContext v.1 Beta. Nevertheless, DIGIT dept. has two requirements for the metadata stored in the PostgreSQL DB cpt_db : • Does DLN:CC support to work with a DB cpt_db hosted on a PostgreSQL server, rather than locally ? If so, is there a way to do so (DB client / server relationship on a local network) ? • Does DLN:CC support to read & write on a common DB shared among several DLN:CC workstations (multi-clients with one shared DB hosted on a PostgreSQL server) ? Does the Cultural Heritage Imaging intend to offer those features for a forthcoming stable release ? Thanks and regards for your dedicated work, Thierry F.

  24. Hi all, Recently we have released to the public our Photogrammetry&RTI project that we have been working for over 2 years. We were inspired by some of your posts here with the dome approach and we decided that we should share with you our results. Our aim was to create a cheap, affordable photogrammetric modeling as well as RTI imaging device, that anyone can create and does not cost thousands of euros. Because of that, we needed multiple cameras, led lights and a step motor, which allowed us to rotate an object placed on the rotating table and take photos around it. As our device heart we used RaspberryPi 4 and 4 ArduCAM cameras. We were aiming at small objects, artifacts which are not bigger than 100-120mm. In the first iteration of our device we have used a small (32cm in diameter) dome (an aluminum bowl from IKEA….) with 40 led lights and 4 cameras. This version was successfully tested on Cyprus about 2 years ago where we gathered extremely valuable experience. In the second iteration we decided to leave the bowl approach and create a spider-like shape, with 10 arms for the led strips (12 leds on each) and 1 seperate arm for the cameras. It is much more mobile than the previous version as we can disassemble it and because of that it is easier to work with. Because in the first iteration we noticed that depth field was an issue, we decided to go with higher resolution cameras that have motorized focus, so we can use focus stacking method to increase our depth field. For the led strips we used flexible pcb which we connected together with FPC cables. We are controlling them through our shield that goes on the top of the raspberry pi 4. Below I am sending 2 links to my LinkedIn posts as I can not upload images here. https://www.linkedin.com/posts/marcin-k%C5%82%C4%99bowski-458bb5146_photogrammetry-rti-textured-activity-6766022368184860672-n2MF https://www.linkedin.com/posts/marcin-k%C5%82%C4%99bowski-458bb5146_photogrammetry-rti-ptm-activity-6766744323838013440-z9yn Thanks for inspiration guys and let us know what you think about our device. I am sure we will share some results as we will start testing and creating more RTI images for the objects. Marcin
  25. Hi, Yes I have had this today on my new laptop
  26. Hello, On Friday I was trying to download the Windows version of the processing software, and it triggered my pcs antivirus software claiming there was a virus threat. Has anyone else had this problem? Thanks!
