    Buying a Dome

    Hi Amalia, if you're still interested - we're building RTI domes with some extra UV/IR LEDs for analytical photography. Best, Tomasz https://lojewski4.wixsite.com/lojewski-agh/rti-ptm
  4. Hello Ale, just came across your question. I'm building RTI domes using this approach (addressable LEDs and Arduino controller) and it works :-) Write to me if you're still interested in this project. A video presenting the dome: https://wimic.agh.edu.pl/chmura/index.php/s/dJS5gWZjwTZb4Wf Best, Tomasz
  5. Hi all, Just wanting some opinion(s) on using the highlighting method for our project. Quick overview - We are an not for profit aeronautical society here in NZ who restores various aircraft for viewing to the public. We have a DC3 that was used by the US Navy and was flown between NZ and Antarctica (at least for part of it's life). A former US ambassador kindly donated the aircraft several years ago and it is housed in a hangar for public viewing. Unfortunately due to the age of the aircraft some of the original art work has faded. We are now attempting a project to restore the paintwork in time for the 70th anniversary of the Deep Freeze program in 2025/2026. Unfortunately any photos that exist are black and white and not of much use for some of the finer art work. We are now attempting to use RTI to extract the art work so we can recreate it on the aircraft again. My problem is the surface - A door hinge to be exact. Photo 1a below shows the area of one of the art works. Due to the door hinge I am thinking I need to break it down into three separate captures (as per the coloured outlines in the photo where we know one of the art works was). My understanding is the light source (ie flash) should be around 3 times the distance away from the area you are trying to capture. The flash should only be used between on an angle 15 to 65 degrees from the surface. My question (finally got there :)) is as follows: You can see from the second photo that the hinge extrudes out some way from the surface of the aircraft. It is unlikely I can get a capture as low as 15 degrees in the lower portion of the art work (90 degrees through 270 degrees) due to a) the hinge and b) curvature of the aircraft. Any ideas? Appreciate any help ideas Cheers Marc
  6. i need to ask you about something concerning RTI. i used it before on windows 8, but now when i downloaded the version 2.2 on windows 10, i cannot find the operation sequence Plugins in the first window in order to create a new project. do you have an idea what is happening, and why it is like this? screenshot attached... Thank you
  7. Hi All, I was wondering if it is possible from an RTI project to export the surface information (geometry, normals etc.) in any way. Thanks Andreas
  8. Hı, I want to use the RTI technique for a 22 m2 wall mural, what kind of equipment will make my job easier? What are your suggestions?
  9. I also have the same problem. I have Mac OS 11.4 and I can't open the RTIbuilder App. The error message I receive is "RTIbuilder is damaged and can't be opened. You should move it to the trash". Can anyone help me? Thank you in advance Marco
  10. 1) Pursuing on that topic, I have been trying with half of the images, no luck; another desktop, no luck. Maybe of some relevance, the W value on the HSHfitter Output Information diplay changes each time I try (I made repeated tries on a single project). I join the .xml file. Will start reducing individual image sizes, but I use a Canon EOS 5DS, size shouldn't be an issue according to other posts... so, puzzled and in need of help. 2) Kept searching since then, with image width reduced to 7500px, asking for croping gives 'Empty input file' error window (window themed 'JPEG Library Error')... gnh 3) ok, using 3 images reduced at a W of 7000px, croping works; using 3 images at the original size (W of 8688px), croping bugs => the croping step is not fit for large datasets, so a) one needs to anticipe, during data acquisition, that croping won't be possible (and, instead, hide scale, etc. and, maybe, outline the reflecting sphere, by running a preliminary image batch-processing on Photoshop) b) I'd be happy to act as tester to the RTIbuilder v3 0.xml
  11. Dear all, I am facing a similar issue with a new set of files. I am very familiar with RTIbuilder, but I just acquired a camera body delivering 50 Mpx images, and RTIbuilder seems to have trouble managing such files (set of 42 images). I had trouble getting the highlight detected, had to reinstall the builder. But now I get the 'invalid xxxx jpg library xxxx' message when I use the crop function. Instead of a W of 5895 px, the 'sample image' field displays a W of 6151224 ^^. Oddly enough, that doesn't happen when I untick the crop function. Then processing goes smooth and successful, with a displayed W of 5895 px... I'll try to reinstall the builder, but any hint would be welcome. All the best Olivier
  12. Hello All, If Anyone can share information about recent truly "3d-stereo" working lcd panels (TN, VA, IPS) it would be great. Trying to replace old 3dvision system with built-in emitter monitor and shutterglasses, but its hard to find. I know of 3dPluraview, etc, but looking for cheaper systems also for occasional stereo users. Thank You.
  13. Hi there, I'm having similar problems as others who've posted in this thread. Currently running macOS Catalina 10.15.7 and have changed security settings to allow apps from anywhere, but still receiving an error message "RTIbuilder-v2.0.2" is damaged and can't be opened. You should move it to the trash" . Strangely, the RTIViewer software opens as expected. Thanks so much for your help and any info you can provide! All the best, Aidan
  14. I too have encountered this issue. The Antivirus software on my new laptop found a Trojan Horse in the RTI Builder. What is that all about?
  15. Hello, I'm having problems to run RTI Builder V2.0.2 with macOs 11.2.3 and 11.3.1. Message is: “RTIbuilder-v2.0.2” is damneged. Someone could help me please? 🙏🏻
  16. I had this problem too. Anyone know what to do about it?
  17. 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.

    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
  20. Thanks Krl, Main thing is that you're working but it might help someone else in the future! cheers/Dave
  21. I reinstalled the software and suddenly it worked. Sorry that probably isn't very helpful. Thanks again for your advice on the setup!
  22. 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
  23. Thanks a lot. I was able to figure it out.
  24. 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
  25. 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!
  26. 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
