In this tutorial, we’ll walk you through a practical use case of importing SLAM (Simultaneous localization and mapping) data into RealityScan.

Nous devons récupérer le chemin des images une par une !!!
Ce n’est pas encore au point cette nouveauté !
J’ai abandonné.
Are your images in the same folder? Typically, there is a folder for each camera. In our examples, it was necessary to link images two times for two folders.
Non mais on doit remonter les dossiers des camera_0 et camera_1 au même niveau que le fichier camera.txt. Il serait bien de l’indiquer.
perspective
|_ camera.txt
|_ camera_0
|_ camera_1
|_ points3D.txt
Maintenant me voilà bloquer avec le fichier pourtant conforme d’après votre exemple =>
It is necessary to edit the points3D.txt file to look like this:
Pourtant, j’ai bien exactement cet entête (sauf le nombre de points bien évidemment).
Merci du retour
Really exciting news!
We have tried to import data from the 3D Maker Pro Eagle Scanner, with Colmap. We get a “File not found” error when opening the “top hierarchy” cameras.txt
When using the “second level” cameras.txt the images are loaded after relinking but we get “physical end of the tape has been reached” error.
The file structure is very similar to the XGRIDS as far as i can see from images in your tutorial, but is it possible to see how the XGRIDS cameras.txt is structured?
Or can you make a tutorial for the Eagle as well? I’m sure it will be appreciated by many users.
I’ll be happy to provide you with scan data from the Eagle.
Best regards,
Carl, Swescan

Hi Carl @Swescan_AB , yes we would gladly prepare a tutorial for the Eagle as well. Please message us through the contact form, selecting ‘Technical Inquiry’. I’ll have the team forward your message to me, and I’ll set up a shared drive where you can upload the data.
Bonjour @Boilatas,
Merci d’avoir partagé votre question avec notre communauté.
Pour votre première question, normalement il devrait suffire de partager le lien du fichier, sans avoir à recréer le chemin d’accès pour chaque image. Si ce n’est pas le cas, il est possible qu’il s’agisse d’un « bug ».
Pour votre deuxième question, je ne suis pas certaine de bien comprendre la situation. Pourriez-vous, s’il vous plaît, utiliser le formulaire “Contact us” et sélectionner la catégorie “Technical” ? Il me fera plaisir de communiquer avec vous afin de mieux comprendre le problème et d’en assurer le suivi.
Merci beaucoup !

Hi, we followed the instructions as well, but we keep getting the same error message: “Track is referencing image feature which is out of bounds.”
We also checked the “points3d.txt” file, but it looks exactly as described.
We tested it with both local and georeferenced data, but it still doesn’t work.
Hi, delete all the points so that only the header remains, as shown in the screenshot. I’ll update thre tutorial to make it clear.
Any solutions with this points, i have exactly same file and it still doesn’t work?
Do you have that file with only the header as Jakub mentioned?
Yes. And it was like that initially, I didn’t edit anything.
What kind of error are you getting?
Which SLAM scanner have you used? Would it be possible to share your data with us? If so, I can send you the invitation for the data uplaod.
Lixel L2Pro, yes i can shere with you
Hello @timsa666
Thank you for your data. I’ve tested it and for me the COLMAP import worked. All I did was modifying the points3D.txt file to:
Then I’ve just opened the COLMAP file in RealityScan and I’ve used the import settings as:
After that I was asked to select the input images and the COLMAP was imported:
I’ve also tried to import the laser scan, which was aligned with the imported COLMAP.
What is the workflow you are providing?
